The Completely Bizarre Physics Near Absolute Zero

When we cool matter down to the coldest possible temperature, as close to absolute zero as we can, some incredibly strange quantum effects start to become apparent. Let's learn about what a superconductor, a superfluid, and a Bose-Einstein condensate is.

Crazy to think, that “hot” can reach up to trillions of degrees, yet, we comparatively live so close to absolute zero

What if there are enormous loops of complex plasma currents that could link in even more complex ways that conspire to make life forms that live in the sun. They look out and think we live so close to trillions of degrees but the universe is so bitterly cold.

I work in Superconductivity. Very interesting stuff. On accident (electrical error), one of our devices managed to cool a magnet down to 2.3K (we usually keep it around 4.2K), and that's the coldest I've ever (accidentally) made something. So I find this very interesting and fun when someone puts something like Superconductivity (electron locking) in a way that simplifies and "humanizes" the science. Thank you.

[@NorthernMike]

Im curious. How do we measure temperatures this low? How did they do it in the 1800's?

[@artemirrlazaris7406]

Measure is an imagined pattern of typically numerics, set and standard intervals, like inches. You come up with a random unit change and make it so. Each time it moves x or y in a change of temp, like mercury or eater in a glass puppet, we can start formulating things like densities and more. It all kind of happens at once. Pressure and other things involved. Typically the common human interval. Fahrenheit is 212 not hundred because Celsius was used to standing when 0 below hits things are frozen, to better communicate a relation of cold to freezing... refinement of the totality of measurement. Which means all current data is changed over... there 16 century temperature measures of areas for record keeping. As more things in reality were figured out the more most people had better lives, but specific cults hate knowledge and its join or die methodology. Envy jealous who knows... not cool. Even today science verse religion, weird nonsense, whilst your assets and means to shelter and education are attacked and all data is stolen from very cruel groups of humans.. so how it's quite simple. Make up an interval and use it as a standard.. use deduction after you calculate coefficient rates at various states and make predictions of absolute zero. Then find ways to get there and beyond. Measure is based on earth atmosphere. Eventually will have a new temperature model on a universal vacuum and a new standard thst better relates materials and function for temp. But what so I know. Barometer is also great for weather prediction, ie pressure systems. These are old, temp is in many systems.

[@olliephelan]

@@NorthernMike Lots and lots of thermometers sellotaped together to make one big quantum thermometer. In the 1800s, they just dumped convicts or free thinking women into the cryogen and record how long it took them to stop screaming. The first mental patient to die in this way was called Batholomeo O' Kelvin (hence the name , 0 Kelvin). The whole experiment was initially to treat melancholia in men and to freeze the part of a womans stomach which they believed wanted the right to vote.

[@David-ue3vf]

I work on a Heavy Ion Collider, on the cryogenic refrigerator. We keep the ring at about 4.5K all the time. We use about 3 mega watts of electricity to maintain our liquid helium system. There are some experiments that we take down to 1.9K. You can make helium liquid at 9K, but you need extremely good vacuum for that. One of the physicists that I worked with was using sound to find quenches on our beam tube. She wanted it be 1.9K. We found that the boil off is pretty noisy inside our vessel and the liquid helium transmits the sound of our compressors and vacuum systems. With isolating systems, quiet helium source, we were able to get most of the noise out and "hear" a quench. The usefulness of this is because you can recover from a quench faster as temperature doesn't transfer as well as sound in these systems. It was a fun experiment.

[@bluedotdweller]

Wow, that's really fascinating!

[@sebastianbache8862]

Too esoteric for me without some term definitions, but I can look up what a quench is, and its meaningfulness to a physcist. Has anyone ever experimented absolute zero temperatures on viruses? They are not living entities, so how do they survive in the vacumn of space? What about Tartagrades? 🩷🧡💛💚💙🩵💜❤️

[@ericchin739]

Quantum computers use magnetic fields to essentially "rotate" a qubit about an axis If you're familiar with classical computers, it's almost the same. Except, in classical computers, a bit is either on or off. A qubit can be "half on" and "half off" Or, it can be rotated about an axis to give other "values" However, those values are only used for computation. The output from a quantum computer is still the classical on/off.

[@peoplez129]

@@ericchin739 Our coding is mostly limited to 2 bits because on/off is the easiest pattern to infer data from and use electrically. There would actually be very little benefit to moving from binary. There has long since been computers that use for example 4 states instead of 2, without being quantum. But of course that also comes with overhead to convert back to binary when needed. If we could move entirely to non binary, it might be beneficial in some ways, but also a pain in others. You would still at some point have to move some aspect to binary anyways. It might make a lot of sense in the future though, when we have the ability to reliably store data in more states. When you're talking about all the data of a civilization, being able to store more of it in the same space is always good. Even then, binary could still be the primary interface, because there's not a huge reason to exclusively use anything else just yet, especially since electrically speaking, you can only really send an on/off signal. So you wouldn't just need computers capable of processing qubits, or hard drives being able to store in qubits, but you would also need a design / material scheme that can accurately transfer these bits electrically or optically. I don't know what form that would come in, either by using different types of mediums to transfer each bit (making the circuitry far more complex). It would probably only become useful when we've absolutely reached the limits of the speed of electricity itself, because at that point the only way to get any faster is to send parallel signals, just like how more pathway lanes can increase bandwidth. So it wouldn't be so much about increasing computing power overall, but more about increasing the connections of existing computing power. It may come in a simple form though, for example, we may just create a compounded circuit that is made up of several different materials that behave differently, and that acts as the physical basis for transferring qubit switches across hardware. You could potentially do the same with light waves, being not just what holds the data, but also transfers power around the circuits. Such a system would also be pretty robust, because even if some pathways are damaged, you could still build in functions that detect thing and account for it by using other qubits to fill in. And this could be how you end up with monolithic computers than can stand the test of time, look indistinguishable from a material like rock, and become almost indestructible in the sense that you could blow a chunk out of them and they'd still function.

I know a guy who's doing a doctorate at a well-known university in Cryogenic Electron Microscopy. The logic is that electron microscopes are so powerful that we can see individual molecules, maybe atoms. However, at room temperature they're buzzing around so much that you can't focus on them. But if you freeze them to near absolute zero they slow down enough to see what they're doing. Being a cynic, I wonder, if they're that cold, if they're doing anything at all.

Thank you for a beautiful presentation. Not too techy, but not boring. The superfluid having zero viscosity is mind boggling!

First time viewer. Her delivery is very engaging and clear. I do appreciate the name, a reference to Carl Sagan's Pale Blue Dot video. Excellent.

[@videoettaceo8900]

very interesting and well-presented! thank you!

The truth is, despite having access to advanced technologies and sophisticated experimental setups, researchers conducting these studies may not be any closer to reaching a definitive or factually accurate conclusion than your average quantum physics enthusiast.

between the calming music, your voice and eyes, and the hypnotic information about the universe, i fell inlove there for a minute, you took me out of this world and i loved it... thanks

You forgot this: Kamerlingh Onnes was the first to liquefy helium, in 1908, using several precooling stages and the Hampson-Linde cycle. He lowered the temperature to the boiling point of helium −269 °C (−452.20 °F; 4.15 K). By reducing the pressure of the liquid helium, he achieved an even lower temperature, near 1.5 K. These were the coldest temperatures achieved on Earth at the time and his achievement earned him the Nobel Prize in 1913.[24] Kamerlingh Onnes would continue to study the properties of materials at temperatures near absolute zero, describing superconductivity and superfluids for the first time.

Awesome video, very informative and engaging. Absolute Zero isn't really possible because other particles will still interact with it and heat it up

Physics is so much more interesting when it is explained by an intelligent and lovely woman with a great accent. Thanks for sharing Faraday's contributions- I had no idea he worked outside the field of electricity

[@alanball5750]

Fascinating stuff..The style of presentation makes you feel as if you can grasp this stuff.

[@alfredpetrossian3036]

Thank you-- Points & question: 1. MIT images of electrons at zero K is must see. 2. Harvard images of a photon slowed down at zero K - is must see. 3. The “Cold Girl?”

"If quantum physics doesn't baffle you, then you simply don't understand it". A paraphrase of Niels Bohr.

I always find it weirdly unnerving that systems can get unimaginably hot, temperatures so high that its almost meaningless to type them out, before our understanding of physics begins to break down, but the coldest temperatures where there might as well be no energy in the system at all are only a few hundred of your preferred units of temperature away

The Heisenberg uncertainty principle isn't really that unintuitive if you look at it with a macroscopic example - take a photo of a moving car. The faster your shutter speed, the more precise the position of the car is for that tiny fraction of time, but there's less information in the photo to tell you how fast it's going. Slow down the shutter speed and you get a more blurry image - the amount of this blur can tell you how fast the car is going relative to your shutter speed (ie it's energy) but it's location in the photo is smeared out so there's no precise location information, only a range of positions it held during the photo. There you go. An intuitive, macroscopic example showing how measuring both position and energy at the same time is a trade off between the accuracy of these 2 property measurements.

15:42 It probably doesn't dignify its own bit, but the reason light travels more slowly in a medium is typically less about special relativity and more about there being a delay between light being absorbed and then re-emitted by the particles in the material. You're plenty smart, that's enough info for you to see what's going on with the speed of light in a medium.

Absolute Zero times Absolute Zero = 2. Terrance Howard showed me the problem with the math.
