Superconductivity

[@Quantum_Tunneling]

NPTEL is one of the seriously underrated study materials - only 1 lakh views in 9 yrs........... But its content were Golden Eggs, its unfortunate that many didn't realize it. Thanks a lot, #NPTEL and Everyone involved.

[@sumeetnagpal6247]

So basically u start and comprehensive it was. Thanks Sir :)

[@prasanthsai5651]

magnetic field is allowed upto a certain value hc fot t

[@tracylove9180]

Dear Sir: The conduction of electric current through a conductor at room temperature occurs above the ground-state electron shell. If the same is true in regard to a superconductor then this draws attention to the fact that there is a difference between the environment above ground-state as compared to the environment below ground-state. I recently completed a video tutorial titled "Gravity is Electric" that I would like for you to watch and that title can be searched here on KZbin as well as Facebook. Below ground-state the temperature is Absolute Zero while above ground-state, never can that temperature be achieved.

this music in beginning,, is the best i have heard on any nptel video.

[@SunShine-rw3zs]

Yeah, at first I really didn't like it at all, but now reaching this point I find it very interesting and attractive.

[@kirannemiwal9139]

Sir your explanation is superb....I loved it

[@mahmoodasad360]

good for freshers, started from zero level upto digestive level,thanks sir..

[@bhaskarkumar1829]

best explained. thanks for your explanation

[@happybittu]

Very informative lecture Sir. Can u please explain Meissner effect, Josephson effect and SQUID in detail?

[@sabeerahmad9741]

thnku sir..May Allaha bless you.....very helpful lecture....

[@rahul_1398]

such an insightful video

[@adityabhatt0072]

Sir, after the third minute the blackboard scripts were blur. please launch in little more good video quality. I love the way you want to illustrate the lesson, but really can't understand after 3rd minute to last

[@deepakk3434]

The Boson thing went above my head !!

[@dr.pragyapalod6413]

Sir, regarding cooper pair, you explained that the electrons in a cooper pair interact via lattice vibrations, but in the superconducting state, lattice must be cool enough to vibrate. Pls explain

[@lancefarrar3442]

Dr. Prathap, When you make these "Superconductors" have you tried the EPIM [Extreme, Pressure, Ice, Molding] manufacturing process?

[@shaktipg]

31:58 you used word "type two semiconductor" or it will be superconductor..Sir clarify the same

[@kritikasharma8483]

a particle accelerator uses magnetic field for collision of atoms....they use superconductors....but superconductivity opposes magnetism as you said...so are they able to make a magnetic field while they are in their superconductivity state?????

[@muhammadkasim6783]

superconductors expell and attract an external magnetic field at the same time. it doesnts only expell

[@SalmanKhan-ut7xx]

very help full theory sir

[@aaron3g9furtado]

advertise more about this channel..because i dnt think so that many know about this channel

[@AMAL_JOY.]

Really powerful lectures Hats off 2 u sir

[@Walsh2571]

Great work.

[@kamalbelbase976]

how can i understand BCS theory

[@PinkuKumar-lx1vi]

Very good lecture . Thank sir

[@sumayyaam2685]

Thank you very much sir . It's so useful.

[@arbab64]

I find it very weird to use Ohm's law, a classical law for a quantum phenomenon, deducing that zero resistivity implies infinite electric conductivity. I think this is completely wrong conclusion. The electric conductivity should be connected by a quantum formula involving Planck's constant, mass of the electron and an electric constant like mu_0 or epsilon_0. I recommend you read my paper at Article The Fractional Hydrogen Atom: A Paradigm for Astrophysical Phenomena

[@mikefromspace]

Infinite conductivity is infact what large stars accomplish by consuming electrons to make new large particles such as Higgs Bosons. My theory online since 96 predicted the exact geometry not discovered until years later by supercomputer / see Egor Babaev's paper type 1.5 superconductivity and compare it to my models I've had here on youtube since 2008, copyrighted 2003. Specifically the 8 around 1 arrangement which is the highest possible boson format which can atomically relate to our known space and matter. I've not only proved this predictively but I've been using my knowledge of it to transmute ferrite into gold. shhh

[@dheerajreddy8345]

Why bcs theory got failed in the case of high temperature super conductors???

[@krishg2230]

sir how superconductivity depends on current density?you did not explain

[@mikefromspace]

Bosons and or whatever the largest particles currently formatting that space in balance with all other particles constitute a neutral ion charge. Out of balance means lacking mesons especially in the mix, which is the most average sized particle. In order to exclude the meson, you also make space which is formatted by large particles like bosons everywhere, to become more crystalline but also space will actually gain mass relative to other space in this fully kinetic and infinite universe as it has been discovered and now proven to great extremes, though it's hard getting through to many who have learned physics based on the photon or superstring. No physics theory ever explained superconductivity without also predicting it's exact geometry other than my own which I published on the web in 1996. So the velocity and amplitude at which magnetic current (not magnetism) kinetically interact with matter which is a 3rd pole stuck on the linear plane building block with 3 arms (fano plane is the most compressible space in the realistic kinetic model) determines the level of superconductivity because it alone, fueled by a particle exchange to and from stars which make particles and space which decays them in the passing of time (it's product), will squeeze away heat causing mid size particles like mesons in a high boson matrix which is far more inductive to electron, muon, but most especially electron neutrino passage. The electron neutrino , the smallest known particle of mass .00012x e mass, is most hydraulically superior and therefore is the source of timeflow through progressive kinetic reactions among the 3 poles, as it has now been proven in many ways.

[@venkatapavan9311]

timeline of various scientific inventions on superconductivity. Can u answer this?

[@41-siddharthabehera6]

Thank you sir 🙇

[@davidwilkie9551]

The natural coordinated state of connection of here and now, is an apparent orientation of directions of dominant probability. Although the world is not flat, we do exist in a focal plane of duality and, because the orthogonal direction of depth or distance is the sum of all points in the vanishing point of the universal singularity, we can "conduct harmonically", according to the relative states, "laws", of motion in, correspondence with the atoms of which we are constituited. Ie all distance information is harmonically linked. Superconduction is therefore inherent in space time coordinates. And the circumstances of pair bonds, latency, and the energy of state change in temperature, is orthogonal to the "bound" plane that includes magnetic effects. (It's a confusing mishmash of Orthogonality, or it would have been sorted out by Crystallography, say) That is to say, a practical researcher with extensive experience of materials would be best situated to intuit the connection process of Macro-Micro Quantum Entanglement, as it applies to the natural coordination of the universe of information (and at least prepare the ground Mathematically).

Stop criticism start learning!

[@inevitableheatdeath]

You've a good camera but you're a donkey so what use of that camera ??

[@durgaprasadsurla6239]

thank u very much sir

[@bmlavishsoni5577]

NPTEL pls clear the lens of your camera before making a video lecture😐
