U r lifesaver sir.. whenever a doubt comes..u r there with a new video. Great efforts of urs. 👏

[@shikhaa0981]

Thanku so much for this beautiful explaination don't get bothered about the time. Its really a grt explaination. Can u plzzz explain the perturbation theory and creation and anhilation operators plzzzz

[@aratimaurya7825]

Thank you sir nice explanation.....sir plz make videos on wav function

[@ahmedsalafap5898]

Thak you. Its really informative

[@sobiakhan709]

Very much useful thanks a lot sir

[@dikitalukdar7288]

Thank you sir, please make videos on remaining topics of quantum also......

[@santoshbhattarai5817]

That's great sir

[@muthiahpillaipalanichamy3939]

Awesome young boy. Keep going

[@nishantbiswakarma61]

Sir, can you solve some questions from variational method and perturbation theory?? It would be really helpful.

[@powerfulfocus123]

Thanks sir for this video

[@sudheer2643]

Thanks a lot sir

[@khushikhushi9969]

Tqqq... it is very helpful to me

[@kanchansingh1011]

Bhut achha pdaya aapne sir.... I hv a problem....if all physically observable operators like position and momentum are hermition operator..then why they are not commute with each other... Pls sir..clear my doubt..

[@jyotibhatt8117]

Thank you sir.

[@bhavanarajasekhar5886]

Thanku so much sir

[@kanchantomar8833]

Sir u r great teacher☺thanku sir

[@neerajtyagi7178]

Sir, if we put g=f then it will give expectation value?

[@kiran....5280]

Sir please make video on hydrogen atom...

[@dikshaaggarwal2909]

sir please tell the answer of the question asked by you in the end of the video....

[@gopalkrishnaniyogi5941]

Sir plz make a videos on reductive elimination reaction sir in english voice.

[@tuhinpatra697]

when will csir net December 2017 result be published?plz reply

[@remyavasudevan9302]

Pls give the link to download MC qurrie Quantum chemistry

[@vireshpomajichemproblems8508]

Last problem answer is hermition this is write or wrong sir ans me

[@sudipnale7664]

How to prove whether L square is hermitian ?

[@mrinmoymandal2695]

I have a question sir---If two Hermitian oparetors A &B commutes.. Then can I say that every eigen vector of A is necessary to be the eigen vectors of B??

[@afiyashaikh1434]

MRINMOY MANDAL When two operators commutes let say momentum operator and KE operator then they have different eigen values. Momentum operator gives momentum whilst KE operator gives KE and commutes means whether they can be calculated with certainity or not as per heisenberg uncertainty principle. It has nothing to do with eigen values. Correct me if I am wrong.

[@dhruvikhanna4914]

Sir is this 7th lecture of quantum mechanics?

[@afiyashaikh1434]

Sir, I have a doubt may be it sound illogical. We talk operators as real or imaginary and in mathematics every imaginary is term is associated with i and in hamiltonian operator we have i, how I should take that I.

[@mrinmoymandal2695]

afiya shaikh see,if u r interested about an oparetor (with imaginary term) opareting on wave fun(psi)..then u have no need to worry about that imaginary term bcz a wave fun always consist of an imaginary term also..for calculation if p-si is not given just do proper integration to check,, I think I cleared your doubts.. Thank you

[@afiyashaikh1434]

MRINMOY MANDAL So, that imaginary term is due to wavefunction and not have any other physical significance?

[@darshnadevi2857]

Why benzoyl group prefer hydrogenolysis?????? Plzzz plzzz tell anybody /sir???

[@darshnadevi2857]

Gate chemistry sir????

[@buddhadebmondal5531]

I didn't understand your qstn?

[@HarpreetSingh-cd2ng]

Not hermitian If A= -d/dx+x then Product of (A and A adjoint ) will come out to be hermitian..

[@vijayprabhakaran8380]

Do video on heterocyclic sir.

[@mrinmoymandal2695]

One more question plzz eigen values of a non-hermitian oparetors are always imaginary??

[@tarunyadav5938]

Non hermitial oporetor may have no eigan value ...eigan value is a value its not be imaginary any way

[@mrinmoymandal2695]

When any oparetor oparates on a eigen fun then it gives a certain eigen value yes it may be 0 value....bcz we can rewrite every quantum oparetor in Matrix formation...then without making any sorts of calculation u can't say where it's limits....as an example e^(i d/DX)

[@tarunyadav5938]

If d/DX oporate in a oporator like x or x square then not get the eigen function back like A¥=a¥ so no eigen function no eigen value

[@pragatiswain6914]

No.. not at all. Here we talk only about Quantum mechanical operators which involve mind boggling functions of sin cos or exponential. Thats why chances of imaginary values or functions come. But for simple mathematical operations We regularly use operators of Multiplication × Division ÷ Addition + Substraction - And these operators when operated on real functions give real values And When operated on imaginary functions give imaginary values. Example If A^ = + F(x)= 4, G(x)=5 F(x) A^ G(x) = 4+5=9 (real) But if F(x) is 4i then, F(x) A^ G(x) = 4i+5 (imaginary) Am I right!

[@tarunyadav5938]

pragati swain actually the question is about imaginary eigen value not about imaginary value

[@vipinsingh2589]

Eigen value can be zero?

[@buddhadebmondal5531]

No

[@priyaranjansahoo8024]

Sir this is hermitian

[@successfull_introvert]

Is Coaching mandatory to crack CSIR NET???

[@seemaneyaz6297]

Neither hermitian nor anti hermitian

[@shivaswamychannegowda9519]

Hi ,d/dx is an hermitian operator na.

[@shivaswamychannegowda9519]

Sorry it is d/d(theta).can u also tell about sin theta

[@pragatiswain6914]

If I denote dagger(+) as (") (-d/dx+x)" = (-d/dx)" + x" = d/dx + x If (A-B)" = A+B Then (A-B) is neither Hermitian nor Anti-hermitian.

[@shikhalalwani7240]

Can u plz elaborate over this?

[@electrotech9444]

hermitian

[@sobiakhan709]

Hermitian

[@dikshaaggarwal2909]

please if u could tell me how is it hermitian?
