...agree When a lecturer fluently flows through a complex subject such as this without referring to written notes he/she is not only an expert in the area, but also a great communicator and teacher I wish all of my teachers were like Prof Balakrishnan. He has a calming sort of voice and peaceful body language. Like a Quantum Buddha

Topics covered: 1. A quick summary of Hermite polynomials - Rodrigues Formula, Generating function. 2. Invariance under Fourier transform between the position and momentum eigenbasis. 3. The Heisenberg uncertainty relation for various energy eigenstates, particularly ground state being a minimum uncertainty state. 4. Eigenvalues problems of the creation and annihilation operators: creation operators have non-normalizable eigenfunctions, which have no expansions in the Fock-state basis, annihilation operators: coherent states. 5. Properties of Coherent state: cardinality of coherent states, orthogonality of coherent states, over-completeness of coherent states, position eigenbasis form of coherent states.

This series of lectures on quantum physics, with graphic explanations are better than any I know. Prof. Balakrishnan is the best.

7:36 onwards (mom space wave function) what a beauty 😍

[@nonporous]

Incredible! I wish I knew more about the theory of lie algebras and lie groups.

Amazing lecture

[@PrashVerse]

Lecture flowing like quantum energy.....

[@goutamrajkumar14]

excellent lecture for I I T and Engineering students

[@X3QT0R]

This is an undergrad course in some colleges ( especially IIT) and MSc(Masters) level in many universities. (even in some IIT)

[@DaveJohnsonsuvam]

dude its not memory . he has SOLID concepts and indepth understanding of qm and also lots of experience

[@vijayyadav-ki4lm]

its nice

[@RandomIndian001]

@lomje70 This is an QM course of MSc LEVEL in INDIA

[@ayeshakawakil845]

Ya, I am engineer and referring to it

[@AshishUniyal1]

54:22, Hahaha unexpected XD

[@maujo2009]

And I thought I knew QM! AWESOME!

[@zainshah6689]

Hi sir can u send me notes of your lecturers

[@GuillermoValleCosmos]

How does he get the reduction of the operator for the coherent states?? I tried and didn't get what he got!

[@Darthlnvader]

uh huh but do you sell cigarettes in your corner dairy shop?
