This lab was a great overview of the nature of quantum laboratory experiments. I learned about the different ways quantum physics is applied for entanglement, computing, and laser construction

1. The electron-electron problem 2. Mean field theory for the electron gas 3. Hartree-Fock theory 4. Screening 5. Collective excitations - plasmons 6. Integer quantum Hall effect 7. Fractional quantum Hall effect 8. Classical magnetism and the Stoner model 9. Hubbard model, antiferromagnets 10. Quantum magnetism - magnetic models, spin liquids, toric code 11. Electron-phonon interaction 12. BCS superconductivity 13. Ginzburg Landau theory of superconductors

In terms of knowledge, I have gained perspective of how to perform the entanglement experiment and demonstrate ideas in quantum mechanics using tools developed to do so. I have learnt that it is possible to violate Bell's Inequality using photons using light and that it is possible to shift the phase of the magnetic field of light. I have learnt that magnetic fields have an effect on the resistance inside a Josephson Junction when submerged in conditions enabling its superconductivity.

electron interactions, BEC, superconductivity, magnetism. (There was no time to cover quantum hall effects)

I learned superfluid. superconductor, Bose–Einstein condensate, Hartree Fork method, electron screening, Josephson junctions and spin waves in magnet.

This course is a necessary and interesting course to learn condensed matter physics.

This course will be interested to people who are new to the condensed matter physics as well as to those who are familiar with the covered topics 1 Columbia University: Arts & Sciences Fall 2022 Course: PHYSGR8083_001_2022_3-CONDENSEDMATTERPHYSICSII : PHYSGR8083_001_2022_3 - CONDENSED MATTER PHYSICS II Instructor: Abhay Narayan Pasupathy
