M Harbola - An Introduction to Density Functional Theory

PROGRAM: STRONGLY CORRELATED SYSTEMS: FROM MODELS TO MATERIALS
DATES: Monday 06 Jan, 2014 - Friday 17 Jan, 2014
VENUE: Department of Physics, IISc Campus, Bangalore
PROGRAM LINK : www.icts.res.in/program/MTM2014
The realistic description of materials with strong electron-electron interactions is one of the challenges of modern condensed matter physics. Such a realistic description on one hand requires non-perturbative many body approaches, and on the other hand requires model Hamiltonian with material specific details offered by density functional theory (DFT). Mastering these novel techniques requires a wide background, ranging from DFT to model building and non-perturbative many body approaches such as Quantum Monte Carlo. During the last few years a major breakthrough came with the development of the DFT+Dynamical Mean Field Theory (DFT+DMFT) method. In this approach, conventional ab-initio schemes based on DFT are combined with a modern many-body approach, the dynamical mean-field theory (DMFT). In the DMFT method the full many body problem of solid state physics is mapped onto a quantum impurity model related by a self-consistency condition and the resulting impurity model is solved using non-perturbative many body techniques.
The present program has this circle of ideas as its focus. It is built around three Chandrasekhar lectures to be delivered by Prof A. Georges. In addition to these lectures there will be a school, divided into two parts, and a discussion meeting, scheduled between the two parts of the school, in which recent theoretical and experimental results on strongly correlated materials will be discussed by leading experts from India and abroad.
The school will be devoted to the following topics.
School Part I : Jan 6 -- Jan 9, 2014
a) Basic Density Functional Theory (DFT) and basis sets
b) Wannier functions
c) An introduction to many-body methods and Quantum Monte Carlo
d) Constrained LDA/RPA and Estimation of U and J
School Part II : Jan 14 -- Jan 17, 2014
a) Dynamical Mean Field Theory (DMFT)
b) Impurity Solvers
c) GW+DMFT
d) DFT+DMFT
The program is designed to educate advanced graduate students and young post-doctoral fellows in this emerging field of strongly correlated systems and to train them to carry out numerical calculations.

His doctoral students are so lucky to have such a brilliant teacher.

@@yv6358 you have no right to malign someone - neither me nor my students.

[@MrFootballAgain]

Its great that expertise of such abstract topics is at ones fingertips these days

[@69erthx1138]

He's a good teacher. He doesn't get a lot of feedback from the students. In a course of this level there should be more dialog.

Really it's great video...i m very interested to see This type video.

[@SampleroftheMultiverse]

Great video!

[@siddharthashankar6785]

Correct me if I am wrong, but at 1:02:29 when he talks about self-interaction, the last term, doesnt it look like the assumption for charge/electron not being confined to discrete points, but like a cloud, and thats how each point on the cloud experiences force from every other point in the volume.

[@rishikeshpokar6249]

Can anyone explain what he did at 52:30.

Hello sir. Generally, Slaters Determinant (the anti-symmetric wave function) is not the eigenfunction of the system. Example. Please suppose the system composed of two electrons. Electron 1 is in a hydrogen atom. Electron 2 is in a helium ion He+. rA, rB : the position of each nucleus. The two electrons are far enough. H1=(p1^2/2m)-(e^2/4πε0❘r1-rA❘), H2=(p2^2/2m)-(2e^2/4πε0❘r2-rB❘), H1φA(r1)=EAφA(r1), H2φB(r2)=EBφB(r2). Hartree productφA(r1)φB(r2) is the eigenfunction of operator H1+H2, and lead us the energy of the system EA+EB. But, another productφA(r2)φB(r1) is not the eigenfunction of operator H1+H2. (Please calculate it. It's very easy.) Therefore, the anti-symmetric wave function ψ=φA(r1)φB(r2)-φA(r2)φB(r1) is not the eigenfunction of the system.

[@P_Stark_3786]

Is doesn't lead to energy Ea + Eb. first this leads to energy Ea then Eb after that electron is fill according to pauli exclusion principles

sir i want to watch your more videos plz send me link

[@marianneketje]

I like his lecture. I initially confused him with someone with the same last name, also working in many-body physics. Is it a common name?

[@kunjalssj]

marianneketje does he happen to be in Stanford?

[@mainakghosh9466]

His name is Manoj Kumar,and title is Harbola

[@suryapravomukherjee7896]

I suppose you confused him with Dr U Harbola from IISc Bangalore

[@kunjan12345]

nice but cameraman is not good, why he is zooming this much, please show board completely

[@TheDavidlloydjones]

'Nuther wonderful video of the back of a guy's head as he writes on a blackboard, in this case a green one. The fact that it's green shows a marvellous aspect of electronic technology in education: we get to know what color the board is. Without the Internet we might never have known whether this was a black blackboard, a white whiteboard, or a green whatever. This is fantastic progress. Congratulations to the Centre for Theoretical Sciences on putting our most advanced technology to this profound use.

[@mohamedlateef5113]

good

[@emarldiv]

That chalk is satisfying

[@MoronicAcid1]

Lol LSD

[@vijayakrishna07]

Yeah. But this is more a physics thing than chemistry.

[@juandavidjaramillo9719]

Nice, but very unorganized!

[@alejandrocastellanos7139]

Juan David Jaramillo Why? If you are taking notes, you can pause if you want.

[@galvanizedcorpse]

Juan David Jaramillo I have to agree, but he's such a nice person that I can't criticize him Y no se porque mierda te escribo en yanqui si yo soy mitad Mexicano, saludos

[@galvanizedcorpse]

mi ex-novia es Sonorense... pero me mandó a la mierda :_( ... hermosas las sonorenses, vámonos a pistear carnal, y a la verga todo

I don't like any indian I knew in my life, but this professor is very cool, officially the 1st indian I like

[@sury39]

actually most of the indian professors are great teachers. try Ramamurthy Shankar, Yale university lectures on u tube;till my masters degree, in india, i had wonderful teachers; id id D.Sc in paris; but some of the lectureres were not good at all.

[@FaelCacilhas]

Besides his classes, his book on Quantum Mechanics is the best one I have ever seen!

[@PhysicsMath]

But no indian like you any way
