**Time, location:** Wednesdays, 16:15-17:45, room F3M01 (to be confirmed);

**Lecturer: ** Gergely Zaránd and András Pályi

**Language**: English

**Course Plan**:

**Principles of Random Matrix Theory**

Disordered systems and random Hamiltonians, symmetries and invariant measures, metric tensor and distances, maximum entropy principle, and joint energy distributions, GOE, GUE and GSE

**Transmission through mesoscopic conductors **

Landauer-Büttiker formula, and circular ensembles, universal conductance fluctuations;weak localization correctiondistribution of transmissions.

**Classical and quantum noise**

Classical noise, Fano factors (determination of charge); Scattering states and current operator; rigorous derivation of Landauer-Büttiker;quantum noise through a scattering region

**Coulomb blockade of grains**

Hartree terms and classical Coulomb energy; Effective Hamiltonian for grains, energy of a grain embedded into a circuit; Quantum fluctuatons and Coulomb blockade conditions; Coulomb blockade of superconducting grains (Richardson model, even-odd effect etc.)

**Transport through grains and QD's**

Anderson model and sequential tunneling through grains and/or QDs; Quantum fluctuations and Kondo effect**; **Kondo resonance, Fermi liquid theory

**Possible additional subjects:**

Dynamical Coulomb blockade and P(E) theory;

DMPK theory of a 1D conductor

Properties of Carbon nanotubes

Phase description of superconducting grains

**Requirements and grading:**

**Oral exam: **

Those, who have missed more than 2 lectures can obtain a grade by oral exam. Everyone gets two subjects on the exam.

**Problem solving:**

You can obtain a grade through problem solving in case you missed less than 3 lectures.

You will recieve 2 problem sets.

You can select problems from each set to collect 50 points at maximum (i.e. max. 100 points).

To pass (grade 2) you need to reach 50%, for grade 3 you need 60%, for grade 4 you need to reach 70%, and for grade 5, you must score above 80%.

You may discuss with the others (or with us), give hints to each-other, but we request independent work: you may help each-other but you are not allowed to copy

Deadlines will be specified in the problem sets.

**Term paper: **

Instead of problem solving, you can pass by handing in a 15 page long term paper, too, in case you missed less than 2 lectures. The term paper is supposed to start with a 8-10 pages introduction, putting your subject into context and revising the relevant material of the course, and the last 8-10 pages are supposed to discuss a hand-out (publication or book chapter). You do not need to understand all details of the handout, but the text must be clear and logical, reflecting your clear understanding.
