  3. CQT Introduction

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    A short overview of this series of four lectures is given.

  4. CQT Lecture 1: Nanodevices and Maxwell's Demon

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective: To illustrate the subtle interplay of dynamics and thermodynamicsthat distinguishes transport physics.

  5. CQT Lecture 2: Electrical Resistance - A Simple Model

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective:To introduce a simple quantitative model for describing current flow in nanoscalestructures and relate it to well-known large scale properties like Ohm’s Law.

  6. CQT Lecture 3: Probabilities, Wavefunctions and Green Functions

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective: To extend the simple model from Lecture 2 into the full-blown model combines the NEGF (Non-Equilibrium Green Function) method with the Landauer approach.

  7. CQT Lecture 4: Coulomb blockade and Fock space

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective: To illustrate the limitations of the model described in Lectures 2, 3 and introduce a completely different approach based on the concept of Fock space. I believe this will be a key concept in the next stage of development of transport physics.
