Description

Quantum mechanics (QM), also known as quantum physics or quantum theory, is a branch of physics providing a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. It departs from classical mechanics primarily at the atomic and subatomic scales, the so-called quantum realm. In advanced topics of QM, some of these behaviors are macroscopic and only emerge at very low or very high energies or temperatures.

  4. Computational Nanoscience, Lecture 4: Geometry Optimization and Seeing What You're Doing

    13 Feb 2008 | | Contributor(s):: Jeffrey C Grossman, Elif Ertekin

    In this lecture, we discuss various methods for finding the ground state structure of a given system by minimizing its energy. Derivative and non-derivative methods are discussed, as well as the importance of the starting guess and how to find or generate good initial structures. We also briefly...

  5. Finite Height Quantum Well: an Exercise for Band Structure

    31 Jan 2008 | | Contributor(s):: David K. Ferry

    Use the Resonant Tunneling Diodes simulation tool on nanoHUB to explore the effects of finite height quantum wells.Looking at a 2 barrier device, 300 K, no bias, other standard variables, and 3 nm thick barriers and a 7 nm quantum well, determine the energies of the two lowest quasi-bound states.

  7. Electrons in Two Dimensions: Quantum Corrals and Semiconductor Microstructures

    04 Dec 2007 | | Contributor(s):: Eric J. Heller

    The images generated by a scanning tunneling microscope are iconic. Some of the most famous are Don Eigler’s quantum corrals, which reveal not only the guest atoms on a surface but especially the interference patterns of electrons shuttling back and forth along the surface. To understand the...

  8. The basics of quantum Monte Carlo

    15 Jun 2007 | | Contributor(s):: Lucas Wagner, Jeffrey C Grossman, Jeffrey B. Neaton

    Quantum Monte Carlo is a highly accurate method to approximately solve the Schrodinger equation. I explain quantum Monte Carlo in a way that should be accessible to someone who is somewhat familiar with quantum mechanics. The discussion is mostly conceptual.Lucas Wagner is a postdoctoral...

  9. Finite Size Scaling and Quantum Criticality

    09 May 2007 | | Contributor(s):: Sabre Kais

    The study of quantum phase transitions, which are driven by quantum fluctuations as a consequence of Heisenberg's uncertainty principle, continues to be of increasing interest in the fields of condensed matter and atomic and molecular physics. In this field we have established an analogy between...
