  2. Energy Transport in Bi-Te-Se Topological Insulators

    21 Mar 2019 | | Contributor(s):: Shouyuan Huang, Vasudevan Iyer, Xianfan Xu

    Topological insulators (TIs) are a new phase of material that allows metallic conducting electrons at its surface while the bulk is insulating. Besides, the topological surface electrons’ spin orientation is always locked perpendicular to its moving direction, called...

  6. Quantum Coherent Transport in Atoms & Electrons

    21 Jun 2017 | | Contributor(s):: Yong P. Chen

    I will discuss some recent experimental examples from my lab studying quantum coherent transport and interferometry in electrons as well as cold atoms.   For example, phase coherent electron transport and interference around a cylinder realized in a nanowire of topological insulator...

  7. Building a Topological Quantum Computer 101

    20 Jun 2017 | | Contributor(s):: Michael Freedman

    Michael Freeman shares his perspective on how we should approach building a quantum computer, starting with the mathematical roots and moving through the physics to concrete engineering and materials growth challenges on which success will hinge. He will then discuss a new, enhanced,...

  8. Topological Spintronics: from the Haldane Phase to Spin Devices

    31 Jan 2017 | | Contributor(s):: Nitin Samarth

    e provide a perspective on the recent emergence of “topological spintronics,” which relies on the existence of helical Dirac electrons in condensed matter. Spin‐ and angle‐resolved photoemission spectroscopy shows how the spin texture of these electronic states can be engineered using...

  11. 3D Topological Insulator Nanowire NEGF Simulation on GPU

    28 May 2015 | | Contributor(s):: Gaurav Gupta

    This code developed in C and CUDA simulates the carrier transport in three-dimensional (3D) topological insulator (TI) nanowire, with Bi2Se3 as exemplar material, with or without impurities, edge defects, acoustic phonons and vacancies for semi-infinite or metallic...

  13. Tutorial Introduction to Topological Insulators

    08 May 2014 | | Contributor(s):: Parijat Sengupta

    An important pursuit in semiconductor physics is to discover new materials to sustain the continuous progress and improvements in the current electronic devices.Traditionally, three material types are in use: 1) Metals 2) Semiconductors 3) Insulators. All the three material types are classified...
