Investigation of Emerging Quantum Materials and Topological Order
Abstract
Title: Investigation of Emerging Quantum Materials and Topological OrderObjective: This proposal aims to experimentally investigate two major areas in the forefronts of condensed matter physics ~ topological insulators (TI) and Majorana fermions (MF) having built up sound foundation in these areas in the last three years under a previous ONR grant. Approach: PI will use MBE techniques under UHV condition to grow high quality thin films and their heterostructures. PI will further characterize the samples and carry out transport measurements, to study the novel physical effects and phenomena and assess their significance for future low power electronic device/circuits. SOW: Specific Research Tasks are:Task 1. Study coherent quantum transport in magnetic topological insulators (MTI).1.1. Experiments to measure and characterize quantum anomalous Hall (QAH) state in topological insulators (TI). 1.2. Detect spin polarized chiral edge mode in QAH state 1.3. Achieve high-temperature MTI phase by proximity coupling1.4. Study coexistence of TI with ferromagnetism/superconductivity.Task 2. Search for Majoranas ~ detection and braiding. Aim is to create Majorana Bound States (MBS) and search for Majoranas in superconducting p-wave surface states in Au, Merits and Relevance: The research tasks outlined in this proposal is highly synergistic with an on-going ONR Basic Research Challenge (BRC) program, where Majorana phenomena are being probed in 1D nanowire geometry. Majorana bound states (MBS) are fascinating new physical phenomena that could potentially enable the ultimate fault-tolerant quantum information technology.
