The Kavli ITS workshop - Majorana Modes | Masatoshi Sato

The Kavli ITS workshop on “Majorana Modes in Topological Superconductors” was held at the Kavli Institute for Theoretical Sciences (Kavli ITS) at UCAS in Beijing from January 8-11, 2019. The workshop mainly focuses on the realization and application of elusive Majorana modes in topological superconductors.

Majorana particles, which are their own antiparticles, have been of considerable interest for quantum computing in solid state systems since the zero-bias peak of the conductance was observed in the semiconductor nanowires. Now there are multiple experimental hints to support the potential existence of the Majorana states possessing zero energy. Since Majorana states can form qubits for quantum computations, once the Majorana states are able to be fully controlled and manipulated, the number of the Majorana qubits can be scalable to accelerate the speed of the quantum computation.

The scope of this workshop is to discuss the recent topics in Majorana bound states and Chiral Majorana edge modes in class D, aiming at promoting new collaborations among participants and seeking practical implementations to use Majorana modes for quantum computation. Furthermore, in the workshop, there will be a discussion session focusing on Majorana physics in the vortices of the topological superconductors.

报告摘要

Because of a unique band inversion structure, iron-based superconductors may host both topological insulating and Dirac semimetal phasesin the normal state. I will discuss resulting multiple topological superconductivity in iron-based superconductors. In particular, I will arguepossible unique superconductivity in the Dirac semimetal phase.

个人简介

My research interests have been topological excitations and other phenomena related to topology. I started my research career with study about topological solitons such as instantons or vortices, which have non-trivial topology in the configuration space. Also I developed a new method of the quantum tunneling, and studied the Seiberg-Witten theory and supersymmetry.　Recently, my research has been focused on topological phases and topological orders, which cannot be explained by the scenario of the spontaneous symmetry breaking.
