Equilibrium angular momentum and edge current in Bose-condensed cold atom systems with k-space Berry curvature
Xiao-Hui Li, Ting-Pong Choy, Tai-Kai Ng
In this paper we study the properties of cold bosons in a two-dimensional optical lattice system where Bose-condensation occurs at a momentum point k with non-zero k-space Berry cu…
Correlated spin currents generated by resonant crossed Andreev reflections in topological superconductors
James Jun He, Jiansheng Wu, Ting-Pong Choy +3
Topological superconductors, which support Majorana fermion excitations, have been the subject of intense studies due to their novel transport properties and their potential applic…
Magnetic impurities on the surface of topological superconductor
Ting-Pong Choy, K. T. Law, Tai-Kai Ng
We consider the effects of magnetic impurities on the surface of superconducting Cu doped in the odd parity pairing phase which support topologically protected Major…
Majorana fermions emerging from magnetic nanoparticles on a superconductor without spin-orbit coupling
T. -P. Choy, J. M. Edge, A. R. Akhmerov +1
There exists a variety of proposals to transform a conventional s-wave superconductor into a topological superconductor, supporting Majorana fermion mid-gap states. A necessary ing…
Interplay between Lattice Distortion and Spin-Orbit Coupling in Double Perovskites
Tyler Dodds, Ting-Pong Choy, Yong Baek Kim
We develop anisotropic pseudo-spin antiferromagnetic Heisenberg models for monoclinically distorted double perovskites. We focus on these ABB'O materials that have magnetic…
Gauge-field fluctuations in 3D topological Mott insulators
William Witczak-Krempa, Ting Pong Choy, Yong Baek Kim
We study the low-energy properties of three-dimensional (3D) topological Mott insulators which can be viewed as strong topological insulators of spinons interacting with a three-di…
