Simulating a Mott insulator using attractive interaction
M. Gall, C. F. Chan, N. Wurz +1
We study the particle-hole symmetry in the Hubbard model using ultracold fermionic atoms in an optical lattice. We demonstrate the mapping between charge and spin degrees of freedo…
A generic theory for Majorana zero modes in 2D superconductors
Cheung Chan, Lin Zhang, Ting Fung Jeffrey Poon +3
It is well known that non-Abelian Majorana zero modes (MZM) harbor at vortex cores in a topological superconductor, which can be realized in a 2D spin-orbit c…
Non-Abelian Majorana modes protected by an emergent second Chern number
Cheung Chan, Xiong-Jun Liu
The search for topological superconductors and non-Abelian Majorana modes ranks among the most fascinating topics in condensed matter physics. There now exist several fundamental s…
Interplay between pair density waves and random field disorders in the pseudogap regime of cuprate superconductors
Cheung Chan
To capture various experimental results in the pseudogap regime of the underdoped cuprate superconductors for temperature , we propose a four-component pair density wave (…
Dislocation Majorana zero modes in perovskite oxide 2DEG
Suk Bum Chung, Cheung Chan, Hong Yao
Much of the current experimental efforts for detecting Majorana zero modes have been centered on probing the boundary of quantum wires with strong spin-orbit coupling. The same typ…
Realizing Majorana Zero Modes by Proximity Effect between Topological Insulators and d-wave High-Temperature Superconductors
Zi-Xiang Li, Cheung Chan, Hong Yao
We theoretically study superconducting proximity effect between a topological insulator (TI) and a high-temperature d-wave superconductor (dSC). When the TI-dSC heterostructure vio…
Impurity scattering in the bulk of topological insulators
Cheung Chan, Tai-Kai Ng
We study in this paper time-reversal -impurity scattering effects in the bulk of topological insulators (TI) in two and three dimensions. Specifically we consider how impurity s…
Out of plane screening and dipolar interactions in heterostructures
Cheung Chan, T. K. Ng
Out-of-plane screening (OPS) is expected to occur generally in metal-semiconductor interfaces but this aspect has been overlooked in previous studies. In this paper we study the ef…
