A Replica-BCS theory for dirty superconductors
Yat Fan Lau, Tai Kai Ng
In this paper, we revisit the problem of dirty superconductors using a replica-symmetric BCS (RS-BCS) theory. We apply the RS-BCS theory to dirty superconductor grains of size $L^d…
Proximity effect and Anomalous metal state in a model of mixed metal-superconductor grains
Tai Kai Ng
Motivated by the discovery of the anomalous metal state in thin film systems and suggestions that coexistence of superconducting and metallic components is crucial to the formation…
Creating Localized Majorana Zero Modes in Quantum Anomalous Hall Insulator/Superconductor Heterostructures with a Scissor
Ying-Ming Xie, Xue-Jian Gao, Tai-Kai Ng +1
In this work, we demonstrate that making a cut (a narrow vacuum regime) in the bulk of a quantum anomalous Hall insulator (QAHI) creates a topologically protected single helical ch…
Topological Superconductivity in Multifold Fermion Metals
Jason Z. S. Gao, Xue-Jian Gao, Wen-Yu He +3
Recently, multifold fermions characterized by band crossings with multifold degeneracy and Fermi surfaces with nontrivial Chern numbers have been discovered experimentally in AlPt[…
Beyond Fermi-Liquid Theory: the -Fermi liquids
Tai-Kai Ng
We study in this paper the general properties of a many body system of fermions in arbitrary dimensions assuming that the {\em momentum} of individual fermions are good quantum num…
Strongly enlarged topological regime and enhanced superconducting gap in nanowires coupled to Ising superconductors
Ying-Ming Xie, Benjamin T. Zhou, T. K. Ng +1
An external magnetic field is needed to drive a nanowire in proximity to an s-wave superconductor into a topological regime which supports Majorana end states. However, a magnetic…
