Many Body Localization in a Two Dimensional Itinerant SYK Model
T. Tzen Ong
We consider a two dimensional itinerant SYK model of spin-less fermions, with a linear dispersion, interacting via random long range all-to-all interactions. In the large-N limit,…
Spin Transport and Accumulation in 2D Weyl Fermion System
T. Tzen Ong, Naoto Nagaosa
In this work, we study the spin Hall effect and Rashba-Edelstein effect of a 2D Weyl fermion system in the clean limit using the Kubo formalism. Spin transport is solely due to the…
Theory of photoinduced Floquet Weyl semimetal phases
Xiao-Xiao Zhang, Tze Tzen Ong, Naoto Nagaosa
The Weyl semimetal exhibits various interesting physical phenomena because of the Weyl points, i.e., linear band-crossings. We show by Floquet theory that a linearly polarized ligh…
Entangled Orbital Triplet Pairs in Iron-Based Superconductors
T. Tzen Ong, P. Coleman, J. Schmalian
A key question in high temperature iron-based superconductivity is the mechanism by which the paired electrons minimize their strong mutual Coulomb repulsion. While electronically…
He-R: A Topological Superfluid with Triplet Pairing
T. Tzen Ong, Piers Coleman
We show that when spin and orbital angular momenta are entangled by spin-orbit coupling, this transforms a topological spin-triplet superfluid/superconductor state, such as H…
TAO pairing: a fully gapped pairing scenario for the Iron-Based Superconductors
T. Tzen Ong, Piers Coleman
Motivated by the fully gapped superconductivity in iron-based superconductors with uncompensated electron pockets, we propose a spin singlet, but orbital triplet analogue of the su…
