Motional Kerr-Cat States of an Atom in an Optical Tweezer
Steven K. Pampel, Gur Lubin, Dawson P. Hewatt +6
Schrödinger cat states - quantum superpositions of classically or macroscopically distinct states - constitute a powerful resource for quantum computing, enhanced metrology, and pr…
A symmetry-protected topological optical lattice clock
Tianrui Xu, Anjun Chu, Kyungtae Kim +4
We theoretically propose a tunable implementation of symmetry-protected topological phases in a synthetic superlattice, taking advantage of the long coherence time and exquisite sp…
Does scrambling equal chaos?
Tianrui Xu, Thomas Scaffidi, Xiangyu Cao
Focusing on semiclassical systems, we show that the parametrically long exponential growth of out-of-time order correlators (OTOCs), also known as scrambling, does not necessitate…
Nonlinear optical effects in inversion-symmetry-breaking superconductors
Tianrui Xu, Takahiro Morimoto, Joel E. Moore
We study nonlinear optical responses in superconducting systems with inversion () symmetry-breaking order parameters. We first show that any superconducting system wit…
Efficient Prediction of Time- and Angle-Resolved Photoemission Spectroscopy Measurements on a Non-Equilibrium BCS Superconductor
Tianrui Xu, Takahiro Morimoto, Alessandra Lanzara +1
We study how time- and angle-resolved photoemission (tr-ARPES) reveals the dynamics of BCS-type, s-wave superconducting systems with time-varying order parameters. Approximate meth…
The effect of anisotropy of long-range hopping on localization in three-dimensional lattices
Joshua T. Cantin, Tianrui Xu, Roman V. Krems
It has become widely accepted that particles with long-range hopping do not undergo Anderson localization. However, several recent studies demonstrated localization of particles wi…
Quantum walk and Anderson localization of rotational excitations in disordered ensembles of polar molecules
Tianrui Xu, Roman V. Krems
We consider the dynamics of rotational excitations placed on a single molecule in spatially disordered 1D, 2D and 3D ensembles of ultracold molecules trapped in optical lattices. T…
