The structure of fixed-point tensor network states characterizes patterns of long-range entanglement
Zhu-Xi Luo, Ethan Lake, Yong-Shi Wu
The algebraic structure of representation theory naturally arises from 2D fixed-point tensor network states, which conceptually formulates the pattern of long-range entanglement re…
Anomalies and symmetry fractionalization in reflection-symmetric topological order
Ethan Lake
One of the central ideas regarding anomalies in topological phases of matter is that they imply the existence of higher-dimensional physics, with an anomaly in a D-dimensional theo…
Signatures of broken parity and time-reversal symmetry in generalized string-net models
Ethan Lake, Yong-Shi Wu
We study indicators of broken time-reversal and parity symmetries in gapped topological phases of matter. We focus on phases realized by Levin-Wen string-net models, and generalize…
Rashba versus Kohn-Luttinger: Evolution of p-wave superconductivity in magnetized two-dimensional Fermi gas subject to spin-orbit interaction
Ethan Lake, Caleb Webb, D. A. Pesin +1
We study how the Rashba spin-orbit interaction influences unconventional superconductivity in a two dimensional electron gas partially spin-polarized by a magnetic field. Somewhat…
Detecting Extrasolar Asteroid Belts Through Their Microlensing Signatures
Ethan Lake, Zheng Zheng, Subo Dong
We propose that extrasolar asteroid belts can be detected through their gravitational microlensing signatures. Asteroid belt + star lens systems create so-called "pseudo-caustics",…
Gravitational Lensing by Ring-Like Structures
Ethan Lake, Zheng Zheng
We study a class of gravitational lensing systems consisting of an inclined ring/belt, with and without an added point mass at the centre. We show that a common feature of such sys…
