Scalable Fermionic Error Correction in Majorana Surface Codes
Oscar Viyuela, Sagar Vijay, Liang Fu
We study the error correcting properties of Majorana Surface Codes (MSC), topological quantum codes constructed out of interacting Majorana fermions, which can be used to store qua…
High-frequency rectification via chiral Bloch electrons
Hiroki Isobe, Su-Yang Xu, Liang Fu
Rectification is a process that converts electromagnetic fields into a direct current. Such a process underlies a wide range of technologies such as wireless communication, wireles…
Spin-Orbital Density Wave and a Mott Insulator in a Two-Orbital Hubbard Model on a Honeycomb Lattice
Zheng Zhu, D. N. Sheng, Liang Fu
Inspired by recent discovery of correlated insulating states in twisted bilayer graphene (TBG), we study a two-orbital Hubbard model on the honeycomb lattice with two electrons per…
de Haas-van Alphen effect of correlated Dirac states in kagome metal Fe3Sn2
Linda Ye, Mun K. Chan, Ross D. McDonald +7
The field of topological electronic materials has seen rapid growth in recent years, in particular with the increasing number of weakly interacting systems predicted and observed t…
Nematic superconductivity stabilized by density wave fluctuations: Possible application to twisted bilayer graphene
Vladyslav Kozii, Hiroki Isobe, Jörn W. F. Venderbos +1
Nematic superconductors possess unconventional superconducting order parameters that spontaneously break rotational symmetry of the underlying crystal. In this work we propose a me…
Observation of the nonlinear Hall effect under time reversal symmetric conditions
Qiong Ma, Su-Yang Xu, Huitao Shen +18
The electrical Hall effect is the production of a transverse voltage under an out-of-plane magnetic field. Historically, studies of the Hall effect have led to major breakthroughs…
