Digital Simulation of Non-Hermitian Knotted Bands on Quantum Hardware
Truman Yu Ng, Yuzhu Wang, Wei Jie Chan +3
Knots and links represent a fundamental motif of non-local connectivity that permeates the physical sciences from string theory to protein folds. While spectral braiding has been e…
Emergence and transition of incompressible phases in decorated Landau levels
Bo Peng, Yuzhu Wang, Bo Yang
A single Landau level (LL) dressed with periodic electrostatic potentials can realize a plethora of interacting topological phases where the Hall conductivity generally does not eq…
Microscopic geometric theory for gapped excitations in fractional topological fluids
Yuzhu Wang, Bo Yang
We propose a geometric description of all gapped excitations in fractional quantum Hall phases that reveals several fundamental understandings with experimental consequences. These…
Optical signatures of -1/3 fractional quantum anomalous Hall state in twisted MoTe2
Haiyang Pan, Shunshun Yang, Yuzhu Wang +9
The discovery of fractional charge excitations in new platforms offers crucial insights into strongly correlated quantum phases. While a range of fractional quantum anomalous Hall…
Dynamics of Anyon Clusters in Fractional Quantum Hall Fluids
Qianhui Xu, Guangyue Ji, Yuzhu Wang +2
In fractional quantum Hall fluids, the quasiparticle excitations are anyons with fractional charges and statistics. Effective interactions among the anyons can be induced by either…
Non-universal Thermal Hall Responses in Fractional Quantum Hall Droplets
Fei Tan, Yuzhu Wang, Xinghao Wang +1
We analytically compute the thermal Hall conductance (THC) of fractional quantum Hall droplets under realistic conditions that go beyond the idealized linear edge theory with confo…
