Spectroscopy of phonon-coupled integer and fractional Chern insulators: emergence of polarons and chirality deficit of graviton mode
Min Long, Yuzhu Wang, Zi Yang Meng
Strong electron-phonon coupling can destabilize both Chern insulators (CIs) and fractional Chern insulators (FCIs) in favor of charge order, but whether the instabilities in CI and…
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…
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…
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…
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…
Optical Switching of Moiré Chern Ferromagnet
Xiangbin Cai, Haiyang Pan, Yuzhu Wang +12
Optical manipulation of quantum matter offers a non-contact, high-precision and fast control. Fractional Chern ferromagnet states in moiré superlattices are promising for topologic…
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…
Dynamics and lifetime of geometric excitations in moiré systems
Yuzhu Wang, Joe Huxford, Dung Xuan Nguyen +3
We show that spin-2 geometric excitations, known as graviton modes, generally exhibit vanishing lifetimes in lattice Chern bands, including in moiré systems. In contrast to the Lan…
Geometric Fluctuation of Conformal Hilbert Spaces and Multiple Graviton Modes in Fractional Quantum Hall Effect
Yuzhu Wang, Bo Yang
Neutral excitations in fractional quantum Hall (FQH) fluids define the incompressibility of topological phases, a species of which can show graviton-like behaviors and are thus cal…
