Van Hove Singularity-Driven Topological Magnetism in Twisted MoTe2
Heonjoon Park, Julian Stewart, Xiao-Wei Zhang +15
Van Hove singularities (vHSs) strongly amplify electron interactions and can stabilize correlated phases in topological bands. Here we report signatures of topological magnetism in…
Studying 3D O(N) Surface CFT on the Fuzzy Sphere
Jiechao Feng, Taige Wang
Boundary conformal field theory (BCFT) provides a universal framework for critical phenomena in the presence of boundaries. We determine BCFT data for the normal and ordinary bound…
Anyon molecules in fractional quantum Hall states
Taige Wang, Michael P. Zaletel
We use segment DMRG on the infinite cylinder to compute energies of charged excitations in gate-screened fractional quantum Hall states. For the Laughlin, Jain, and…
Expressibility of neural quantum states: a Walsh-complexity perspective
Taige Wang
Neural quantum states are powerful variational wavefunctions, but it remains unclear which many-body states can be represented efficiently by modern additive architectures. We intr…
Bound states of anyons: a geometric quantization approach
Qingchen Li, Pavel A. Nosov, Taige Wang +1
The question of anyon interactions and their possible binding plays a key role in the physics of fractional quantum Hall states. Here, we introduce a controlled and scalable approa…
Visualizing interaction-driven restructuring of quantum Hall edge states
Jiachen Yu, Haotan Han, Kristina G. Wolinski +10
Many topological phases host gapless boundary modes that can be dramatically modified by electronic interactions. Even for the long-studied edge modes of quantum Hall phases, formi…
