XY* transition and extraordinary boundary criticality from fractional exciton condensation in quantum Hall bilayer

YH Zhang, Z Zhu, A Vishwanath - Physical Review X, 2023 - APS
XY* transitions represent one of the simplest examples of unconventional quantum criticality,
in which fractionally charged excitations condense into a superfluid and display novel …

[HTML][HTML] Field-controlled multicritical behavior and emergent universality in fully frustrated quantum magnets

Y Fan, N Xi, C Liu, B Normand, R Yu - npj Quantum Materials, 2024 - nature.com
Phase transitions in condensed matter are a source of exotic emergent properties. We study
the fully frustrated bilayer Heisenberg antiferromagnet to demonstrate that an applied …

Anyon condensation in the string-net models

CH Lin, FJ Burnell - arXiv preprint arXiv:2303.07291, 2023 - arxiv.org
We study condensation of abelian bosons in string-net models, by constructing a family of
Hamiltonians that can be tuned through any such transition. We show that these …

Quantum robustness of the toric code in a parallel field on the honeycomb and triangular lattice

V Kott, M Mühlhauser, JA Koziol, KP Schmidt - arXiv preprint arXiv …, 2024 - arxiv.org
We investigate the quantum robustness of the topological order in the toric code on the
honeycomb lattice in the presence of a uniform parallel field. For a field in $ z $-direction, the …

Emergent criticality in fully frustrated quantum magnets

Y Fan, N Xi, C Liu, B Normand, R Yu - arXiv preprint arXiv:2306.16288, 2023 - arxiv.org
Phase transitions in condensed matter are often linked to exotic emergent properties. We
study the fully frustrated bilayer Heisenberg antiferromagnet to demonstrate that an applied …

L Oppenheim, M Koch-Janusz, S Gazit, Z Ringel - ml4physicalsciences.github.io
Extracting the operator spectrum (conformal towers) of critical models with spacetime
dimensionality larger than 2 is a formidable numerical task, closely related to diagonalizing …
