XY* transition and extraordinary boundary criticality from fractional exciton condensation in quantum Hall bilayer
XY* transitions represent one of the simplest examples of unconventional quantum criticality,
in which fractionally charged excitations condense into a superfluid and display novel …

Field-controlled multicritical behavior and emergent universality in fully frustrated quantum magnets
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 string-net models
CH Lin, FJ Burnell - Physical Review B, 2024 - APS
We study the 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 …

Machine learning the operator content of the critical self-dual Ising-Higgs lattice gauge theory
Understanding critical phenomena is of central importance to condensed-matter and high-
energy physics. Such an understanding is reflected in our ability to sort observables based …

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 …
