Dualities in one-dimensional quantum lattice models: topological sectors

L Lootens, C Delcamp, F Verstraete - PRX Quantum, 2024 - APS
It has been a long-standing open problem to construct a general framework for relating the
spectra of dual theories to each other. Here, we solve this problem for the case of one …

Gauge-invariant and anyonic-symmetric autoregressive neural network for quantum lattice models

D Luo, Z Chen, K Hu, Z Zhao, VM Hur, BK Clark - Physical Review Research, 2023 - APS
Symmetries such as gauge invariance and anyonic symmetry play a crucial role in quantum
many-body physics. We develop a general approach to constructing gauge-invariant or …

Non-abelian anyons and non-abelian vortices in topological superconductors

Y Masaki, T Mizushima, M Nitta - arXiv preprint arXiv:2301.11614, 2023 - arxiv.org
Anyons are particles obeying statistics of neither bosons nor fermions. Non-Abelian anyons,
whose exchanges are described by a non-Abelian group acting on a set of wave functions …

Ginzburg-Landau description and emergent supersymmetry of the (3, 8) minimal model

IR Klebanov, V Narovlansky, Z Sun… - Journal of High Energy …, 2023 - Springer
A bstract A pair of the 2D non-unitary minimal models M (2, 5) is known to be equivalent to a
variant of the M (3, 10) minimal model. We discuss the RG flow from this model to another …
