Irrational CFTs from coupled anyon chains with non-invertible symmetries?
António Antunes, Junchen Rong
Irrational CFTs in 1+1d with a discrete spectrum and no conserved currents other than the stress-tensor are expected to be generic, unsolvable by standard methods, and hard to cons…
Local/Short-range conformal field theories from long-range perturbation theory
Junchen Rong
We show that by imposing the conformal Wald identity, one can extract conformal data of the corresponding short-range/local CFT from the long-range perturbation theory. We first ap…
From O(3) to Cubic CFT: Conformal Perturbation and the Large Charge Sector
Junchen Rong, Ning Su
The Cubic CFT can be understood as the O(3) invariant CFT perturbed by a slightly relevant operator. In this paper, we use conformal perturbation theory together with the conformal…
Classifying irreducible fixed points of five scalar fields in perturbation theory
Junchen Rong, Slava Rychkov
Classifying perturbative fixed points near upper critical dimensions plays an important role in understanding the space of conformal field theories and critical phases of matter. I…
Quantum criticality and entanglement for two dimensional long-range Heisenberg bilayer
Menghan Song, Jiarui Zhao, Yang Qi +2
The study of quantum criticality and entanglement in systems with long-range (LR) interactions is still in its early stages, with many open questions remaining. In this work, we in…
Finite-temperature critical behaviors in 2D long-range quantum Heisenberg model
Jiarui Zhao, Menghan Song, Yang Qi +2
The Mermin-Wagner theorem states that spontaneous continuous symmetry breaking is prohibited in systems with short-range interactions at spatial dimension . For long-range…

We initiate the study of correlation functions of non-Abelian spin-1 conserved current in three dimensional conformal field theories using numerical conformal bootstrap. We discuss…

Zi Hong Liu, Weilun Jiang, Bin-Bin Chen +5
The fermion disorder operator has been shown to reveal the entanglement information in 1D Luttinger liquids and 2D free and interacting Fermi and non-Fermi liquids emerging at quan…
Fully packed quantum loop model on the square lattice: phase diagram and application for Rydberg atoms
Xiaoxue Ran, Zheng Yan, Yan-Cheng Wang +3
The quantum dimer and loop models attract great attentions, partially because the fundamental importance in the phases and phase transitions emerging in these prototypical constrai…
Spontaneous breaking of finite group symmetries at all temperatures
Pedro Liendo, Junchen Rong, Haoyu Zhang
We study conformal field theories with finite group symmetries with spontaneous symmetry breaking (SSB) phases that persist at all temperatures. We work with two theories co…

Quantum loop and dimer models are prototypical correlated systems with local constraints, which are not only intimately connected to lattice gauge theories and topological orders b…
