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…
Classical fully-packed loop model with attractive interactions on the square lattice
Bhupen Dabholkar, Xiaoxue Ran, Junchen Rong +4
We study a classical model of fully-packed loops on the square lattice, which interact through attractive loop segment interactions between opposite sides of plaquettes. This study…
Scalar Conformal Field Theories from Lattice Systems
Junchen Rong
We discuss scalar conformal field theories (CFTs) that can be realized in structural phase transitions. The Landau condition and Lifshitz condition are reviewed, which are necessar…
Non-Abelian currents bootstrap
Yin-Chen He, Junchen Rong, Ning Su +1
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…
