New developments in the numerical conformal bootstrap

S Rychkov, N Su - Reviews of Modern Physics, 2024 - APS
Over the past 15 years, the numerical conformal bootstrap has become an indispensable
tool for studying strongly coupled conformal field theories in various dimensions. Reviewed …

Bootstrapping deconfined quantum tricriticality

SM Chester, N Su - Physical Review Letters, 2024 - APS
The paradigmatic example of deconfined quantum criticality is the Neel to valence bond
solid phase transition. The continuum description of this transition is the N= 2 case of the …

Extracting subleading corrections in entanglement entropy at quantum phase transitions

M Song, J Zhao, ZY Meng, C Xu, M Cheng - SciPost Physics, 2024 - scipost.org
We systematically investigate the finite size scaling behavior of the Rényi entanglement
entropy (EE) of several representative 2d quantum many-body systems between a …

Quantum oscillations in the hole-doped cuprates and the confinement of spinons

PM Bonetti, M Christos, S Sachdev - … of the National Academy of Sciences, 2024 - pnas.org
A long-standing problem in the study of the under-hole-doped cuprates has been the
description of the Fermi surfaces underlying the high magnetic field quantum oscillations …

Emergent self-duality in a long-range critical spin chain: From deconfined criticality to first-order transition

S Yang, Z Pan, DC Lu, XJ Yu - Physical Review B, 2023 - APS
Over the past few decades, tremendous efforts have been devoted to understanding self-
duality at the quantum critical point, which enlarges the global symmetry and constrains the …

Deconfined quantum criticality of nodal -wave superconductivity, Néel order, and charge order on the square lattice at half-filling

M Christos, H Shackleton, S Sachdev, ZX Luo - Physical Review Research, 2024 - APS
We consider a SU (2) lattice gauge theory on the square lattice, with a single fundamental
complex fermion and a single fundamental complex boson on each lattice site. Projective …

Emergent conformal symmetry at the multicritical point of SO(5) model with Wess-Zumino-Witten term on a sphere

BB Chen, X Zhang, ZY Meng - Physical Review B, 2024 - APS
Critical phenomena beyond the Landau-Ginzburg-Wilson paradigm have been long sought
after. Among many candidate scenarios, the deconfined quantum critical point (DQCP) …

Phases and exotic phase transitions of a two-dimensional Su-Schrieffer-Heeger model

A Götz, M Hohenadler, FF Assaad - Physical Review B, 2024 - APS
We study a Su-Schrieffer-Heeger electron-phonon model on a square lattice by means of
auxiliary-field quantum Monte Carlo simulations. The addition of a symmetry-allowed …

Spin-Peierls instability of deconfined quantum critical points

D Hofmeier, J Willsher, UFP Seifert, J Knolle - Physical Review B, 2024 - APS
Deconfined quantum critical points (DQCPs) are putative phase transitions beyond the
Landau paradigm with emergent fractionalized degrees of freedom. The original example of …

SO (5) multicriticality in two-dimensional quantum magnets

J Takahashi, H Shao, B Zhao, W Guo… - arXiv preprint arXiv …, 2024 - arxiv.org
We resolve the nature of the quantum phase transition between a N\'eel antiferromagnet and
a valence-bond solid in two-dimensional spin-1/2 magnets. We study a class of $ J $-$ Q …
