Emergence of Competing Orders and Possible Quantum Spin Liquid in Fermions

XJ Yu, SH Shi, L Xu, ZX Li - Physical Review Letters, 2024 - APS
In the past few decades, tremendous efforts have been made toward understanding the
exotic physics emerging from competition between various ordering tendencies in strongly …

Gross-Neveu-Heisenberg criticality from expansion

K Ladovrechis, S Ray, T Meng, L Janssen - Physical Review B, 2023 - APS
The Gross-Neveu-Heisenberg universality class describes a continuous quantum phase
transition between a Dirac semimetal and an antiferromagnetic insulator. Such quantum …

Chiral bosonic quantum spin liquid in the integer-spin Heisenberg-Kitaev model

A Ralko, J Merino - Physical Review B, 2024 - APS
Motivated by the possibility of finding a bosonic quantum spin liquid in the integer spin-S
Heisenberg-Kitaev model on the honeycomb lattice, we derive a Schwinger boson mean …

Gross-Neveu-Yukawa theory of spontaneous symmetry breaking

SE Han, IF Herbut - Physical Review B, 2024 - APS
We construct and study the relativistic Gross-Neveu-Yukawa field theory for the SO (2 N) real
symmetric second-rank tensor order parameter coupled to N f flavors of 4 N-component …

Superconductivity in Luttinger semimetals near the SU (4) limit

M Kheirkhah, IF Herbut - Physical Review B, 2023 - APS
We consider the spin-3/2 Luttinger fermions with contact attraction near the SU (4)-
symmetric limit of vanishing Luttinger spin-orbit-coupling parameter responsible for band …
