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 …

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

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 …
