Theory of deconfined pseudocriticality

R Ma, C Wang - Physical Review B, 2020 - APS
It has been proposed that the deconfined criticality in (2+ 1) d—the quantum phase transition
between a Néel antiferromagnet and a valence-bond solid (VBS)—may actually be …

Signatures of a Deconfined Phase Transition on the Shastry-Sutherland Lattice: Applications to Quantum Critical

JY Lee, YZ You, S Sachdev, A Vishwanath - Physical Review X, 2019 - APS
We study a possible deconfined quantum phase transition in a realistic model of a two-
dimensional Shastry-Sutherland quantum magnet, using both numerical and field theoretic …

Quantum criticality and spin liquid phase in the Shastry-Sutherland model

J Yang, AW Sandvik, L Wang - Physical Review B, 2022 - APS
Using the density-matrix renormalization group method for the ground state and excitations
of the Shastry-Sutherland spin model, we demonstrate the existence of a narrow quantum …

Nematic confined phases in the U (1) quantum link model on a triangular lattice: Near-term quantum computations of string dynamics on a chip

D Banerjee, S Caspar, FJ Jiang, JH Peng… - Physical Review …, 2022 - APS
The U (1) quantum link model on the triangular lattice has two rotation-symmetry-breaking
nematic confined phases. Static external charges are connected by confining strings …

Nematic antiferromagnetism and deconfined criticality from the interplay between electron-phonon and electron-electron interactions

C Wang, Y Schattner, SA Kivelson - Physical Review B, 2021 - APS
Systems with strong electron-phonon couplings typically exhibit various forms of charge
order, while strong electron-electron interactions lead to magnetism. We use determinant …
