Quantum critical dynamics in a 5,000-qubit programmable spin glass
Experiments on disordered alloys,–suggest that spin glasses can be brought into low-
energy states faster by annealing quantum fluctuations than by conventional thermal …

Carving out OPE space and precise O (2) model critical exponents
A bstract We develop new tools for isolating CFTs using the numerical bootstrap. A “cutting
surface” algorithm for scanning OPE coefficients makes it possible to find islands in high …

Monte Carlo study of an improved clock model in three dimensions
M Hasenbusch - Physical Review B, 2019 - APS
We study a generalized clock model on the simple cubic lattice. The parameter of the model
can be tuned such that the amplitude of the leading correction to scaling vanishes. In the …

The Lorentzian inversion formula and the spectrum of the 3d O (2) CFT
A bstract We study the spectrum and OPE coefficients of the three-dimensional critical O (2)
model, using four-point functions of the leading scalars with charges 0, 1, and 2 (s, ϕ, and t) …

Pivot Hamiltonians as generators of symmetry and entanglement
It is well-known that symmetry-protected topological (SPT) phases can be obtained from the
trivial phase by an entangler, a finite-depth unitary operator $ U $. Here, we consider …

Multicritical deconfined quantum criticality and Lifshitz point of a helical valence-bond phase
The S= 1/2 square-lattice JQ model hosts a deconfined quantum phase transition between
antiferromagnetic and dimerized (valence-bond solid) ground states. We here study two …

Self-Dual Criticality in Three-Dimensional Gauge Theory with Matter
The simplest topologically ordered phase in 2+ 1 D is the deconfined phase of Z 2 gauge
theory (realized in the toric code, for example). This phase permits a duality that exchanges …

Fully packed quantum loop model on the square lattice: Phase diagram and application for Rydberg atoms
The quantum dimer and loop models attract great attention, partially because the
fundamental importance in the phases and phase transitions emerging in these prototypical …

Valence-bond solids, vestigial order, and emergent SO (5) symmetry in a two-dimensional quantum magnet
J Takahashi, AW Sandvik - Physical Review Research, 2020 - APS
We introduce a quantum spin-1/2 model with many-body correlated Heisenberg-type
interactions on the two-dimensional square lattice, designed so that the system can host a …

SO (5) multicriticality in two-dimensional quantum magnets
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 …
