Unconventional Spin Dynamics and Supersolid Excitations in the Triangular-Lattice XXZ Model
Rafael Flores-Calderón, Roderich Moessner, Frank Pollmann
Motivated by recent experiments, we investigate the spin-1/2 XXZ model on the triangular lattice with strong Ising anisotropy, combining large-scale numerical simulations and analy…
Evidence for spontaneous breaking of a continuous symmetry at a non-conformal quantum critical point in one dimension
R. Flores-Calderón, M. Zündel
In this work, we present evidence for the spontaneous breaking of a continuous symmetry in a nearest-neighbour interacting spin-1 chain tuned to a quantum critical point at b…
Higgs Phases and Boundary Criticality
Kristian Tyn Kai Chung, Rafael Flores-Calderón, Rafael C. Torres +3
Motivated by recent work connecting Higgs phases to symmetry protected topological (SPT) phases, we investigate the interplay of gauge redundancy and global symmetry in lattice gau…
Effective field theory of the quantum skyrmion Hall effect
Vinay Patil, Rafael Flores-Calderón, Ashley M. Cook
Motivated by phenomenology of myriad recently-identified topologically non-trivial phases of matter, we introduce effective field theories (EFTs) for the quantum skyrmion Hall effe…
