Emergence of a monopole phase in the Heisenberg model on the triangular lattice for small magnetic fields
Sasank Budaraju, Shi Feng, Josef Willsher +3
The authors use variational Monte Carlo to map the ground‑state phase diagram of the J1‑J2 Heisenberg model on a triangular lattice under small Zeeman fields, revealing a monopole‑…

Tensor network study of deconfined quantum criticality in a one-dimensional spin-phonon model
Anton Romen, Josef Willsher, David Hofmeier +2
Deconfined quantum critical points (DQCPs) describe continuous transitions between ordered phases beyond the Landau paradigm. A simple example is the Néel antiferromagnet (AFM) to…

Electrical observation via spin Seebeck effect of fractionalized excitations in a magnetic insulator
Nan Tang, Josef Willsher, Stephan Glamsch +9
Fractionalized excitations are among the most striking signatures of emergence in quantum matter. While widely sought in frustrated magnets, their detection and characterization re…
