Emergence of a monopole phase in the $J_{1} - J_{2}$ Heisenberg model on the triangular lattice for small magnetic fields

Sasank Budaraju, Shi Feng, Josef Willsher +3

We investigate the ground-state phase diagram of the $J_{1} - J_{2}$ Heisenberg model on the triangular lattice under an external Zeeman field $H$ by using the variational Monte Carlo…

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…
