Likelihood Is Not Authorship: Can We Reliably Measure Human Contribution in AI-Assisted Writing?
Hasan Amin, Zhuoran Lu, Ming Yin
AI-text detection generally asks whether a machine wrote a text. As AI becomes an increasingly integral and accepted part of writing, the more relevant question is no longer whethe…

Emergence of a monopole phase in the 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 Heisenberg model on the triangular lattice under an external Zeeman field 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…
