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…
Triangular - Heisenberg Antiferromagnet in a Magnetic Field
Thomas Bader, Shi Feng, Sasank Budaraju +3
The behavior of the paradigmatic triangular lattice Heisenberg antiferromagnet in a magnetic field remains unsettled despite decades of study. We map out the phase diagra…
Transient localization from fractionalization: vanishingly small heat conductivity in gapless quantum magnets
Shi Feng, Penghao Zhu, Johannes Knolle +1
Several candidate materials for gapless quantum spin liquids exhibit a vanishing thermal conductivity, which is at odds with theoretical predictions. Here, we show that a suppresse…
Finite Spinon Density-of-States in Triangular-Lattice Delafossite TlYbSe
Bishnu P. Belbase, Arjun Unnikrishnan, Shi Feng +3
We introduce the rare-earth delafossite compound TlYbSe -- extending the search for quantum spin liquids in frustrated triangular lattice magnets. While the DC magnetisation su…
