Hysteresis without coexistence: disorder-rounded first-order transitions in a van der Waals magnet
Xiaoyu Guo, Abby N. Neill, Christopher M. Pasco +2
Quenched disorder can profoundly modify phase transitions. In low-dimensional systems, theory predicts that even weak quenched disorder can round the thermodynamic discontinuities…

Many-body quantum geometric effects and entanglement at the 3D metal-insulator quantum phase transition
Jason Y. Yan, Xiaoyu Guo, R. Bhandia +3
Quantum geometry has emerged as a unifying concept across condensed matter physics, underlying phenomena from nonlinear topological response to flat-band superconductivity. While u…
