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…

Terahertz range polarization rotation in the candidate time-reversal symmetry breaking superconductor BiNi
Ralph Romero, Zhenisbek Tagay, Jiahao Liang +3
Here we report the observation of time-reversal symmetry (TRS) breaking superconductivity in a BiNi bilayer using terahertz (THz) polarimetry. Leveraging a novel high-precision THz…

Observation of a dynamic magneto-chiral instability in photoexcited tellurium
Yijing Huang, Nick Abboud, Yinchuan Lv +12
In a system of charged chiral fermions driven out of equilibrium, an electric current parallel to the magnetic field can generate a dynamic instability by which electromagnetic wav…
