Nonperturbative Nonlinear Hall Effect in Nonequilibrium Steady States
Lei Geng, Martin Eckstein, Lei Chen +4
The nonlinear Hall effect in quantum materials has attracted broad interest, yet most existing studies focus on the weak-field, perturbative regime. Here we develop a nonperturbati…
Amplified response of cavity-coupled quantum-critical systems
Shouvik Sur, Yiming Wang, Mounica Mahankali +2
A quantum critical point develops when matter undergoes a continuous transformation between distinct ground states at absolute zero. It hosts pronounced quantum fluctuations, which…
Chiral Weyl-Kondo semimetals and hexagonal heavy fermion systems
Kuan-Sen Lin, Yuan Fang, Henrique Fabrelli +7
Strong correlation, in concert with symmetry and topology, engenders novel gapless phases of matter, though only a tip of the iceberg has been seen. An exemplary framework is provi…
Perturbative Kondo destruction and global phase diagram of heavy fermion metals
Yiming Wang, Shouvik Sur, Chia-Chuan Liu +1
Strange metals represent a foundational problem in quantum condensed matter physics, and heavy fermion systems provide a canonical setting to advance a general understanding. The c…
Suppression of shot noise at a Kondo destruction quantum critical point
Yiming Wang, Shouvik Sur, Fang Xie +4
Strange metal behavior has been observed in an expanding list of quantum materials, with heavy fermion metals serving as a prototype setting. Among the intriguing questions is the…
Amplified multipartite entanglement witnessed in a quantum critical metal
Yuan Fang, Mounica Mahankali, Yiming Wang +4
Strong correlations in matter promote a landscape of quantum phases and associated quantum critical points. For metallic systems, there is increasing recognition that the quantum c…
