Quantum Fisher information of magnetic quantum phase transition on Kondo lattice
Yuan Fang, Lei Chen, Mounica Mahankali +4
Strange metals exemplify highly collective quantum many-body systems that call for new means of characterization, and there is considerable potential for quantum information approa…
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…
Dual-use quantum hardware for quantum resource generation and energy storage
Vaibhav Sharma, Yiming Wang, Shouvik Sur
Efficient generation of quantum resources is a central objective of modern quantum technological platforms. Independently, quantum batteries have emerged as nanoscale devices that…
Nonlinear thermal and thermoelectric transport from quantum geometry
Yuan Fang, Shouvik Sur, Yonglong Xie +1
Quantum geometry may enable the development of quantum phases ranging from superconductivity to correlated topological states. One powerful probe of quantum geometry is the nonline…
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…
