Logarithmic Aging Diffusion from a Multiplicative Event Clock: Rare Event Statistics, Ultraslow Transport, and Ensemble-Time Inequivalence
Chunyan Li, Zheng Li, Yueyan Li +2
Logarithmic time dependences occur in many aging materials, but neither a relaxation law nor a event rate uniquely identifies the underlying stochastic mechanism. We…
Metalization of topological insulators
Xian-Peng Zhang, Yan-Qing Feng, Ji-Feng Shao +2
In modern condensed matter theory, phases of electronic matter--such as metals and insulators-are fundamentally distinguished by the presence or absence of charge-carrying quasipar…
Magnetoresistance from decoherence
Xian-Peng Zhang, Yan-Qing Feng, Haiwen Liu +1
Microscopic theories of magnetoresistance have traditionally focused on momentum relaxation and the plasma frequency of itinerant electrons. Here, we uncover a distinct mechanism i…
Theory of quantum decoherence and its application to anomalous Hall effect
Xian-Peng Zhang, Yan-Qing Feng, Haiwen Liu +2
Coherent quantum phenomena can only emerge when decoherence is minimized, and mastery over decoherence is technologically crucial for designing and operating functional quantum dev…
Right-eigenstate-based approach to non-Hermitian superfluidity with two-body loss
Xuezhu Liu, Ming Lu, Haiwen Liu
We theoretically explore a non-Hermitian superfluid model with complex-valued interaction, inspired by two-body loss stemming from inelastic scattering observed in ultracold atomic…
First-Order PT Phase Transition in Non-Hermitian Superconductors
Xuezhu Liu, Ming Lu, Haiwen Liu +1
The interplay between superconductivity and environmental dissipation, effectively captured by non-Hermitian Hamiltonian, is a new frontier for exotic quantum phases. We explore a…
