Arbitrary Control of Non-Hermitian Skin Modes via Disorder and An Electric Field
Zhao-Fan Cai, Yang Li, Yu-Ran Zhang +4
The non-Hermitian skin effect (NHSE), characterized by the accumulation of a macroscopic number of bulk states at system boundaries, is a hallmark of non-Hermitian physics. However…
Scattering States in One-Dimensional Non-Hermitian Baths
Jimin Li, Yuwen E. Zhang, Franco Nori +1
A single quantum emitter coupled to a structured non-Hermitian environment shows anomalous bound states and real-time dynamics without Hermitian counterparts, as shown in [Gong et…
Characterizing Many-body Dynamics with Projected Ensembles on a Superconducting Quantum Processor
Zhiguang Yan, Zi-Yong Ge, Rui Li +3
Quantum simulators offer a new opportunity for the experimental exploration of non-equilibrium quantum many-body dynamics, which have traditionally been characterized through expec…
Versatile Control of Nonlinear Topological States in Non-Hermitian Systems
Zhao-Fan Cai, Yu-Chun Wang, Yu-Ran Zhang +2
The non-Hermitian skin effect (NHSE) and nonlinearity can both delocalize topological modes (TMs) from the interface. However, the NHSE requires precise parameter tuning, while non…
Microwave interference from a spin ensemble and its mirror image in waveguide magnonics
B. -Y. Wu, Y. -T. Cheng, K. -T. Lin +10
We investigate microwave interference from a spin ensemble and its mirror image in a one-dimensional waveguide. Away from the mirror, the resonance frequencies of the Kittel mode (…
Dissipation and Interaction-Controlled Non-Hermitian Skin Effects
Yang Li, Zhao-Fan Cai, Tao Liu +1
Non-Hermitian skin effects (NHSEs) have recently been extensively studied at the single-particle level. When many-body interactions become dominant, novel non-Hermitian phenomena c…
Identifying Entanglement Phases with Bipartite Projected Ensembles
Zi-Yong Ge, Franco Nori
We introduce bipartite projected ensembles (BPEs) for quantum many-body wave functions, which consist of pure states supported on two local subsystems, with each state associated w…
Chiral-Extended Photon-Emitter Dressed States in Non-Hermitian Topological Baths
Zhao-Fan Cai, Xin Wang, Zi-Xuan Liang +2
The interplay of quantum emitters and non-Hermitian structured baths has received increasing attention in recent years. Here, we predict unconventional quantum optical behaviors of…
Nonlinear cascaded quantum network with giant emitters
Xin Wang, Jia-Qi Li, Zhihai Wang +4
Chiral quantum optics is central to developing scalable quantum networks, yet existing approaches rely predominantly on linear single-photon regimes. It remains unclear how to gene…
Interplay between disorder and topology in Thouless pumping on a superconducting quantum processor
Yu Liu, Yu-Ran Zhang, Yun-Hao Shi +24
Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontriv…
Anderson Delocalization in Strongly Coupled Disordered Non-Hermitian Chains
Wei-Wu Jin, Jin Liu, Xin Wang +7
Disorder and non-Hermitian effects together can upend how waves localize. In a 1D disordered chain, the non-Hermitian skin effect (NHSE) can induce Anderson delocalization, defying…
Effective Field Theories and Finite-temperature Properties of Zero-dimensional Superradiant Quantum Phase Transitions
Zi-Yong Ge, Heng Fan, Franco Nori
The existence of zero-dimensional superradiant quantum phase transitions seems inconsistent with conventional statistical physics. This work clarifies this apparent inconsistency.…
