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…
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…
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.…
