Quantum Simulation of Two-Dimensional Gauge Theory in Rydberg and Rydberg-Dressed Atom Arrays
Zheng Zhou, Zheng Yan, Changle Liu +2
Simulating quantum gauge theories with spatial dimension greater than one is of great physical significance yet has not been achieved experimentally. Here we propos…
Enhancing dissipative cat-state generation via nonequilibrium pump fields
Zheng-Yang Zhou, Clemens Gneiting, Wei Qin +2
Cat states, which were initially proposed to manifest macroscopic superpositions, play an outstanding role in fundamental aspects of quantum dynamics. In addition, they have potent…
Emergent Rokhsar-Kivelson point in realistic quantum Ising models
Zheng Zhou, Zheng Yan, Changle Liu +2
We show that the Rokhsar-Kivelson (RK) point in quantum dimer models (QDM) can emerge in realistic quantum Ising spin systems. Specifically, we investigate the -- tr…
Fractal Quantum Phase Transitions: Critical Phenomena Beyond Renormalization
Zheng Zhou, Xue-Feng Zhang, Frank Pollmann +1
We identify a quantum critical point with fractal symmetry whose effective theory eludes the renormalization group framework. We consider the Newman-Moore model with three-body int…
Generating and detecting entangled cat states in dissipatively coupled degenerate optical parametric oscillators
Zheng-Yang Zhou, Clemens Gneiting, J. Q. You +1
Non-Gaussian continuous variable states play a central role both in the foundations of quantum theory and for emergent quantum technologies. In particular, "cat states", i.e., two-…
Quantum dynamics of topological strings in a frustrated Ising antiferromagnet
Zheng Zhou, Chang-Le Liu, Zheng Yan +2
We investigate the quantum dynamics of the transverse field Ising model on the triangular lattice through large-scale quantum Monte Carlo simulations and stochastic analytic contin…
Stability and collisions of quantum droplets in PT -symmetric dual-core couplers
Zheng Zhou, Bo Zhu, Haibin Wang +1
We study the effect of the interplay between parity-time () symmetry and optical lattice (OL) potential on dynamics of quantum droplets (QDs) forming in a binary boso…
Floquet-surface bound states in the continuum in a resonantly driven 1D tilted defect-free lattice
Bo Zhu, Yongguan Ke, Wenjie Liu +2
We study the Floquet-surface bound states embedded in the continuum (BICs) and bound states out the continuum (BOCs)in a resonantly driven 1D tilted defect-free lattice. In contras…
Quantum tricriticality of incommensurate phase induced by quantum domain walls in frustrated Ising magnetism
Zheng Zhou, Dong-Xu Liu, Zheng Yan +2
Incommensurability plays a critical role in many strongly correlated systems. In some cases, the origin of such exotic order can be theoretically understood in the framework of 1d…
Widely existing mixed phase structure of quantum dimer model on square lattice
Zheng Yan, Zheng Zhou, Olav F. Syljuåsen +4
Since constraints hinder the application of numerical algorithms, phase diagrams of quantum dimer models are still controversial, even on the square lattice. The core controversy i…
Accessing the bath information in open quantum systems with the stochastic c-number Langevin equation method
Zheng-Yang Zhou, Yun-An Yan, Stephen Hughes +2
In traditional open quantum systems, the baths are usually traced out so that only the system information is left in the equations of motion. However, recent studies reveal that us…
Universal critical behavior in the ferromagnetic superconductor Eu(FeRu)As
Zheng Zhou, W. T. Jin, Wei Li +11
The study of universal critical behavior is a crucial issue in a continuous phase transition, which groups various critical phenomena into universality classes for revealing micros…
Protection of Logical Qubits via Optimal State Transfers
Jiang Zhang, Zheng-Yang Zhou, Lian-Ao Wu +1
Dynamical decoupling can enforce a symmetry on the dynamics of an open quantum system. Here we develop an efficient dynamical-decoupling-based strategy to create the decoherence-fr…

Zheng-yang Zhou, Mi Chen, Lian-Ao Wu +2
Dark state as a consequence of interference between different quantum states has great importance in the fields of chip-scale atomic clock and quantum information. For the -type…
Floquet control of the gain and loss in a PT-symmetric optical coupler
Yi Wu, Bo Zhu, Shufang Hu +2
Controlling the balanced gain and loss in a PT-symmetric system is a rather challenging task. Utilizing Floquet theory, we explore the constructive role of periodic modulation in c…

Zheng-Yang Zhou, Mi Chen, Ting Yu +1
One long-standing difficult problem in quantum dissipative dynamics is to solve the spin-boson model in a non-Markovian regime where a tractable systematic master equation does not…
