A new method for driven-dissipative problems: Keldysh-Heisenberg equations
Yuanwei Zhang, Gang Chen
Driven-dissipative systems have recently attracted great attention due to the existence of novel physical phenomena with no analog in the equilibrium case. The Keldysh path-integra…
Atomic self-organization emerging from tunable quadrature coupling
Jingtao Fan, Gang Chen, Suotang Jia
The recent experimental observation of dissipation-induced structural instability provides new opportunities for exploring the competition mechanism between stationary and nonstati…
Synthetic gauge field and chiral physics on two-leg superconducting circuits
Xin Guan, Yanlin Feng, Zheng-Yuan Xue +2
Gauge field is essential for exploring novel phenomena in modern physics. However, it has not been realized in the recent breakthrough experiment about two-leg superconducting circ…
Second-order topological insulator in a coinless discrete-time quantum walk
Ya Meng, Gang Chen, Suotang Jia
Higher-order topological insulators not only exhibit exotic bulk-boundary correspondence principle, but also have an important application in quantum computing. However, they have…
Topological quantum walks in cavity-based quantum networks
Ya Meng, Feng Mei, Gang Chen +1
We present a protocol to implement discrete-time quantum walks and simulate topological insulator phases in cavity-based quantum networks, where the single photon is the quantum wa…
Topology-dependent quantum dynamics and entanglement-dependent topological pumping in superconducting qubit chains
Feng Mei, Gang Chen, Lin Tian +2
We propose a protocol using a tunable Xmon qubit chain to construct generalized Su-Schrieffer-Heeger (SSH) models that support various topological phases. We study the time evoluti…
