DOI: 10.1007/s11071-020-06091-7
Abstract: The phase reduction approach has manifested its power in analyzing the rhythmic behaviors for limit cycle oscillators. For coherent oscillation purely induced by noise, e.g., the coherence resonance oscillator, the stochastic dynamics exhibit almost deterministic… read more here.

Abstract: Abstract In this paper, we investigate the quantum interference of output port by considering any photon-number state and photon-added coherent states (PSCS) as inputs of Mach-Zehnder interferometer. We re-present the relationship between input and output… read more here.

DOI: 10.1364/oe.476822
Abstract: We propose an alternative scheme for phase estimation in a Mach-Zehnder interferometer (MZI) with photon recycling. It is demonstrated that with the same coherent-state input and homodyne detection, our proposal possesses a phase sensitivity beyond… read more here.
