Dynamical emission of phonon pairs in optomechanical systems
Fen Zou, Jie-Qiao Liao, Yong Li
Multiphonon state plays an important role in quantum information processing and quantum metrology. Here we propose a scheme to realize dynamical emission of phonon pairs based on t…
Quantum transport in nonlinear Rudner-Levitov models
Lei Du, Jin-Hui Wu, M. Artoni +1
Quantum transport in a class of nonlinear extensions of the Rudner-Levitov model is numerically studied in this paper. We show that the quantization of the mean displacement, which…
Minimal Energy Cost to Initialize a Quantum Bit with Tolerable Error
Yu-Han Ma, Jin-Fu Chen, C. P. Sun +1
Landauer's principle imposes a fundamental limit on the energy cost to perfectly initialize a classical bit, which is only reached under the ideal operation with infinite-long time…
Optomechanical Anti-lasing with Infinite Group Delay at a Phase Singularity
Yulong Liu, Qichun Liu, Shuaipeng Wang +3
Singularities that symbolize abrupt changes and exhibit extraordinary behavior are of broad interest. We experimentally study optomechanically induced singularities in a compound s…
Criterion for a state to be distillable via stochastic incoherent operations
C. L. Liu, D. L. Zhou, C. P. Sun
Coherence distillation is a basic information-theoretic task in the resource theory of coherence. In this paper, we present the necessary and sufficient conditions under which a mi…

Georg Engelhardt, Jianshu Cao
The strong light-matter interaction in microcavities gives rise to intriguing phenomena, such as cavity-mediated transport that can potentially overcome the Anderson localization.…
Enantio-detection of cyclic three-level chiral molecules in a driven cavity
Yu-Yuan Chen, Jian-Jian Cheng, Chong Ye +1
We propose an enantio-detection method of chiral molecules in a cavity with external drive. The chiral molecules are coupled with a quantized cavity field and two classical light f…
Long-Range Non-Equilibrium Coherent Tunneling Induced by Fractional Vibronic Resonances
R. Kevin Kessing, Pei-Yun Yang, Salvatore R. Manmana +1
We study the influence of a linear energy bias on a non-equilibrium excitation on a chain of molecules coupled to local phonons (a tilted Holstein model) using both a random-walk r…
Giant Atoms in a Synthetic Frequency Dimension
Lei Du, Yan Zhang, Jin-Hui Wu +2
Giant atoms that interact with real-space waveguides at multiple spatial points have attracted extensive attention due to their unique interference effects. Here we propose a feasi…

Zheng-Yang Zhou, Ze-Liang Xiang J. Q. You, Franco Nori
Non-Hermitian systems with specific forms of Hamiltonians can exhibit novel phenomena. However, it is difficult to study their quantum thermodynamical properties. In particular, th…
Nonreciprocal frequency conversion with chiral -type atoms
