Efficiency at maximum power of a quantum Carnot engine with temperature tunable baths
Junjie Liu, Chang-Yu Hsieh, Jianshu Cao
We investigate the efficiency at maximum power (EMP) of irreversible quantum Carnot engines that perform finite-time cycles between two temperature tunable baths. The temperature f…
Ultrasensitive and highly accurate long-range surface plasmon resonance biosensors based on two-dimensional transition metal dichalcogenides
Yi Xu, Chang-Yu Hsieh, Lin Wu +1
Two-dimensional transition metal dichalcogenides (TMDCs), as promising alternative plasmonics supporting materials to graphene, exhibit potential applications in sensing. Here, we…
Frequency-dependent current noise in quantum heat transfer with full counting statistics
Junjie Liu, Chang-Yu Hsieh, Jianshu Cao
To investigate frequency-dependent current noise (FDCN) in open quantum systems at steady states, we present a theory which combines Markovian quantum master equations with a finit…
Optimizing Quantum Walk Search on a Reduced Uniform Complete Multi-Partite Graph
Chen-Fu Chiang, Chang-Yu Hsieh
In a recent work by Novo et al. (Sci. Rep. 5, 13304, 2015), the invariant subspace method was applied to the study of continuous-time quantum walk (CTQW). The method helps to reduc…
A Unified Stochastic Formulation of Dissipative Quantum Dynamics. II. Beyond Linear Response of Spin Baths
Chang-Yu Hsieh, Jianshu Cao
We use the "generalized hierarchical equation of motion" proposed in Paper I to study decoherence in a system coupled to a spin bath. The present methodology allows a systematic in…
A Unified Stochastic Formulation of Dissipative Quantum Dynamics. I. Generalized Hierarchical Equations
Chang-Yu Hsieh, Jianshu Cao
We extend a standard stochastic theory to study open quantum systems coupled to generic quantum environments including the three fundamental classes of noninteracting particles: bo…
