Eigenstates Transition without Undergoing an Adiabatic Process [PDF]
Physical Review Letters, 2019 We introduce a class of non-Hermitian Hamiltonians that offers a dynamical approach to short-cut to adiabaticity (DASA). In particular, in our proposed 2 * 2 Hamiltonians, one eigenvalue is absolutely real and the other one is complex. This specific form of the eigenvalues helps us to exponentially decay the population in an undesired eigenfunction or ...

Adiabatic Processes in Quantum Optics [PDF]
Acta Physica Polonica A, 2002 This paper reviews the use of adiabatic approximations in quantum optics.The general principle is explained in terms of the Landau-Zener model and the recently developed stimulated Raman adiabatic passage scheme. The features characteristic of adiabatic evolution are extracted from these examples.

Accelerating an adiabatic process by nonlinear sweeping [PDF]
Chinese Physics B, 2013 We investigate the acceleration of an adiabatic process with the same survival probability of the ground state by sweeping a parameter nonlinearly, fast in the wide gap region and slow in the narrow gap region, as contrast to the usual linear sweeping.

Non-Hermitian heat engine with all-quantum-adiabatic-process cycle [PDF]
, 2016 As a quantum device, a quantum heat engine (QHE) is described by a Hermitian Hamiltonian. However, since it is an open system, reservoirs must be imposed phenomenologically without any description in the context of quantum mechanics.

Adiabatic reduction of a model of stochastic gene expression with jump Markov process [PDF]
Journal of Mathematical Biology, 2013 This paper considers adiabatic reduction in a model of stochastic gene expression with bursting transcription considered as a jump Markov process. In this model, the process of gene expression with auto-regulation is described by fast/slow dynamics.

Early Developments in the Theory of the Saturated Adiabatic Process [PDF]
, 1963 A study of the history of the early developments in the theory of the saturated adiabatic process reveals that the first quantitative formulation of both the dry- and the saturated-adiabatic cooling rates were given by the British physicist, William ...

Adiabatic theorem for classical stochastic processes [PDF]
Journal of Physics A: Mathematical and TheoreticalAbstract We apply adiabatic theorems developed for quantum mechanics to stochastic annealing processes described by the classical master equation with a time-dependent generator. When the instantaneous stationary state is unique and the minimum decay rate g is nonzero, the time-evolved state is basically relaxed to the instantaneous ...

Discretized quantum adiabatic process for free fermions and comparison with the imaginary-time evolution [PDF]
, 2020 Motivated by recent progress of quantum technologies, we study a discretized quantum adiabatic process for a one-dimensional free fermion system described by a variational wave function, i.e., a parametrized quantum circuit. The wave function is composed
