Dynamics of Entanglement in Jaynes–Cummings Nodes with Nonidentical Qubit-Field Coupling Strengths
Entropy, 2017 How to analytically deal with the general entanglement dynamics of separate Jaynes–Cummings nodes with continuous-variable fields is still an open question, and few analytical approaches can be used to solve their general entanglement dynamics ...

Reconstruction of SU(1,1) States [PDF]
, 2000 We show how group symmetries can be used to reconstruct quantum states. In our scheme for SU(1,1) states, the input field passes through a non-degenerate parametric amplifier and one measures the probability of finding the output state with a certain ...

Entanglement generated by the dispersive interaction: The dressed coherent state [PDF]
, 2015 In the dispersive regime of qubit-cavity coupling, classical cavity drive populates the cavity, but leaves the qubit state unaffected. However, the dispersive Hamiltonian is derived after both a frame transformation and an approximation.

Quantum Fluctuations in Vacuum Energy: Cosmic Inflation as a Dynamical Phase Transition
Universe, 2022 A variety of models of inflation in the early Universe have been proposed and applied to describe successfully the origin of all possible structures in the Universe.

Spin squeezing in nonlinear spin coherent states
, 2001 We introduce the nonlinear spin coherent state via its ladder operator formalism and propose a type of nonlinear spin coherent state by the nonlinear time evolution of spin coherent states.

Characterizing Quantum Effects in Optically Induced Nanowire Self-Oscillations: Coherent Properties
Photonics, 2021 Mechanical properties of metallic-nanowire self-oscillations are investigated through a coherent-state analysis. We focus on elucidating the time behavior of quantum energy in such oscillations, in addition to the analysis of fluctuations, evolution of ...

Weak Coherent State Path Integrals
, 2003 Weak coherent states share many properties of the usual coherent states, but do not admit a resolution of unity expressed in terms of a local integral. They arise e.g. in the case that a group acts on an inadmissible fiducial vector.

Coherent states of non-Hermitian quantum systems [PDF]
, 2006 We use the Gazeau-Klauder formalism to construct coherent states of non-Hermitian quantum systems. In particular we use this formalism to construct coherent state of a PT symmetric system. We also discuss construction of coherent states following Klauder'
