Accessing the non-equal-time commutators of a trapped ion
F. Krumm, W. Vogel
The vibronic dynamics of a trapped ion in the resolved-sideband regime can be described by the explicitly time-dependent nonlinear Jaynes-Cummings model. It is shown that the expec…
Quantum effects of operator time ordering in the nonlinear Jaynes-Cummings model
Tobias Lipfert, Fabian Krumm, Mikhail I. Kolobov +1
Recently, in [Phys. Rev. A 97, 043806 (2018)], the detuned and nonlinear Jaynes-Cummings model describing the quantized motion of a trapped ion was introduced and its corresponding…
Anomalous quantum correlations in the motion of a trapped ion
Fabian Krumm, Werner Vogel
In a previous paper (Krumm and Vogel 2018 Phys. Rev. A 97, 043806) we presented a method to solve the nonlinear Jaynes-Cummings dynamics, describing the quantized motion of a trapp…
Time-dependent nonlinear Jaynes-Cummings dynamics of a trapped ion
Fabian Krumm, Werner Vogel
In quantum interaction problems with explicitly time-dependent interaction Hamiltonians, the time ordering plays a crucial role for describing the quantum evolution of the system u…
Time-dependent quantum correlations in phase space
Fabian Krumm, Werner Vogel, Jan Sperling
General quasi-probabilities are introduced to visualize time-dependent quantum correlations of light in phase space. They are based on the generalization of the Glauber-Sudarshan P…
Multitime correlation functions in nonclassical stochastic processes
F. Krumm, J. Sperling, W. Vogel
A general method is introduced for verifying multitime quantum correlations through the characteristic function of the time-dependent P functional that generalizes the Glauber-Suda…
