Quantum singular oscillator as a model of two-ion trap: an amplification of transition probabilities due to small time variations of the binding potential
V. V. Dodonov, V. I. Man'ko, L. Rosa
Following the paper by M. Combescure [Ann. Phys. (NY) 204, 113 (1990)], we apply the quantum singular time dependent oscillator model to describe the relative one dimensional motio…
A Nonlinear Dynamics and New Quasiclassical Solutions for a Class of Quantum Coupled Systems
Valery P. Karassiov
Hamiltonians of a wide-spread class of strongly coupled quantum system models are expressed as nonlinear functions of generators. It enables us to use the formalism…
Interference effects in f-deformed fields
Stefano Mancini, Paolo Tombesi, Vladimir I. Man'ko
We show how the introduction of an algeabric field deformation affects the interference phenomena. We also give a physical interpretation of the developed theory.
Different realizations of tomographic principle in quantum state measurement
Stefano Mancini, Paolo Tombesi, Vladimir I. Man'ko
We establish a general principle for the tomographic approach to quantum state reconstruction, till now based on a simple rotation transformation in the phase space, which allows u…
Continuous Quantum Monitoring of Position of Nonlinear Oscillators
Michael B. Mensky, Roberto Onofrio, Carlo Presilla
Application of the path-integral approach to continuous measurements leads to effective Lagrangians or Hamiltonians in which the effect of the measurement is taken into account thr…
Optimal Monitoring of Position in Nonlinear Quantum Systems
Michael B. Mensky, Roberto Onofrio, Carlo Presilla
We discuss a model of repeated measurements of position in a quantum system which is monitored for a finite amount of time with a finite instrumental error. In this framework we re…
How to visualize a quantum transition of a single atom
J. Audretsch, M. Mensky, V. Namiot
The previously proposed visualization of Rabi oscillations of a single atom by a continuous fuzzy measurement of energy is specified for the case of a single transition between lev…
Beyond the Standard "Marginalizations" of Wigner Function
Stefano Mancini, Paolo Tombesi, Vladimir I. Man'ko
We discuss the problem of finding "marginal" distributions within different tomographic approaches to quantum state measurement, and we establish analytical connections among them.
Asymptotic State Vector Collapse and QED Nonequivalent Representations
S. N. Mayburov
The state vector evolution in the interaction of measured pure state with the collective quantum system or the field is analyzed in a nonperturbative QED formalism. As the model ex…
Polynomial Lie Algebras and Associated Pseudogroup Structures in Composite Quantum Models
Valery P. Karassiov
Polynomial Lie (super)algebras are introduced via -invariant polynomial Jordan maps in quantum composite models with Hamiltonians having invariance groups $G_{i…
Time-Dependent Invariants for Dirac Equation and Newton-Wigner Position Operator
V. I. Man'ko, R. V. Mendes
For Dirac equation, operator-invariants containing explicit time-dependence in parallel to known time-dependent invariants of nonrelativistic Schrödinger equation are introduced an…
