Landau-Zener extension of the Tavis-Cummings model: Structure of the solution

  title={Landau-Zener extension of the Tavis-Cummings model: Structure of the solution},
  author={Chen Sun and Nikolai A. Sinitsyn},
  journal={Physical Review A},
We explore the recently discovered solution of the driven Tavis-Cummings model (DTCM). It describes interaction of an arbitrary number of two-level systems with a bosonic mode that has linearly time-dependent frequency. We derive compact and tractable expressions for transition probabilities in terms of the well-known special functions. In this form, our formulas are suitable for fast numerical calculations and analytical approximations. As an application, we obtain the semiclassical limit of…

Algebraic approach to the Tavis-Cummings model with three modes of oscillation

We study the Tavis-Cummings model with three modes of oscillation by using four different algebraic methods: the Bogoliubov transformation, the normal-mode operators, and the tilting transformation

Berry phase of the Tavis-Cummings model with three modes of oscillation

In this paper we develop a general method to obtain the Berry phase of time-dependent Hamiltonians with a linear structure given in terms of the $SU(1,1)$ and $SU(2)$ groups. This method is based on

The degenerate Landau–Zener–Majorana–Stückelberg model consists of two degenerate energy levels whose energies vary with time and in the presence of an interaction which couples the states of the two

Matrix diagonalization and exact solution of the k-photon Jaynes–Cummings model

Abstract We study and exactly solve the two-photon and k-photon Jaynes–Cummings models by using a novelty algebraic method. This algebraic method is based on the Pauli matrices realization and the

Integrable Time-Dependent Quantum Hamiltonians.

This work forms a set of conditions under which the nonstationary Schrödinger equation with a time-dependent Hamiltonian is exactly solvable analytically, and provides a strategy to incorporate time dependence into various quantum integrable models while maintaining their integrability.

Detuning-induced robustness of a three-state Landau-Zener model against dissipation

A three-state system subjected to a time-dependent Hamiltonian whose bare energies undergo one or more crossings, depending on the relevant parameters, is considered, also taking into account the

Landau-Zener-Stückelberg interferometry in PT -symmetric non-Hermitian models

We systematically investigate the non-Hermitian generalisations of the Landau-Zener (LZ) transition and the Landau-Zener-Stuckelberg (LZS) interferometry. The LZ transition probabilities, or band

A large class of solvable multistate Landau–Zener models and quantum integrability

The concept of quantum integrability has been introduced recently for quantum systems with explicitly time-dependent Hamiltonians (Sinitsyn et al 2018 Phys. Rev. Lett. 120 190402). Within the

Landau-Zener transition in a two-level system coupled to a single highly excited oscillator

Two-level system strongly coupled to a single resonator mode (harmonic oscillator) is a paradigmatic model in many subfields of physics. We study theoretically the Landau-Zener transition in this

    The reason for this difference is that, in our case, bosons can occupy only a fixed number n of energy levels of the single particle spectrum instead of the unbound spectrum in Ref

      There is a difference of the partition function in Eq. (21) from the partition function of free bosons in Eq. (23) of Ref
