Correlated electronic states at a ferromagnetic oxide interface
D. Jones, A. Weh, A. Östlin +5
We propose a minimal tight-binding model for the electronic interface layer of the LaAlO/SrTiO heterostructure with oxygen vacancies. In this model, the effective carriers…
Finite-dimensional approximations of generalized squeezing
Sahel Ashhab, Felix Fischer, Davide Lonigro +2
We show unexpected behaviour in simulations of generalized squeezing performed with finite-dimensional truncations of the Fock space: even for extremely large dimension of the stat…
Critical quantum metrology in a stabilized two-photon Rabi model
Zu-Jian Ying, Hang-Hang Han, Bo-Jian Li +2
We investigate a generalized quantum Rabi model (QRM) with two- and four-photon terms with respect to applications for non-linear critical quantum metrology. In the introduced mode…
Exact Floquet solutions in a Parity-Time-Symmetric Rabi Model
M. Baradaran, D. Braak, L. M. Nieto +1
It is shown that a semiclassical Rabi model with parity-time (PT) symmetry has a hidden symmetry and hence possesses quasi-exact solutions. These are located precisely at t…
Critical spectrum of the anisotropic two-photon quantum Rabi model
Jiong Li, Daniel Braak, Qing-Hu Chen
The anisotropic two-photon quantum Rabi model is studied using the Bogoliubov operator approach. The doubly degenerate exceptional states are identified through analytical methods.…
Spectral continuum in the Rabi-Stark model
Daniel Braak, Lei Cong, Hans-Peter Eckle +2
The Rabi-Stark model is a non-linear generalization of the quantum Rabi model including the dynamical Stark shift as a tunable term, which can be realized via quantum simulation on…
