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…
Entanglement resonance in the asymmetric quantum Rabi model
Yu-Qing Shi, Lei Cong, Hans-Peter Eckle
We investigate the entanglement features in the interacting system of a quantized optical field and a two-level system which is statically driven, known as the asymmetric quantum R…
Application of polaron picture in the two-qubit quantum Rabi model
Xi-Mei Sun, Lei-Cong, Hans-Peter Eckle +2
The polaron picture is employed to investigate and elucidate the physics of the two-qubit quantum Rabi model, which describes two identical qubits coupled to a common harmonic osci…
A generalization of the quantum Rabi model: exact solution and spectral structure
Hans-Peter Eckle, Henrik Johannesson
We consider a generalization of the quantum Rabi model where the two-level system and the single-mode cavity oscillator are coupled by an additional Stark-like term. By adapting a…
Persistent currents through a quantum impurity: Protection through integrability
Johan Nilsson, H. -P. Eckle, Henrik Johannesson
We consider an integrable model of a one-dimensional mesoscopic ring with the conduction electrons coupled by a spin exchange to a magnetic impurity. A symmetry analysis based on a…
Persistent Currents in the Heisenberg chain with a weak link
T. M. R. Byrnes, R. J. Bursill, H. -P. Eckle +2
The Heisenberg chain with a weak link is studied, as a simple example of a quantum ring with a constriction or defect. The Heisenberg chain is equivalent to a spinless electron gas…
