Optomechanical multistability in the quantum regime
C. Schulz, A. Alvermann, L. Bakemeier +1
Classical optomechanical systems feature self-sustained oscillations, where multiple periodic orbits at different amplitudes coexist. We study how this multistability is realized i…
Route to chaos in optomechanics
L. Bakemeier, A. Alvermann, H. Fehske
We establish the emergence of chaotic motion in optomechanical systems. Chaos appears at negative detuning for experimentally accessible values of the pump power and other system p…
Dynamics of the Dicke model close to the classical limit
L. Bakemeier, A. Alvermann, H. Fehske
We study the dynamical properties of the Dicke model for increasing spin length, as the system approaches the limit of a classical spin. First, we describe the emergence of collect…
Quantum phase transition in the Dicke model with critical and non-critical entanglement
L. Bakemeier, A. Alvermann, H. Fehske
We study the quantum phase transition of the Dicke model in the classical oscillator limit, where it occurs already for finite spin length. In contrast to the classical spin limit,…
Collapse-revival dynamics and atom-field entanglement in the non-resonant Dicke model
A. Alvermann, L. Bakemeier, H. Fehske
We consider the dynamics of atomic and field coherent states in the non-resonant Dicke model. At weak coupling an initial product state evolves into a superposition of multiple fie…
