Symmetry-breaking oscillations in membrane optomechanics
C. Wurl, A. Alvermann, H. Fehske
We study the classical dynamics of a membrane inside a cavity in the situation where this optomechanical system possesses a reflection symmetry. Symmetry breaking occurs through su…
Nonclassical light from few emitters in a cavity
D. Pagel, A. Alvermann, H. Fehske
We study the characteristics of the light generated by few emitters in a cavity at strong light-matter coupling. By means of the Glauber -function we can identify clearly…
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…
Equilibration and thermalization of the dissipative quantum harmonic oscillator in a non-thermal environment
D. Pagel, A. Alvermann, H. Fehske
We study the dissipative quantum harmonic oscillator with general non-thermal preparations of the harmonic oscillator bath. The focus is on equilibration of the oscillator in the l…
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…
Variational discrete variable representation for excitons on a lattice
A. Alvermann, P. B. Littlewood, H. Fehske
We construct numerical basis function sets on a lattice, whose spatial extension is scalable from single lattice sites to the continuum limit. They allow us to compute small and la…
