Quantum phase transition in the multi-mode Dicke model
Denis Tolkunov, Dmitry Solenov
An investigation of the quantum phase transition in both discrete and continuum field Dicke models is presented. A series of anticrossing features following the criticality is reve…

Entanglement and Quantum Noise Due to a Thermal Bosonic Field
Dmitry Solenov, Denis Tolkunov, Vladimir Privman
We analyze the indirect exchange interaction between two two-state systems, e.g., spins 1/2, subject to a common finite-temperature environment modeled by bosonic modes. The enviro…

Stability of quantum breathers
L. S. Schulman, D. Tolkunov, E. Mihokova
Using two methods we show that a quantized discrete breather in a 1-D lattice is stable. One method uses path integrals and compares correlations for a (linear) local mode with tho…
