Are the ground states of randomly interacting bosons random?
Charles White, Alexander Volya, Declan Mulhall +1
Bosonic degrees of freedom and their emergence as a part of complex quantum many-body dynamics, symmetries, collective behavior, clustering and phase transitions play an important…
Time-dependent relaxation of observables in complex quantum systems
Alexander Volya, Vladimir Zelevinsky
We consider time-dependent relaxation of observables in quantum systems of chaotic and regular type. We show that the spread of the wave function in the Hilbert space is determined…
Exploring quantum dynamics in an open many-body system: Transition to superradiance
Alexander Volya, Vladimir Zelevinsky
We study the dynamics of a complex open quantum many-body system. The coupling to external degrees of freedom can be viewed as a coupling to a radiation field, to continuum states…
