On Evolution of Coherent States as Quantum Counterpart of Classical Dynamics
Lasha Berezhiani, Michael Zantedeschi
Quantum dynamics of coherent states is studied within quantum field theory using two complementary methods: by organizing the evolution as a Taylor series in elapsed time and by pe…

Breaking BEC: Quantum evolution of unstable condensates
A. Kovtun, M. Zantedeschi
In this work we numerically explore the quantum behavior of a classically unstable relativistic Bose-Einstein condensate (BEC). The main goal is to study the phenomenon of so-calle…

Breaking BEC
A. Kovtun, M. Zantedeschi
In this work quantum corrections to the classical evolution of a relativistic scalar condensate are studied. The problem is approached by means of two different perturbative approa…
