Memory Burden Effect in Black Holes and Solitons: Implications for PBH
Gia Dvali, Juan Sebastián Valbuena-Bermúdez, Michael Zantedeschi
The essence of the \textit{memory burden} effect is that a load of information carried by a system stabilizes it. This universal effect is especially prominent in systems with a hi…
Perturbative Construction of Coherent States
Lasha Berezhiani, Giordano Cintia, Michael Zantedeschi
The perturbative consistency of coherent states within interacting quantum field theory requires them to be altered beyond the simple non-squeezed form. Building on this point, we…
Dynamics of Confined Monopoles and Similarities with Confined Quarks
Gia Dvali, Juan Valbuena-Bermudez, Michael Zantedeschi
In this work, we study the annihilation of a pair of `t Hooft-Polyakov monopoles due to confinement by a string. We analyze the regime in which the scales of monopoles and strings…
Vortices in Black Holes
Gia Dvali, Florian Kuhnel, Michael Zantedeschi
We argue that black holes admit vortex structure. This is based both on a graviton-condensate description of a black hole as well as on a correspondence between black holes and gen…
Background Field Method and Initial-Time Singularity for Coherent States
Lasha Berezhiani, Giordano Cintia, Michael Zantedeschi
The background field method is adopted for studying the dynamics of coherent states within an interacting scalar field theory. Focusing on a coherent state that corresponds to the…
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…
