On the Occurrence of a Phase Transition in Atomic Systems
Luca Gamberale, Daniele Garbelli
We present a simple argument confirming the spontaneous quantum condensation of an electromagnetic field in matter in the case of a multi-level atomic system coupled to a single-mo…
Numerical Simulations Unveil Superradiant Coherence in a Lattice of Charged Quantum Oscillators
L. Gamberale, G. Modanese
A system of charged oscillators interacting with the electromagnetic field, spatially confined in a 3D lattice of sub-wavelength dimension, can condense into a superrad…
Neutron Production via Electron Capture by Coherent Protons
Luca Gamberale
I consider coherent vibrational states of the quantum plasmas formed by the conduction electrons and protons inside a metal hydride. Such states can interact coherently through wea…
Coherent Plasma in a Lattice
L. Gamberale, G. Modanese
We present a fully second-quantized calculation showing the emergence of spontaneous coherent configurations of the electromagnetic field in interaction with charged bosons in a re…
External magnetic fields in gauge theories
L. Gamberale, G. Preparata, She-Sheng XUE
A general discussion is presented of the response of a gauge-field system to external magnetic fields, in the light of a theorem due to S. Elitzur. As a result a natural understand…
