Squeezing of electromagnetic field in a cavity by electrons in Trojan states
Piotr Kochański, Zofia Białynicka-Birula, Iwo Białynicki‐Birula
The notion of the Trojan state of a Rydberg electron, introduced by I. Bialynicki-Birula, M. Kali\ifmmode \acute{n}\else \'{n}\fi{}ski, and J. H. Eberly [Phys. Rev. Lett. 73, 1777 (1994)] is extended to the case of an electromagnetic field quantized in a cavity. The shape of the electronic wave packet describing the Trojan state is practically the same as in the previously studied externally driven system. The fluctuations of the quantized electromagnetic field around its classical value exhibit strong squeezing. The emergence of Trojan states in the cylindrically symmetrical system is attributed to spontaneous symmetry breaking.
