Coupling modifies the quantum fluctuations of entangled oscillators
Roberto Baginski B. Santos, Vinicius S. F. Lisboa
Coupled oscillators are among the simplest composite quantum systems in which the interplay of entanglement and interaction may be explored. We examine the effects of coupling on f…
Non-Hermitian Model for Asymmetrical Tunneling
Roberto Baginski B. Santos, Vinícius Rocha da Silva
We present a simple non-hermitian model to describe the phenomenon of asymmetric tunneling between two energy-degenerate sites coupled by a non-reciprocal interaction without dissi…
Non-hermitian model for resonant cavities coupled by a chiral mirror
Roberto Baginski B. Santos
Inspired by a recently observed asymmetry in the transmission of circularly polarized light through a metamaterial, we present a non-hermitian PT-symmetric quantum model to describ…
