Unavoidability of nonclassicality loss in PT-symmetric systems
Jan Perina, Adam Miranowicz, Joanna K. Kalaga +1
We show that the loss of nonclassicality (including quantum entanglement) cannot be compensated by the (incoherent) amplification of PT-symmetric systems. We address this problem b…
Nonclassical light at exceptional points of a quantum PT-symmetric two-mode system
Jan Perina, Antonin Luks, Joanna K. Kalaga +2
A two-mode optical parity-time (PT) symmetric system, with gain and damping, described by a quantum quadratic Hamiltonian with additional small Kerr-like nonlinear terms, is analyz…
Interaction of the hydrogen molecule with the environment: stability of the system
I. A. Wrona, M. W. Jarosik, R. Szczȩśniak +3
We study the stability of the hydrogen molecule interacting with the environment according to the balanced gain and loss energy scheme. We determined the properties of the molecule…
Long-time joint spectra and entanglement of two photoelectrons originating in interacting auto-ionization systems
Jan Perina, A. Luks, W. Leonski
Two auto-ionization systems in a stationary optical field mutually interacting via the dipole-dipole interaction are considered. Their evolution is analytically found. Joint spectr…
Nonlinear coupler operating on Werner-like states - entanglement creation, its enhancement and preservation
A. Kowalewska-Kudłaszyk, W. Leoński
We discuss a model of two nonlinear Kerr-like oscillators, mutually coupled and excited by parametric process. We show that the system's evolution, starting from Werner-like states…
Kicked nonlinear quantum scissors and entanglement generation
A. Kowalewska-Kudłaszyk, W. Leoński, T. Dung Nguyen +1
We consider a nonlinear coupler with two Kerr-like oscillators mutually coupled by continuous linear interaction and excited by a series of ultra-short external pulses. We show tha…
