Realization of symmetric sharing of entanglement in semiconductor microcrystallites coupled by a cavity field
Yu-xi Liu, Adam Miranowicz, Masato Koashi +1
The entanglement of excitonic states in a system of spatially separated semiconductor microcrystallites is investigated. The interaction among the different microcrystallites i…
Limits of noise squeezing in Kerr effect
J. Bajer, A. Miranowicz, R. Tanas
It is well known that the optical Kerr effect can be a source of highly squeezed light, however the analytical limit of the noise suppression has not been found yet. The process is…
Neel probability and spin correlations in some nonmagnetic and nondegenerate states of hexanuclear antiferromagnetic ring Fe6: Application of algebraic combinatorics to finite Heisenberg spin systems
Wojciech Florek, Sylwia Bucikiewicz
The spin correlations ω^z_r, r=1,2,3, and the probability p_N$ of finding a system in the Neel state for the antiferromagnetic ring Fe(III)6 (the so-called `small ferric wheel') ar…
Two-dimensional electron gas in a periodic potential and external magnetic field: states of pairs and three-particle systems
Wojciech Florek
The group-theoretical classification of states of identical particle pairs is presented. Then obtained states are coupled with those of an antiparticle to construct states of a thr…
On the Superconductivity in the Induced Pairing Model
R. Micnas, S. Robaszkiewicz, A. Bussmann-Holder
The two component model of coexisting local electron pairs and itinerant fermions coupled via charge exchange mechanism, which mutually induces superconductivity in both subsystems…
Synchronization in coupled map lattices as an interface depinning
Adam Lipowski, Michel Droz
We study an SOS model whose dynamics is inspired by recent studies of the synchronization transition in coupled map lattices (CML). The synchronization of CML is thus related with…
