Disentanglement in the macroscopic limit
Eyal Buks
The recently proposed spontaneous disentanglement hypothesis is formulated using a modified Schrödinger equation having an added nonlinear term. The hypothesis is motivated by some…
The spontaneous disentanglement hypothesis and causality
Eyal Buks
The hypothesis that disentanglement spontaneously occurs in quantum systems is motivated by some outstanding issues in the foundations of quantum mechanics. However, for some cases…
Disentanglement by deranking and by suppression of correlation
Eyal Buks
The spontaneous disentanglement hypothesis is motivated by some outstanding issues in standard quantum mechanics, including the problem of quantum measurement. The current study co…
Parametric excitation of a ferrimagnetic sphere resonator
Eyal Buks
The response of a ferrimagnetic sphere resonator to an externally applied parametric excitation is experimentally studied. Measurement results are compared with predictions derived…
A fiber-loop laser with a cooled erbium-doped section
Eyal Buks, Boris A. Malomed
An optical comb featuring an unusual structure has been recently observed in a fiber-loop laser running at cryogenic temperatures. In the present work, the effect of optical polari…
Disentanglement-induced superconductivity
Eyal Buks
The current study is motivated by a difficulty to reconcile between particle number conservation and superconductivity. An alternative modeling, which is based on the hypothesis th…
Disentanglement--induced bistability in a magnetic resonator
Eyal Buks
Multi--stability in the response of a ferrimagnetic spin resonator to an externally applied driving is experimentally studied. The observed multi--stability cannot be derived from…
Spontaneous disentanglement of indistinguishable particles
Eyal Buks
A master equation containing a nonlinear term that gives rise to disentanglement has been recently investigated. In this study, a modified version, which is applicable for indistin…
Disentanglement-induced multistability
Eyal Buks
Multistability cannot be derived from any theoretical model that is based on a monostable master equation. On the other hand, multistability is experimentally-observed in a variety…
Polarimeter optical spectrum analyzer
Eyal Buks
A coherent optical spectrum analyzer is integrated with a rotating quarter wave plate polarimeter. The combined polarimeter optical spectrum analyzer (POSA) allows the extraction o…
Spontaneous disentanglement and thermalisation
Eyal Buks
The problem of quantum measurement can be partially resolved by incorporating a process of spontaneous disentanglement into quantum dynamics. We propose a modified master equation,…
Intermode coupling in a fiber loop laser at low temperatures
Eyal Buks
We experimentally study an unequally-spaced optical comb (USOC), which is generated by a unidirectional fiber loop laser operated at low temperatures. The underlying mechanism resp…
