Effective dissipative dynamics for polarized photons

Abstract

In the framework of open quantum systems, the propagation of polarized photons can be effectively described using quantum dynamical semigroups. These extended time-evolutions induce irreversibility and dissipation. Planned, high sensitive experiments, both in the laboratory and in space, will be able to put stringent bounds on these non-standard effects.

Damped harmonic oscillators in the holomorphic representation

“…[1][2][3][13][14][15][16][17][18][19][20] For the damped oscillator described by the evolution equation (2.10), this request can not be fulfilled in general, if one insists on the existence of a well-behaved large-time equilibrium limit. The explicit evaluation of S B ≡ S[ρ B ] is simplified by noticing that to the representation kernel (2.17) there corresponds the operator Ansatz: 27) where the parameters A and B are related to x and y of (2.17) through the relations:…”

“…Non-standard low energy effects accompanied by loss of quantum coherence are in fact expected to appear as a consequence of gravitational quantum fluctuations at Planck's scale. [12] Detailed analysis of these effects have been performed in the system of neutral mesons, [13][14][15][16] in neutron interferometry, [17] neutrino oscillations, [18] and in the propagation of polarized photons; [19,20] the outcome of these investigations is that present and future elementary particle experiments will likely put stringent bounds on these non-standard dissipative phenomena.…”

Open Quantum Dynamics: Complete Positivity and Entanglement

“…21 These effects produce distinctive signatures in the behaviour of selected physical observables, allowing direct experimental testing (for specific treatments and further details, see Refs. [22][23][24][25][26][27][28][29][30][31][32]). …”

Planck-scale dissipative effects in atom interferometry

“…Despite of this, they can be in the reach of various interferometric devices. Indeed, detailed investigations involving different elementary particle systems (neutral mesons [25,26], neutrons [27], photons [28], and neutrinos [29]) have shown that present and future experiments might soon reach the sensitivity required to detect the new, non-standard phenomena.…”
