Time-reversal symmetry breaking and emergence in driven-dissipative Ising models

open access: yesSciPost Physics, 2022
Fluctuation-dissipation relations (FDRs) and time-reversal symmetry (TRS), two pillars of statistical mechanics, are both broken in generic driven-dissipative systems.

Scattering Theory for Open Quantum Systems [PDF]

open access: yes, 2006
Quantum systems which interact with their environment are often modeled by maximal dissipative operators or so-called Pseudo-Hamiltonians. In this paper the scattering theory for such open systems is considered.

Functional Model of Dissipative Fourth Order Differential Operators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
In this paper, maximal dissipative fourth order operators with equal deficiency indices are investigated. We construct a self adjoint dilation of such operators.

Nonself-Adjoint Second-Order Difference Operators in Limit-Circle Cases

open access: yesAbstract and Applied Analysis, 2012
We consider the maximal dissipative second-order difference (or discrete Sturm-Liouville) operators acting in the Hilbert space ℓ2𝑤(ℤ) (ℤ:={0,±1,±2,…}), that is, the extensions of a minimal symmetric operator with defect index (2,2) (in the Weyl ...

Field quantization in inhomogeneous anisotropic dielectrics with spatio-temporal dispersion [PDF]

open access: yes, 2007
A quantum damped-polariton model is constructed for an inhomogeneous anisotropic linear dielectric with arbitrary dispersion in space and time. The model Hamiltonian is completely diagonalized by determining the creation and annihilation operators for ...

Global regularity of 2D MHD equations with almost Laplacian velocity dissipation

open access: yesBoundary Value Problems, 2023
We obtain the global existence and global regularity for the 2D MHD equations with almost Laplacian velocity dissipation, which require the dissipative operators weaker than any power of the fractional Laplacian.

Classical to quantum correspondence in dissipative directed transport [PDF]

open access: yes, 2015
We compare the quantum and classical properties of the (Quantum) Isoperiodic Stable Structures -- (Q)ISSs -- which organize the parameter space of a paradigmatic dissipative ratchet model, i.e. the dissipative modified kicked rotator.

Photothermal Response for the Thermoelastic Bending Effect Considering Dissipating Effects by Means of Fractional Dual-Phase-Lag Theory

open access: yesFractal and Fractional, 2023
We analyze an extension of the dual-phase lag model of thermal diffusion theory to accurately predict the contribution of thermoelastic bending (TE) to the Photoacoustic (PA) signal in a transmission configuration.

Topology by dissipation [PDF]

open access: yes, 2013
Topological states of fermionic matter can be induced by means of a suitably engineered dissipative dynamics. Dissipation then does not occur as a perturbation, but rather as the main resource for many-body dynamics, providing a targeted cooling into a ...
