Effective dissipation and turbulence in spectrally truncated euler flows.

Physical review letters

Cichowlas C, Bonaïti P, Debbasch F, Brachet M.
PMID: 16486361
Phys Rev Lett. 2005 Dec 31;95(26):264502. doi: 10.1103/PhysRevLett.95.264502. Epub 2005 Dec 22.

A new transient regime in the relaxation towards absolute equilibrium of the conservative and time-reversible 3D Euler equation with a high-wave-number spectral truncation is characterized. Large-scale dissipative effects, caused by the thermalized modes that spontaneously appear between a transition...

Dirac Spatial Search with Electric Fields.

Entropy (Basel, Switzerland)

Zylberman J, Debbasch F.
PMID: 34828139
Entropy (Basel). 2021 Oct 31;23(11). doi: 10.3390/e23111441.

Electric Dirac quantum walks, which are a discretisation of the Dirac equation for a spinor coupled to an electric field, are revisited in order to perform spatial searches. The Coulomb electric field of a point charge is used as...

Nonlinear optical Galton board: Thermalization and continuous limit.

Physical review. E, Statistical, nonlinear, and soft matter physics

Di Molfetta G, Debbasch F, Brachet M.
PMID: 26565320
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Oct;92(4):042923. doi: 10.1103/PhysRevE.92.042923. Epub 2015 Oct 28.

The nonlinear optical Galton board (NLOGB), a quantum walk like (but nonlinear) discrete time quantum automaton, is shown to admit a complex evolution leading to long time thermalized states. The continuous limit of the Galton board is derived and...

Quantum walk hydrodynamics.

Scientific reports

Hatifi M, Di Molfetta G, Debbasch F, Brachet M.
PMID: 30814623
Sci Rep. 2019 Feb 27;9(1):2989. doi: 10.1038/s41598-019-40059-x.

A simple Discrete-Time Quantum Walk (DTQW) on the line is revisited and given an hydrodynamic interpretation through a novel relativistic generalization of the Madelung transform. Numerical results show that suitable initial conditions indeed produce hydrodynamical shocks and that the...

Tacrine-induced Reactive Oxygen Species in a Human Liver Cell Line: The Role of Anethole Dithiolethione as a Scavenger.

Toxicology in vitro : an international journal published in association with BIBRA

Osseni RA, Debbasch C, Christen MO, Rat P, Warnet JM.
PMID: 20654534
Toxicol In Vitro. 1999 Aug-Oct;13(4):683-8. doi: 10.1016/s0887-2333(99)00050-8.

The mechanisms leading to tacrine (THA) hepatotoxic effects are not yet fully understood. Reactive oxygen species (ROS) overproduction and intracellular reduced glutathione (GSH) depletion are common mechanisms involved in drug toxicity. The aim of this study was to investigate,...
