Dark energy and dark matter interaction in light of the second law of thermodynamics / Cárdenas, Víctor H. ; Grandón, Daniela ; Lepe, Samuel
In the context of thermodynamics we discuss the way inevitable emerge an interaction between dark components, and in this way, provide a mechanism to understand the limits of the LCDM model and the class of interaction models between dark components. [...]

Cosmological dynamics of the general non-canonical scalar field models / Dutta, Jibitesh ; Khyllep, Wompherdeiki ; Zonunmawia, Hmar
We extend the investigation of cosmological dynamics of the general non-canonical scalar field models by dynamical system techniques for a broad class of potentials and coupling functions. [...]

The unphysical character of minimally coupled dark energy fluids / Duarte, Ronaldo C. ; Barboza, Edésio M. ; Abreu, Everton M. C. ; Neto, Jorge Ananias
It is well known that, in the context of general relativity, an unknown kind of matter that must violate the strong energy condition is required to explain the current accelerated phase of expansion of the Universe. [...]

On sign-changeable interaction in FLRW cosmology / Arevalo, Fabiola ; Cid, Antonella ; Chimento, Luis P. ; Mella, Patricio
We investigate an interacting two-fluid model in a spatially flat Friedmann–Lemaître–Robertson–Walker (FLRW) Universe, when the energy transfer between these two dark components is produced by a factorizable nonlinear sign-changeable interaction depending linearly on the energy density and quadratically on the deceleration parameter.

Analysis of black hole thermodynamics with a new higher order generalized uncertainty principle / Hassanabadi, Hassan ; Maghsoodi, Elham ; Chung, Won Sang
This research explores a unified expression for the black hole thermodynamics in the presence of a special generalized uncertainty principle (GUP). [...]

Thermodynamics and weak cosmic censorship conjecture in extended phase spaces of anti-de Sitter black holes with particles’ absorption / Chen, Deyou
The thermodynamics and weak cosmic censorship conjecture in extended phase spaces of charged anti-de Sitter black holes describing the massive gravity are investigated by the absorptions of the scalar particle and fermion. [...]

Electromagnetic dipole moments and time reversal violating interactions for high energy charged baryons in bent crystals at LHC / Baryshevsky, V. G.
Spin precession of channelled particles in bent crystals at the LHC gives unique possibility for measurements of constants determining T-odd, P-odd (CP) violating interactions and P-odd, T-even interactions of charm, beauty and strange charged baryons with electrons and nucleus (nucleons), similarly to the possibility of measuring their electric and magnetic moments.
