Existence of solution to a nonlinear first-order dynamic equation on time scales

Benaoumeur Bayour, Ahmed Hammoudi, Delfim F. M. Torres

We prove existence of solution to a nonlinear first-order nabla dynamic equation on an arbitrary bounded time scale with boundary conditions, where the right-hand side of the dynam…

Eikonal gluon bremsstrahlung at finite N_c beyond two loops

Yazid Delenda, Kamel Khelifa-Kerfa

We present a general formalism for computing the matrix-element squared for the emission of soft energy-ordered gluons beyond two loops in QCD perturbation theory at finite .…

Complex-valued fractional derivatives on time scales

Benaoumeur Bayour, Delfim F. M. Torres

We introduce a notion of fractional (noninteger order) derivative on an arbitrary nonempty closed subset of the real numbers (on a time scale). Main properties of the new operator…

Properties of dipolar bosonic quantum gases at finite temperatures

Abdelaali Boudjemaa

The properties of ultracold quantum gases of bosons with dipole-dipole interaction is investigated at finite temperature in the frame of the representative ensembles theory. Self-c…

Thermodynamics of a two-dimensional dipolar Bose gas with correlated disorder in the roton regime

Abdelaali Boudjemaa

We sudy the impact of a weak random potential with a Gaussian correlation function on the thermodynamics of a two-dimensional (2D) dipolar bosonic gas. Analytical expressions for t…

Rehabilitating space-times with NUTs

Gérard Clément, Dmitri Gal'tsov, Mourad Guenouche

We revisit the Taub-NUT solution of the Einstein equations without time periodicity condition, showing that the Misner string is still fully transparent for geodesics. In this case…

Spontaneous formation of bright solitons in self-localized impurities in Bose-Einstein condensate

Abdelaali Boudjemaa

We study the formation of bright solitons in the impurity component of Bose-Einstein condensate (BEC)-impurity mixture by using the time-dependent Hartree-Fock-Bogoliubov theory. W…

Superfluidity and Bose-Einstein condensation in a dipolar Bose gas with weak disorder

Abdelaali Boudjemaa

We investigate the properties of a three-dimensional homogeneous dipolar Bose gas in a weak random potential with a Gaussian correlation function at finite temperature. Using the B…

Two-dimensional dipolar bosons with weak disorder

Abdelaali Boudjemaa

We consider two-dimensional dipolar bosonic gas with dipoles oriented perpendicularly to the plane in a weak random potential. We investigate analytically and numerically the conde…

Dipolar Bose gas in a weak isotropic speckle disorder

Abdelaali Boudjemaa

We investigate the properties of a homogeneous dipolar Bose gas in a weak three-dimensional (3D) isotropic speckle disorder at finite temperature. By using the Bogoliubov theory (b…

Non-global logarithms at finite Nc beyond leading order

Kamel Khelifa-Kerfa, Yazid Delenda

We analytically compute non-global logarithms at finite Nc fully up to 4 loops and partially at 5 loops, for the hemisphere mass distribution in e+e- to di-jets to leading logarith…
