Dynamics of magnetophoresis in dilute magnetic fluids
Abstract Experimental and theoretical studies were carried out to investigate the spatial distribution of colloidal particles in magnetic fluids formed under the influence of magnetophoresis and gradient diffusion in strong magnetic fields. The...

Wang–Landau study of the 2d random-bond Blume–Capel model
Abstract We study, via a two-stage Wang–Landau (WL) strategy, the random-bond version of the square lattice ferromagnetic Blume–Capel (BC) model, in both the first- and second-order phase transition regimes of the pure model. The second-order phase...

Modified Dirac equation with Lorentz invariance violation and its solutions for particles in an external magnetic field
Abstract The second-order modified Dirac equation leading to the modified dispersion relation due to the Lorentz invariance violation corrections is suggested. The equation is formulated in the 16-component first-order form. I have obtained the...

Small extra dimensions from the interplay of gauge and supersymmetry breaking
Abstract Higher-dimensional theories provide a promising framework for unified extensions of the supersymmetric Standard Model. Compactifications to four dimensions often lead to U ( ...

Double lepton polarization in decay in the Standard Model with fourth generations scenario
Abstract This study investigates the influence of the fourth generation quarks on the double lepton polarizations in Λ b ...

Geometric transitions and dynamical SUSY breaking
Abstract We show that the physics of D-brane theories that exhibit dynamical SUSY breaking due to stringy instanton effects is well captured by geometric transitions, which recast the nonperturbative superpotential as a classical flux...

A note on local GUT models in F-theory
Abstract We construct non-minimal GUT local models in the F-theory configuration. The gauge group on the bulk G S is one...

Modelisation of the Rheological Behavior of Viscoelastic Materials Using the Fractional Derivatives and Transfer Technique
Abstract The aim of this research is to develop a fractional mathematical model of α-order (α), by studying accurately the rheological behavior of viscoelastic materials by mathematical modelisation using derivative and integration fractional...

The characteristic target-pattern regional ore zonality of the Nanling region, China (I)
Abstract By applying the ‘theory of synchronization’ from the science of complexity to studying the regional regularity of ore formation within the Nanling region of southern China, a characteristic target-pattern regional ore zonality has been...

SUGRA hybrid inflation with shift symmetry
Abstract We propose a solution to the η-problem in supergravity (SUGRA) hybrid inflation using a Nambu–Goldstone-like shift symmetry within a new class of models. The flatness of the tree-level inflaton potential is ensured by shift symmetry...

Quantum Regge Calculus of Einstein–Cartan theory
Abstract We study the Quantum Regge Calculus of Einstein–Cartan theory to describe quantum dynamics of Euclidean space–time discretized as a 4-simplices complex. Tetrad field e ...

Entropy corrections for Schwarzschild black holes
Abstract Recently it is shown that the Bekenstein–Hawking entropy for black holes receives logarithmic corrections due to thermodynamic fluctuations. Schwarzschild black hole which possesses a negative specific heat is thermodynamically unstable, so ...

A realistic extension of gauge-mediated SUSY-breaking model with superconformal hidden sector
Abstract The sequestering of supersymmetry (SUSY) breaking parameters, which is induced by superconformal hidden sector, is one of the solutions for the μ / ...

Green–Schwarz, Nambu–Goto actions, and Cayley's hyperdeterminant
Abstract It has been recently shown that Nambu–Goto action can be re-expressed in terms of Cayley's hyperdeterminant with the manifest SL ( 2 , ...

Logarithmic scaling for height variables in the Abelian sandpile model
Abstract We report on the exact computation of the scaling form of the 1-point function, on the upper-half plane, of the height 2 variable in the two-dimensional Abelian sandpile model. By comparing the open versus the closed boundary condition, we...

A new model of agegraphic dark energy
Abstract In this note, we propose a new model of agegraphic dark energy based on the Károlyházy relation, where the time scale is chosen to be the conformal time η of the Friedmann–Robertson–Walker (FRW) universe. We find that in the...
