Final state interactions and CP violation in B+- --> pi+- pi-+ pi+- decays
Final state interactions CP violation in B+- --> pi+- pi-+ pi+- decays
2011/1/5
We study CP violation and the contribution of the strong pion-pion interactions in the three-body B± →π±π∓π± decays within a quasi two-body QCD factorization approach. The short distance interac...
Quasistationarity in a model of classical spins with long-range interactions
Quasistationarity model of classical spins long-range interactions
2010/11/17
Systems with long-range interactions, while relaxing towards equilibrium, sometimes
get trapped in long-lived non-Boltzmann quasistationary states (QSS) which have lifetimes that
grow algebraically ...
Possible realization of the Exciton Bose Liquid phase in a hard-core boson model with ring-only exchange interactions
Possible realization ring-only exchange interactions
2010/11/17
We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a K1
term acts on 1×1 plaquettes and a K2 term acts on 1×2 and 2×1 plaquettes, with a goal of realizing a no...
Ab initio prediction of ferrimagnetism, exchange interactions and Curie temperatures in Mn2TiZ Heusler compounds
initio prediction of ferrimagnetism Curie temperatures
2010/11/19
The Heusler compounds Mn2TiZ (Z = Al, Ga, In, Si, Ge, Sn, P, As,Sb) are of large interest due to their potential ferrimagnetic properties and high spin polarization. Here, we present calculations of t...
Hyperfine and Zeeman interactions of the $a(1)[^3\Sigma^+_1]$ state of PbO
Hyperfine Zeeman interactions
2010/11/16
The role of the interaction with the nearest electronic state $^3\Sigma^+_{0^-}$ on the hyperfine structure and magnetic properties of the $a(1)[^3\Sigma^+_1]$ state of PbO is assessed. The accountin...
Cosmological evolutions of completely degenerated Fermi-system with the scalar interparticles interactions
Cosmological evolutions of completely degenerated Fermi-system scalar interparticles interactions
2010/12/20
To the moment it has been published many papers devoted to the secondary acceleration of the Universe. In order to solve the problem of the secondary acceleration of the Universe it is often proposed ...
The non-retarded Casimir interaction (van der Waals interaction) between two free standing
graphene sheets as well as between a graphene sheet and a substrate is determined. An exact
analytical expr...
Chiral model for $\bar{K}N$ interactions and its pole content
chiral Lagrangians coupled channels meson-baryon interactions
2011/1/7
We use chirally motivated effective meson-baryon potentials to describe the low energy
¯K N data including the characteristics of kaonic hydrogen. Our results are examined in comparison with oth...
Non-perturbative predictions for cold atom Bose gases with tunable interactions
Non-perturbative predictions cold atom Bose gases tunable interactions
2011/1/7
We derive a theoretical description for dilute Bose gases as a loop expansion in terms of composite- eld propagators by rewriting the Lagrangian in terms of auxiliary elds related to the normal and a...
Synchronisation Induced by Repulsive Interactions in a System of van der Pol Oscillators
Synchronisation Repulsive Interactions van der Pol Oscillators
2010/11/22
We consider a system of identical van der Pol oscillators, globally coupled through their
velocities, and study how the presence of competitive interactions affects its synchronisation
properties. W...
Interactions of nanorod particles in the strong coupling regime
Interactions of nanorod particles strong coupling regime
2010/11/18
The plasmon coupling in a nanorod dimer obeys the exponential size dependence according to the Universal Plasmon Ruler Equation. However, it was shown recently that such a model does not hold at short...

Competing magnetic interactions CeNi9-xCoxGe4
2010/11/25
CeNi9Ge4 exhibits outstanding heavy fermion features with remarkable non-Fermiliquid behavior which is mainly driven by single-ion effects. The substitution of Ni by Cu causes a reduction of both, the...

2010/11/25
We study the Langevin dynamics of a ferromagnetic Ginzburg-Landau Hamiltonian with a competing longrange repulsive term in the presence of an external magnetic field. The model is analytically solved ...
