Measurements of nuclear $\gamma$-ray line emission in interactions of protons and $\alpha$ particles with N, O, Ne and Si
Measurements of nuclear $\gamma$-ray line emission interactions of protons $\alpha$ particles with N, O, Ne and Si
2011/1/4
$\gamma$-ray production cross sections have been measured in proton irradiations of N, Ne and Si and $\alpha$-particle irradiations of N and Ne. In the same experiment we extracted also line shapes fo...
Observation of exchange Coulomb interactions in the quantum Hall state at nu=3
exchange Coulomb interactions quantum Hall state
2010/11/19
Coulomb exchange interactions of electrons in the = 3 quantum Hall state are determined from
two inter-Landau level spin-flip excitations measured by resonant inelastic light scattering. The two co...
Strong Interactions of Single Atoms and Photons near a Dielectric Boundary
Interactions Single Atoms Dielectric Boundary
2010/11/8
Modern research in optical physics has achieved quantum control of strong interactions between a single atom and one photon within the setting of cavity quantum electrodynamics (cQED). However, to mov...
Aerosol effects on ice clouds: can the traditional concept of aerosol indirect effects be applied to aerosol-cloud interactions in cirrus clouds?
Aerosol effects ice clouds aerosol indirect effects aerosol-cloud interactions cirrus clouds
2010/11/29
Cirrus clouds cover approximately 20–25% of the globe and thus play an important role in the Earth's radiation budget. Therefore the effect of aerosols on cirrus clouds can have a substantial impact o...
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...
We discuss possible relationships between geometric and topological in-teractions on one side and physical interactions on the other side. This paper is a follow up of [2].

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...
