Production of matter in the universe via after-GUT interaction
Production of matter universe via after-GUT interaction
2010/12/21
In this paper we propose a model of the dark energy decay into ordinary and dark matter via the action of some interaction, dubbed as the after-GUT interaction, with the mass scale between the electro...
Flavor structure of the baryon-baryon interaction from lattice QCD

2011/1/13
We investigate baryon-baryon (BB) interactions in the 3-flavor full QCD simulations with degenerate quark masses for all flavors. The BB potentials in the orbital S-wave are extracted from the Nambu-B...
Charmonium-nucleon interaction from lattice QCD with a relativistic heavy quark action
Charmonium-nucleon interaction lattice QCD relativistic heavy quark action
2011/1/13
Detailed information of the low-energy interaction between the charmonia (hc and J=y) and the
nucleon is indispensable for exploring the formation of charmonium bound to nuclei. In order
to investig...
Spinon Phonon Interaction and Ultrasonic Attenuation in Quantum Spin Liquids
Spinon Phonon Interaction Ultrasonic Attenuation Quantum Spin Liquids
2010/11/25
Several experimental candidates for quantum spin liquids have been discovered in the past few
years which appear to support gapless fermionic S = 1 2 excitations called spinons. The spinons may form ...

We investigate baryon-baryon (BB) interactions in the 3-flavor full QCD simulations with degenerate quark masses for all flavors. The BB potentials in the orbital S-wave are extracted from the Nambu-B...
Gamma-rays from SS~433 and its interaction with the W50 nebula
Gamma-rays observations — binaries general — X-rays binaries — stars
2010/11/12
We investigate the production of gamma-rays in the inner regions of SS 433 and in its interaction between its jets and the W50 nebula. We estimate the VHE emission that can be generated within the jet...

Spin waves magnetic quantum wells Coulomb interaction
2010/11/24
We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work,
we introduce equ...
Edge states in two-dimensional electron gas with heterogeneous spin-orbit interaction
Edge states two-dimensional electron gas heterogeneous spin-orbit interaction
2010/11/23
We show that edge states similar to those known for topological insulators exist in two-dimensional electron system with one-band spectrum in the presence of heterogeneous spin-orbit interaction (SOI)...
Effect of Hydrogen Bonding Interaction on the Properties of Caprolactam-Modified Casein/Waterborne Polyurenthane Composite
Hydrogen Bonding Interaction Modified Casein Waterborne Polyurethane (WPU)
2011/12/15
Caprolactam modified casein(CA-CPL) was prepared by using casein and caprolactam firstly. Caprolactam modified casein/waterborne polyurethane composite (CA-CPL/WPU) was prepared from CA-CPL and WPU. E...
Tails of the Unexpected: The Interaction of an Isothermal Shell with a Cloud
hydrodynamics – ISM bubbles – planetary nebulae general – planetary nebulae individual NGC 7293
2010/11/15
A new mechanism for the formation of cometary tails behind dense clouds or globules is discussed. Numerical hydrodynamical models show that when a dense shell of swept-up matter overruns a cloud, mate...
Electronic structure of pristine and K-doped solid picene: Non-rigid-band change and its implication for electron-intramolecular-vibration interaction
Electronic structure of pristine K-doped solid picene: Non-rigid-band change electron-intramolecular-vibration interaction
2010/11/19
We use photoemission spectroscopy to study electronic structures of pristine and K-doped
solid picene. The valence band spectrum of pristine picene consists of three main features
with no state at t...
Tenfold enhancement of MeV Proton generation by a moderate ultra-short laser interaction with H2O nano-wire targets

We report a transport study of ultrathin Bi2Se3 topological insulators with thickness from
one quintuple layer to six quintuple layers grown by molecular beam epitaxy. At low
temperatures, the film ...

2011/1/7
A new microscopic nucleon-nucleon (NN) interaction has been derived for the first time from
the popular relativistic mean field theory (RMFT) Lagrangian. The NN interaction so obtained
remarkably re...

Interaction picture Haag`s theorem Space-time lattice
2011/1/14
Haag`s theorem states that if a quantum field theory is Lorentz invariant and irreducible, there is no interaction picture.
