Final state interactions in the decay of heavy quarks
Secondary scattering B meson duality
2014/12/23
I discuss some recent results on the systematic behavior of final state rescattering which makes use of the limit of a heavy B meson. The results suggest that soft final state interactions do not disa...
Systematics of soft final-state interactions in B decays
Traditional expectations state interaction inelastic scattering
2014/12/23
By using very general and well established features of soft strong interactions we show, contrary to conventional expectations, that (i) soft final-state interactions (FSI) do not disappear for large ...
BPS force balances via spin-spin interactions
BPS soliton static force balance spin quantum mechanics micro sub zero gravity field model
2014/12/22
We study two systems of BPS solitons in which spin-spin interactions are important in establishing the force balances which allow static, multi-soliton solutions to exist. Solitons in the Israel-Wilso...
We examine the problem of hadronic atom energy shifts using the technique of effective interactions and demonstrate the equivalence with the conventional quantum mechanical approach.
Spin of the M2-brane and spin-spin interactions via probe techniques
Solitary wave rotate super gravity quantitative fermionic zero mode
2014/12/22
The 256-dimensional M2-brane multiplet contains solitons of many different intrinsic spins. Using the broken supersymmetry transformations of the M2-brane, we find supergravity solutions which explici...
In recent years it has been realized that effective interactions—those valid over a limited range of energy-momentum—are often preferable even when more complete theories are available. We shall here ...
Quaternionic vector coherent states for spin-orbit interactions
Quaternionic vector coherent states spin-orbit interactions Mathematical Physics
2012/4/23
This work addresses the study of two-dimensional electron gas in a perpendicular magnetic field in the presence of both Rashba and Dresselhaus spin-orbit (SO) interactions, with effective Zeeman coupl...
Running coupling in electroweak interactions of leptons from f(R)-gravity with torsion
Running coupling electroweak interactions leptons f(R)-gravity with torsion
2012/2/23
The f(R)-gravitational theory with torsion is considered for one family of leptons; it is found that the torsion tensor gives rise to interactions having the structure of the weak forces while the int...
A derivation of the Breit equation from Barut's covariant formulation of electrodynamics in terms of direct interactions
Breit equation Barut's covariant formulation Quantum Physics High Energy Physics - Theory
2011/10/10
Abstract: We study Barut's covariant equations describing the electromagnetic interactions between N spin-1/2 particles. In the covariant formulation each particle is described by a Dirac spinor. It i...
Scaling and universality in two dimensions: three-body bound states with short-ranged interactions

2011/10/8
Abstract: The momentum space zero-range model is used to investigate universal properties of three interacting particles confined to two dimensions. The pertinent equations are first formulated for a ...

2011/8/4
Abstract: We explore the effective long-range interaction of charged particles confined to a curved low-dimensional manifold using the example of a helical geometry. Opposite to the Coulomb interactio...

We present a scalable method for generation of a cluster state for measurement-based quantum computing using van der Waals or dipole-dipole interactions between neutral atoms or polar molecules in an ...

Time-Dependent Density Functional Theory for Driven Lattice Gas Systems with Interactions Driven Lattice Gas Systems with Interactions
Time-Dependent Density Functional Theory Driven Lattice Gas Systems
2010/11/23
We present a new method to describe the kinetics of driven lattice gases with particle-particle
interactions beyond hard-core exclusions. The method is based on the time-dependent density

Three-body exclusion principle, duality mapping, and exact ground state of a harmonically trapped, ultracold Bose gas with three-body hard-core interactions in one dimension
duality mapping exact ground state of a harmonically trapped ultracold Bose gas with three-body hard-core interactions
2010/11/19
Motivated by previous suggestions that three-body hard-core interactions in lower-dimensional
ultracold Bose gases might provide a way for creation of non-Abelian anyons, the exact ground
state of a...
