We report the rst observation of the decay D+ ! 0e+e in two analyses with signi cances
of 5.6 (total) and 5.8 (statistical) standard deviations. These analyses also provide the rst form factor me...
Travelling-waves consistent with turbulence-driven secondary flow in a square duct
turbulence-driven secondary flow square duct
2010/11/12
We present numerically determined travelling-wave solutions for pressure-driven flow through a straight duct with a square cross-section. This family of solutions represents typical coherent structure...
We investigate the effect of induced massive radiation given off during the time of collapse of a massive spherically symmetric domain wall in the context of the functional Schr¨odinger formalism.Here...
Chiral dynamics predictions for eta' -> eta pi pi
Chiral dynamics predictions eta' -> eta pi pi
2011/1/10
The Dalitz plot distribution of the ′ → decays is analyzed in the frameworks of
large-NC Chiral Perturbation Theory and Resonance Chiral Theory. The size of the ′
branching ratios is thus sati...
In this article we give a brief review of the fundamental physics that can be done with the future space-based gravitational wave detector LISA. This includes detection of gravitational wave bursts co...
The Work Done by an External Field
Kubo-Greenwood formula DC conductivity longitudinal field transverse field
2010/11/24
From the change in kinetic energy induced by an external field, we discuss the applicable conditions for the Mott-Davis and Moseley-Lukes form of the Kubo-Greenwood formula (KGF) for the electrical co...
Inducing Barbero-Immirzi Connections along SU(2)-reductions of Bundles on Spacetime
Barbero-Immirzi Connections Bundles Spacetime
2010/12/20
We shall present here a general apt technique to induce connections along bundle reductions
which is different from the standard restriction. The technique is a generalization of the mechanism presen...
We show that a metamaterial slab with arbitrary values of epsilon and mu behaves as a cloak at a finite frequency for a small object located sufficiently close to it due to the suppression of the obje...
We present an update of our calculation of the form factor for ¯B →D∗ln¯ at zero recoil, with higher statistics and finer lattices.
A geometric solution to the coincidence problem, and the size of the landscape as the origin of hierarchy
geometric solution coincidence problem
2010/12/22
Without assuming necessary conditions for observers such as galaxies or entropy production, we show that the causal patch measure predicts the coincidence of vacuum energy and present matter density. ...
A projective Dirac operator on CP^2 within fuzzy geometry
projective Dirac operator fuzzy geometry
2010/12/22
We propose an ansatz for the commutative canonical spin_c Dirac operator on CP^2 in a global geometric approach using the right invariant (left action-) induced vector fields from SU(3). This ansatz ...
A classical particle that is initially in a classically allowed region of a potential is not confined to this region for all time if its energy is complex. Rather, the particle may travel through com...
The tripartite entanglement is examined when one of the three parties moves with a uniform acceleration with respect to other parties. As Unruh effect indicates, the tripartite entanglement exhibits ...
Thermally induced 0-pi phase transition in Josephson junctions through a ferromagnetic oxide film
Thermally induced 0-pi phase transition Josephson junctions through ferromagnetic oxide film
2010/11/9
We investigate the Josephson transport through a ferromagnetic oxide film, e.g., La$_2$BaCuO$_5$, theoretically. Using the recursive Green's function technique, we found the formation of a pi-junction...
Dynamical Casimir-Polder force on a partially dressed atom near a conducting wall
Dynamical Casimir-Polder force partially dressed atom conducting wall
2010/11/9
We study the time evolution of the Casimir-Polder force acting on a neutral atom in front of a perfectly conducting plate, when the system starts its unitary evolution from a partially dressed state. ...
