Spin-gapped wave function as normal state in attractive Hubbard model
Abstract With the pseudogap in cuprate superconductors in mind, we study an attractive Hubbard model on the square lattice, in which the mechanism of superconductivity undergoes a crossover at |Uco|/t from a BCS type to a Bose-Einstein condensation...

Study on reduction of gamma-ray noise for a pixel-type position-sensitive Li-glass neutron detector
Abstract A pixel-type position-sensitive Li-glass neutron detector has been developed in the Hokkaido University and applied to neutron transmission measurements for obtaining wavelength-dependent neutron images due to its high counting rate. This...

Conserved quantities and the algebra of braid excitations in quantum gravity
Abstract We derive conservation laws from interactions of braid-like excitations of embedded framed spin networks in quantum gravity. We also demonstrate that the set of stable braid-like excitations form a noncommutative algebra under braid...

Exotic hairy black holes
Abstract We study black hole solutions in asymptotically AdS 4 spacetime with scalar hair. Following AdS/CFT dictionary...

CFT duals for attractor horizons
Abstract In this paper we generalize the results of Guica et al. (2008) [M. Guica, T. Hartman, W. Song, A. Strominger, arXiv:0809.4266 [hep-th]] to 5-dimensional Anti-de Sitter gravity theories with neutral scalars non-minimally coupled to gauge...

The Assessment of Overvoltage Protection Within Energization of Offshore Wind Farms
Abstract The beneficiary of Offshore Wind Farms (OWF) to land wind farms in the sense of more power productivity and land view disturbance leads to more investment and consideration. Nevertheless, the maintenance of OWFs is a significant issue due...

The optical absorption of the neutral vacancy in diamond
Abstract Optical absorption by the neutral vacancy in diamond has been predicted to occur between the ground 1 E state and the 1 T 2 excited state. Both these states are orbitally...

Doubly heavy baryons with chiral partner structure
Abstract The spectrum and dominant strong decay properties of the doubly heavy baryons are revisited by using a chiral effective model with the chiral partner structure. By regarding the doubly heavy baryons in the ground states and light angular...

A micro-reactor array for fluorescence markers-based bioaffinity assays
Abstract This work reports the design, fabrication and optical characterization of a micro-reactor array (MRA), consisting of a matrix of transparent wells realized on a opaque silicon substrate, coupled with a CMOS Single-Photon Avalanche Diode...

Fragmentation, factorization and infrared poles in heavy quarkonium production
Abstract We explore the role of soft gluon exchange in heavy quarkonium production at large transverse momentum. We find uncanceled infrared poles at NNLO that are not matched by conventional NRQCD matrix elements. We show, however, that gauge...

QCD corrections to radiative B decays in the MSSM with minimal flavor violation
Abstract We compute the complete supersymmetric QCD corrections to the Wilson coefficients of the magnetic and chromomagnetic operators, relevant in the calculation of b → s ...

Fine structure constant in the spacetime of a cosmic string
Abstract We calculate the fine structure constant in the spacetime of a cosmic string. In the presence of a cosmic string the value of the fine structure constant reduces. We also discuss on numerical results.

Solar neutrinos as probes of neutrino–matter interactions
Abstract Data from solar neutrino and KamLAND experiments have led to a discovery of nonzero neutrino masses. Here we investigate what these data can tell us about neutrino interactions with matter, including the poorly constrained flavor-changing ν ...

Gravitoelectromagnetic inflation from a 5D vacuum state: A new formalism
Abstract We propose a novel formalism for inflation from a 5D vacuum state which could explain both, seeds of matter and magnetic fields in the early universe.

A zero-mode quantization of the skyrmion
Abstract In the semi-classical approach to the Skyrme model, nuclei are approximated by quantum mechanical states on a finite-dimensional space of field configurations; in zero-mode quantization this space is generated by rotations and isorotations. ...
