Chronological structure of a Gödel type universe with negative cosmological constant
Abstract We show that the Gödel solution of five-dimensional gauged supergravity contains either closed time-like curves through every space–time point or none at all, dependent on the rotational parameter. In addition, we present a deformation of...

Developing Superconducting Flux Qubit by Using Epitaxial NbN/AlN/NbN Junction
Abstract In an effort to eliminate the intrinsic noise sources that contained within the superconducting qubit circuits, we successfully fabricate superconducting flux qubit circuits (rf SQUID) with full epitaxially grown NbN/AlN/NbN tunnel...

Spectral Response and Noise Temperature of a 2.5 THz Spiral Antenna Coupled NbN HEB Mixer
Abstract We report on a 2.5 THz spiral antenna coupled NbN hot electron bolometer (HEB) mixers, fabricated with in-situ process. The receiver noise temperature with lowest value of 1180K is in good agreement with calculated quantum efficiency factor ...

CAST Microbulk Micromegas in the Canfranc Underground Laboratory
Abstract During the last taking data campaigns of the CAST experiment, the micromegas detectors have achieved background levels about 5 to 9 ×10−6keV−1cm−2s−1 between 2 and 9 keV. This performance has been possible thanks to the introduction of the...

The Decrease of the Critical Current of Coated Conductors When a Perpendicular Magnetic Field is Applied: A Josephson Effect Point of View
Abstract A large decrease is observed in the critical current density of YBCO coated conductors (CC) and related compounds when a strong perpendicular magnetic field is applied. While measurements are generally carried out at 77K only, here we...

Flow and geometry induced scattering of high frequency acoustic duct modes
Abstract Cut-on cut-off transition of acoustic modes in hard-walled ducts with irrotational mean flow is well understood for Helmholtz numbers of order unity. Previous finite-element simulations of this phenomenon, however, appear to indicate the...

A GPU approach to parallel replica-exchange polymer simulations
Abstract We investigate new programming techniques for parallel tempering Monte Carlo simulations of an elementary bead-spring homopolymer model using graphics processing units (GPUs). For a precise estimation of statistical quantities, like the...

Results for a critical threshold, the correction-to-scaling exponent and susceptibility amplitude ratio for 2d percolation
Abstract We summarize several decades of work in finding values for the percolation threshold pc for site percolation on the square lattice, the universal correction-to-scaling exponent, and the susceptibility amplitude ratio C+/C–, in two...

The Speed of Gravitational Waves in Brane-worlds
Abstract We discuss the speed of gravitational waves in a brane world scenario and show that if the extra dimension is space- like, the speed of the propagation of such waves is greater in the bulk than that on the brane. In this sense, the 4D...

Neutron production targets for a new Single Event Effects facility at the 70 MeV Cyclotron of LNL-INFN
Abstract A high-current (500 μA) variable energy (35-70 MeV) proton cyclotron is under construction at the INFN LNL for the SPES project and will be commissioned in 2014. This opens up the prospect of a high flux neutron irradiation facility in...

From Reversible to Irreversible Computations
Abstract In this paper we study the relation between reversible and irreversible computation applicable to different models of computation — here we are considering classical and quantum computation. We develop an equational theory of reversible...

Recombination-enhanced processes in solar cell degradation
Abstract In this paper we briefly survey processes enhanced by high carrier densities and cases relevant to solar cell systems. The criteria for distinguishing between the main types of mechanism (local excitation, local heating and the...
