Systematic Direct Approach for Optimizing Continuous-thrust Earth-orbit Transfers
Abstract This article presents a systematic direct approach to carry out effective optimization of a wide range of continuous-thrust Earth-orbit transfers with intermediate-level thrust acceleration, including minimum-time (with a single burn arc)...

GLRT Detectors for Aircraft Wake Vortices in Clear Air
Abstract In this article, radar echoes of aircraft wake vortices are modeled as weighted sums of the frequency components of the echoes with a special covariance matrix for the weighted coefficients. With a proposed detection scheme, two...

Black hole relics in large extra dimensions
Abstract Recent calculations applying statistical mechanics indicate that in a setting with compactified large extra dimensions a black hole might evolve into a (quasi-)stable state with mass close to the new fundamental scale M ...

Remarks on fundamental string cosmology
Abstract In recent work, it was shown that velocity-dependent forces between moving strings or branes lead to an accelerating expanding universe without assuming the existence of a cosmological constant. Here we show that the repulsive...

WIMP dark matter direct-detection searches in noble gases
Abstract Cosmological observations and the dynamics of the Milky Way provide ample evidence for an invisible and dominant mass component. This so-called dark matter could be made of new, colour and charge neutral particles, which were...

Network formation by contact arrested propagation
Abstract We propose here a network growth model which we term Contact Arrested Propagation (CAP). One representation of the CAP model comprises a set of two-dimensional line segments on a lattice, propagating independently at constant speed in both...

Singularity-free gravitational collapse and asymptotic safety
Abstract A general class of quantum improved stellar models with interiors composed of non-interacting (dust) particles is obtained and analyzed in a framework compatible with asymptotic safety. First, the effective exterior, based on the Quantum...

Polyakov loop potential at finite density
Abstract The Polyakov loop potential serves to distinguish between the confined hadronic and the deconfined quark–gluon plasma phases of QCD. For N ...

Discovery of large scale tensor mode and chaotic inflation in supergravity
Abstract The BICEP2 collaboration has recently reported a large tensor fluctuation in the cosmic microwave background, which suggests chaotic inflation models. In this letter, we reconsider the chaotic inflation model in the supergravity. We...

Quantum mechanics of null polygonal Wilson loops
Abstract Scattering amplitudes in maximally supersymmetric gauge theory are dual to super-Wilson loops on null polygonal contours. The operator product expansion for the latter revealed that their dynamics is governed by the evolution of...

Cosmological constraint on the Zee model
Abstract It is well known that the Zee model induces small neutrino masses by radiative corrections, where the bi-maximal flavor mixing is possible. We analyze the cosmological condition in order for the baryon asymmetry generated in the early...

Understanding the penguin amplitude in B→φK decays
Abstract We calculate branching ratios for pure penguin decay modes, B→φK decays using perturbative QCD approach. Our results of branching ratios are consistent with the experimental data and larger than those obtained from the naive factorization...

Weakly first order cosmological phase transitions and fermion production
Abstract We study weakly first order cosmological phase transitions in finite temperature field theories. Focusing on the standard electroweak theory and its minimal supersymmetric extension, we identify the regimes of Higgs masses for which the...
