Tuning of Anisotropy by Controlling Excess Fe Concentration in FeyTe0.6Se0.4
Abstract We have grown single crystals of FeTe0.6Se0.4 and Fe0.95Te0.6Se0.4 by a conventional self-flux method. The superconducting properties were investigated by magnetization measurements. We found that the anisotropy of the superconducting state ...

Note on scalars, perfect fluids, constrained field theories, and all that
Abstract The relation of a scalar field with a perfect fluid has generated some debate along the last few years. In this Letter we argue that shift-invariant scalar fields can describe accurately the potential flow of an isentropic perfect fluid,...

Constraining the Natural MSSM through tunneling to color-breaking vacua at zero and non-zero temperature
Abstract We re-evaluate the constraints on the parameter space of the minimal supersymmetric standard model from tunneling to charge- and/or color-breaking minima, taking into account thermal corrections. We pay particular attention to the region...

Lattice QCD-based equations of state at vanishing net-baryon density
Abstract We present realistic equations of state for QCD matter at vanishing net-baryon density which embed recent lattice QCD results at high temperatures combined with a hadron resonance gas model in the low-temperature, confined phase. In the...

Confirming Inextensional Theory
Abstract Thin, initially-flat plates can deform inextensionally and elastically during large out-of-plane deformations. This paper revisits an analytical method for describing the developable shapes of displaced plate, in order to quantify and...

Bouncing braneworlds
Abstract We study cosmological braneworld models with a single timelike extra dimension. Such models admit the intriguing possibility that a contracting braneworld experiences a natural bounce without ever reaching a singular state. This feature...

Correlation functions of XX0 Heisenberg chain, q-binomial determinants, and random walks
Abstract The XX0 Heisenberg model on a cyclic chain is considered. The representation of the Bethe wave functions via the Schur functions allows to apply the well-developed theory of the symmetric functions to the calculation of the thermal...

New fast least-squares algorithm for estimating the best-fitting parameters due to simple geometric-structures from gravity anomalies
Abstract A new fast least-squares method is developed to estimate the shape factor (q-parameter) of a buried structure using normalized residual anomalies obtained from gravity data. The problem of shape factor estimation is transformed into a...

New symmetries for Abelian gauge theory in superfield formulation
Abstract We show the existence of some new local, covariant and continuous symmetries for the BRST invariant Lagrangian density of a free two(1+1)-dimensional (2D) Abelian U(1) gauge theory in the framework of superfield formalism. The Noether...

Supersymmetric index of the M-theory 5-brane and little string theory
Abstract We propose a six-dimensional framework to calculate the supersymmetric index of M-theory 5-branes wrapped on a six-manifold with product topology M 4×T 2, where M 4 is a...

Role of photoproduction in exotic meson searches
Abstract We discuss two production mechanisms of the J PC=1−+ exotic meson, hadroproduction, using pion beams and photoproduction. We show that the ratio of exotic to nonexotic, in particular the a 2,...

Conservation of particle multiplicities between chemical and thermal freeze-out
Abstract The evolution of a hadronic system after its chemical decomposition is described through a model that conserves the hadronic multiplicities to their values at chemical freeze-out. In the partition function describing the model all known...

Meson–baryon scattering in QCD2 for any coupling
Abstract Extending earlier work on strong-coupling meson–baryon scattering in QCD2, we derive the effective meson–baryon action for any value of the coupling constant, in the large-N c ...

Gauged Lμ−Lτ with large muon anomalous magnetic moment and the bimaximal mixing of neutrinos
Abstract We consider the gauging of L μ −L τ as an explanation of a possibly large muon anomalous magnetic moment. ...
