Controllability of degenerate and singular parabolic problems: the double strong case with Neumann boundary conditions [PDF]
Opuscula Mathematica, 2019 We prove a null controllability result for a parabolic problem with Neumann boundary conditions. We consider non smooth coefficients in presence of a strongly singular potential and a strongly degenerate coefficient, both vanishing at an interior point ...

O(N) universality and the chiral phase transition in QCD
, 2010 We discuss universal scaling properties of (2+1)-flavor QCD in the vicinity of the chiral phase transition at vanishing as well as non-vanishing light quark chemical potential (mu_l). We provide evidence for O(N) scaling of the chiral order parameter in (

Vanishing gaps in photonic crystals and other periodic potentials [PDF]
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016 Using Floquet-Bloch theory, we find incipient bands (vanishing gaps) in the band structures of one-dimensional photonic crystals with a piece-wise constant profile of the refractive index, and in the band structures of continuously differentiable periodic potentials. The emphasis is on potentials that allow solutions in an exact analytical form.

Existence of Sign-Changing Solutions for a Class of p(x)-Biharmonic Kirchhoff-Type Equations
AxiomsThis paper mainly studies the existence of sign-changing solutions for the following px-biharmonic Kirchhoff-type equations: −a+b∫RN1p(x)|Δu|p(x)dxΔp(x)2u+V(x)|u|p(x)−2u = Kxf(u),x∈RN, where Δp(x)2u=Δ|Δu|p(x)−2Δu is the p(x) biharmonic operator, a,b>0 ...

On consistency of hydrodynamic approximation for chiral media
Physics Letters B, 2016 We consider chiral liquids, that is liquids consisting of massless fermions and right–left asymmetric. In such media, one expects existence of electromagnetic current flowing along an external magnetic field, associated with the chiral anomaly.

Lattice QCD at non-vanishing density: phase diagram, equation of state
, 2003 We propose a method to study lattice QCD at non-vanishing temperature (T) and chemical potential (\mu). We use n_f=2+1 dynamical staggered quarks with semi-realistic masses on L_t=4 lattices.

Bound states of nonlinear Schrödinger equations with potentials vanishing at infinity
Journal d'Analyse Mathématique, 2005 We deal with a class on nonlinear Schrödinger equations (NLS) with potentials V(x)\sim |x|^{-\alpha} , 0<\alpha<2 , and K(x)\sim |x|^{-\beta ...

Advanced Engineering Materials, EarlyView.A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Tachyon cosmology with non-vanishing minimum potential: a unified model
, 2012 We investigate the tachyon condensation process in the effective theory with non-vanishing minimum potential and its implications to cosmology. It is shown that the tachyon condensation on an unstable three-brane described by this modified tachyon field ...
