Abstract Isospin effects on the optical potentials of kaons and antikaons in dense hadronic matter are investigated using a chiral SU(3) model. These effects are important for asymmetric heavy ion collision experiments. In the present work the dispersion relations are derived for kaons and antikaons, compatible with the low energy scattering data, within our model approach. The relations result...

A new technique to investigate small chemical potential effects on hadron quantities using lattice QCD simulations is developed. A Taylor series expansion of hadron screening mass in µ/T is used. It is successfully applied to study the properties of nucleon, pseudo-scalar and vector meson screening masses around the deconfinement phase transition at finite baryonic density by evaluating the Tay...

We investigate the ground states of the Abelian Higgs model in AdS4 with various choices of parameters, and with no deformations in the ultraviolet other than a chemical potential for the electric charge under the Abelian gauge field. For W-shaped potentials with symmetrybreaking minima, an analysis of infrared asymptotics suggests that the ground state has emergent conformal symmetry in the in...

A class of asymptotically free scalar theories with O(N) symmetry, defined via the eigenpotentials of the Gaussian fixed point (Halpern-Huang directions), are investigated using renormalization group flow equations. Explicit solutions for the form of the potential in the nonperturbative infrared domain are found in the large-N limit. In this limit, potentials without symmetry breaking essential...

A dissipation theory is proposed for the potentials-based FDTD algorithm case of inhomogeneous lossless media. We show that under Courant-Friedrichs-Lewy (CFL) limit, equations describing time evolution scalar and vector potentials can be seen as a system. The developed provides insights into how electromagnetic energy power flow are approximated in schemes. It also used to create new algorithm...

For the theory of a single scalar field φ with a quartic potential V (φ), we find semianalytic expressions for the Euclidean action in both four and three dimensions. The action in four dimensions determines the quantum tunneling rate at zero temperature from a false vacuum state to the true vacuum state; similarly, the action in three dimensions determines the thermal tunneling rate for a fini...

Inflation, a cornerstone of the modern framework for understanding the early universe @1,2#, predicts the initial conditions for the formation of structure and the cosmic microwave background ~CMB! anisotropies. During inflation, the primordial scalar ~density! and tensor ~gravitational wave! perturbations generated by quantum fluctuations are redshifted beyond the Hubble radius, becoming froze...

The potential concept that is successful in classical electrodynamics should also be applicable to the nonlinear electromagnetic forces acting on matter. The obvious method of determining these potentials should be provided by Helmholtz’s theorem. It is found, however, that the theorem fails in most practical instances. Other methods to find the potentials – as pursued in plasma physics – are e...

We demonstrate reverse-time imaging using multicomponent elastic wavefields. The elastic data are used as boundary conditions for a numeric solution to the elastic wave-equation solved using a staggeredgrid finite-difference implementation. P and S components are not separated from recorded data, but are extrapolated together as part of a vector wavefield. A straightforward extension to the cro...

where t ∈ [0, T ] for some T > 0, x ∈ T (the one-dimensional torus), and subscripts denote partial derivatives. Equation (1.1) does not admit in general classical solutions for the associated Cauchy problem, even if the initial datum is smooth. On the other hand, if f is non-linear, there exist in general infinitely many weak solutions. An admissibility condition, the so-called entropic conditi...
