A new closed formula for the Hermite interpolating polynomial with applications on the spectral decomposition of a matrix
Aristides I. Kechriniotis, Konstantinos K. Delibasis, Christos Tsonos +1
We present a new closed form for the interpolating polynomial of the general univariate Hermite interpolation that requires only calculation of polynomial derivatives, instead of d…
AC and DC conductivity correlation: The coefficient of Barton--Nakajima--Namikawa relation
Christos Tsonos, Athanasios Kanapitsas, Aristides Kechriniotis +1
It has been some time since an empirical relation, which correlates DC with AC conductivity and contains a loosely defined coefficient thought to be of order one, was introduced by…
The linear sigma model at a finite isospin chemical potential
Hong Mao, Nicholas Petropoulos, Song Shu +1
The effect of finite isospin chemical potential to the effective masses of the mesons at finite temperature is investigated in the framework of the O(4) linear sigma model with exp…
A study of the pion effective mass at finite temperature using the linear sigma model
Nicholas Petropoulos
We have used the Cornwall--Jackiw--Tomboulis method of composite operators and its formulation at finite temperature by Amelino-Camelia and Pi, in order to calculate the effective…
Linear sigma model at finite temperature
Nicholas Petropoulos
The chiral phase transition is investigated within the framework of thermal field theory using the O(N) linear sigma model as an effective theory. We calculate the thermal effectiv…
Baryogenesis at the electroweak phase transition
Nicholas Petropoulos
A possible solution to the observed baryon asymmetry in the universe is described, based on the physics of the standard model of electroweak interactions. At temperatures high enou…
