Coherent acoustic phonons emission in copper driven by super-diffusive hot electrons
M. Lejman, V. Shalagatsky, A. Kovalenko +3
Ultrafast laser excited hot electrons can transport energy supersonically far from the region where they are initially produced. We show that this ultrafast energy transport is res…
Peculiarities in the Spectrum of the Adjoint Scalar Kinetic Operator in Yang-Mills Theory
J. Greensite, A. V. Kovalenko, S. Olejnik +3
We study the spectrum of low-lying eigenmodes of the kinetic operator for scalar particles, in the color adjoint representation of Yang-Mills theory. The kinetic operator is the co…
On topological properties of vacuum defects in lattice Yang-Mills theories
A. V. Kovalenko, S. M. Morozov, M. I. Polikarpov +1
We study correlations between low-lying modes of the overlap Dirac operator and vacuum defects, center vortices and three-dimensional volumes, in lattice SU(2) gluodynamics. The lo…
Properties of P-vortex and monopole clusters in lattice SU(2) gauge theory
A. V. Kovalenko, M. I. Polikarpov, S. N. Syritsyn +1
We study the action and geometry of P-vortices, discriminating between the percolating and finite clusters. We also discuss the interrelation of the monopoles and P-vortices. To de…
and systems in terms of P-vortices
V. G. Bornyakov, A. V. Kovalenko, M. I. Polikarpov +1
We study the action and the energy densities of the confining string in the indirect Z(2) projection of SU(2) lattice gauge theory. We find that the width of the confining string i…
Self-tuning of the P-vortices
F. V. Gubarev, A. V. Kovalenko, M. I. Polikarpov +2
We observe that on the currently available lattices the non-Abelian action associated with the P-vortices is ultraviolet divergent. On the other hand, the total area of the vortice…
