Thermal processes generated in quark-gluon plasma by yoctosecond laser pulses
In this paper the thermal processes generated by yoctosecond (10-24 s) laser
pulses in QGP are investigated. Considering that the relaxation time in QGP is
of the order of 1 ys it is shown that in QGP the yoctosecond laser pulses can
generate the thermal waves with velocity v = c (0.3 fm/ys).
Key words: QGP, thermal waves, yoctosecond pulsesComment: 12pg

Collapse of unit horizontal bundles equipped with a metric of Cheeger-Gromoll type
We study unit horizontal bundles associated with Riemannian submersions.
First we investigate metric properties of an arbitrary unit horizontal bundle
equipped with a Riemannian metric of the Cheeger-Gromoll type. Next we examine
it from the Gromov-Hausdorff convergence theory point of view, and we state a
collapse theorem for unit horizontal bundles associated with a sequence of
warped Riemannian submersions.Comment: 9 page
Anthropic calculation of the velocity and acceleration of the space-time
In this paper considering quantum heat transport equation (QHT) formulated in
our earlier papers the temperature for universes with G < 0 is calculated. As
the solution of complex QHT (Schrodinger type equation), the temperature is
complex also. We argue that due to anthropic limitation of the observer
ImT(r,t)=0 From this condition the discretization of space-time radius R,
velocity of the universe expansion v, Hubble parameter H and acceleration of
the expansion a are calculated. The agreement with observational data for our
Universe is quite good. PACS 98.62.Py PACS 98.80.Bp PACS 98.80.CqComment: 7pg
Sub- and Supersonic Heat Motion Induced by Femtosecond Laser Pulses
In this paper the superheating of electron plasma by femtosecond laser pulses
is investigated. With Heaviside thermal equation (Lasers in Engineering, 12,
(2002), p.17) the generation of superhot electrons is described. It is shown
that in hot electron plasma (i.e. with electron energies >5MeV) the thermal
shock waves can be generated. Key words: Femtosecond laser pulses; Hot electron
plasma; Shock thermal waves.Comment: 11 pages, 11 figure
Nanoscience with Attosecond Laser Pulses
In this paper the interaction of attosecond laser pulses with matter is
investigated. The scattering and potential motion of heat carriers as well as
the external force are considered. Depending on the ratio of the scatterings
and potential motion the heat transport is described by the thermal forced
Klein-Gordon or thermal modified telegraph equation. For thermal Heisenberg
type relation V tau=hbar (tau is the relaxation time and V is the potential)
the heat transport is described by the thermal distortionless damped wave
equation. In this paper Klein-Gordon modified telegraph equation and wave
equation are solved. Key words: Attosecond laser pulses; Quantum heat transport
equation; Klein-Gordon thermal equation.Comment: 10 page

The Green function for thermal waves induced by attosecond laser pulses in one and three dimensions
In this paper the solution of the hyperbolic Klein-Gordon thermal equation
are obtained and discussed. The analytical form of the solution - Green

only in three dimensional case the undisturbed, with one value of the velocity,
thermal wave can be generated by attosecond laser pulses. The conductivity for
the space-time inside the atom is calculated and the value sigma_0=10^6
1/(Omega m) is obtained.
