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 functions are calculated for one and three dimensional cases. It is shown that 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.   Key words: Attosecond laser pulses; Klein-Gordon equation; Green functions.
