Time delay in photoemission by attosecond laser pulses

Recently the time delay in the attosecond photoemission was observed (Science,2010). In this paper we propose the description of that time delay in the framework of hyperbolic heat transport equation. We argue that the observed time delay 20 as is of the order of the thermal relaxation time for hyperbolic quantum heat transport. As the generalization of the standard quantum mechanics we propose new local Schroedinger equation with c=finite

Development of the Schrodinger equation for attosecond laser pulse interaction with Planck gas

The creation of the new particles by the interaction of the ultrarelativistic ions,from Large Hadron Collider(LHC), and attosecond laser pulse open new possibilities for laser physicists community .In this paper we propose the hyperbolic Schrödinger equation (HSE) for gas of the "classical" particles "i.e. particles with mass= Planck mass We discuss the inclusion of the gravity to the HSE The solution of the HSE for a particle in a box is obtained. It is shown that for particles with m greater than Mp the energy spectrum is independent of the mass of particle.

Attoheat transport phenomena

Fascinating developments in optical pulse engineering over the last 20 years lead to the generation of laser pulses as short as few femtosecond, providing a unique tool for high resolution time domain spectroscopy. However, a number of the processes in nature evolve with characteristic times of the order of 1 fs or even shorter. Time domain studies of such processes require at first place sub-fs resolution, offered by pulse depicting attosecond localization. The generation, characterization and proof of principle applications of such pulses is the target of the attoscience. In the paper the thermal processes on the attosecond scale are described. The Klein-Gordon and Proca equations are developed. The relativistic effects in the heat transport on nanoscale are discussed. It is shown that the standard Fourier equation can not be valid for the transport phenomena induced by attosecond laser pulses. The heat transport in nanoparticles and nanotubules is investigated.

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.Cq

Universal relaxation times for electron and nucleon gases

In this paper we calculate the universal relaxation times for electron and nucleon fermionic gases. We argue that the universal relaxation time tau(i) is equal tau(i)=h/m square v(i) where v(i)=alpha(i)c and alpha(1)=0.15 for nucleon gas and alpha(2)=1/137 for electron gas, c=light velocity. With the universal relaxation time we formulate the thermal Proca equation for fermionic gases. Key words: universal relaxation time, thermal universal Proca equation.

The modified Klein Gordon equation for neolithic population migration

In this paper the model for the neolithic migration in Europe is developed. The new migration equation, the modified Klein Gordon equation is formulated and solved. It is shown that the migration process can be described as the hyperbolic diffusion with constant speed. In comparison to the existing models based on the generalization of the Fisher approach the present model describes the migration as the transport process with memory and offers the possibility to recover the initial state of migration which is the wave motion with finite velocity.

Special relativity description of the heat propagation in Minkowski spacetime

In this paper we investigate the heat transport induced by continuous laser beams up to an intensity of about 1029 Watt/cm2. We maintain that up to this intensity nonlinear effects are negligible and that the application of the linear hyperbolic heat transport equation is fully justifiable. We show that the Fourier diffusion equation gives the speed of diffusion, v > c and breaks the causality of the thermal processes in Minkowski space-time. For hyperbolic heat transport v<c and causality is valid Key words: high energy continuous laser beams, causality, Minkowski space-time.
