The rocket equations for decays of elementary particles

The decay of elementary particles is described nonrelativistically and using the method of the special theory of relativity. Then the Tsiolkovskii rocket equation is applied to the one photon decay of the excited nucleus of the Mössbauer effect. The formation time of photons during decay is supposed nonzero. The Meščerskii equation is possible to identify with the bremsstrahlung equation. All decays described in the ``Review of Particle physics properties'' can be investigated from the viewpoint of the rocket equations

Radiation of the blackbody in the external field

The blackbody is considered in the external general field. The additional coefficients of stimulated emission and absorption are introduced into the Einstein mechanism. Then, the generalized Planck formula is derived. The Einstein and Debye formula for the specific heat is possible to generalize. The application of the theory to the sonoluminescence, the relic radiation and solar spectrum is discussed.

From the Foucault pendulum to the galactical gyroscope and LHC

We consider the Foucault pendulum, isosceles triangle pendulum and the general triangle pendulum rotating on the Earth. As an analogue, planet orbiting in the rotating galaxy is considered as the giant galactical gyroscope. The Lorentz and the Bargman-Michel-Telegdi equations are generalized for the rotating system. These equations are inevitable for LHC where orbital photons "feels" the Coriolis force caused by the rotation ofthe Earth.

Quantum mechanical corrections to the Alfven waves

The hydrodynamical model of quantum mechanics based on the Schroedinger equation is combined with the magnetohydrodynamical term to form so called quantum magnetohydrodynamic equation. It is shown that the quantum correction to the Alfven waves follows from this new equation. The possible generalization is considered for the so called nonlinear Schroedinger equation and for the situation where dissipation is described by the Navier-Stokes equation.

Creativity leading to discoveries in particle physics and relativity

The basic ingredients of the discovery creativity is presented. Understanding, problem solving, heuristics, computer thinking, technology and physics, and so on. We present some discoveries from the viewpoint of creativity. The Dirac equation, the Riccati equation, the nonlinear Schroedinger equation, the quantum navier Sokes equation, the equation of the quantum magnetohydrodynamics and so on. We discuss nonlinear Lorentz transformation involving the maximal acceleration which we relate to the Hagedorn temperature, and possible dependence of mass on acceleration. We consider the relation between physics and technology and so on.

Volkov solution for two laser beams and ITER

We find the solution of the Dirac equation for two plane waves (laser beams) and we determine the modified Compton formula for the scattering of two photons on an alectron. The practical meaning of the two laser beams is, that two laser beams impinging on a targed which is constituted from material in the form of a foam, can replace 100-200 laser beams impinging on a normal targed. It means that the nuclear fusion with two laser beams is realistic in combination with the nuclear reactor such as ITER.

The propagation of a pulse in the real string and rods

The elastic string (rod) of a large mass M is considered, the left end of which is fixed to a body of a small mass m. The second body of mass m is fixed to the right end of the string. The force of the delta-function form is applied to the left side of the string. We find the propagation of a pulse in the system. The problem is related to the quark-string model of mesons.

Radiation of the Gravitational and Electromagnetic Binary Pulsars

The energy-loss formula of the production of gravitons by the binary is derived in the source theory formulation of gravity. Then, the quantum energy-loss formula involving radiative corrections is derived. We postulate an idea that gravitational pulsars are present in our universe and that radiative corrections play a role in the physics of the cosmological scale. In the last part of the article, we consider so called electromagnetic pulsar which is formed by two particles with the opposite electrical charges moving in the constant magnetic field and generating the electromagnetic pulses. We think that the cosmological analogue is possible.

Volkov solution for an electron in the two wave fields

It is considered the Dirac equation with two different four-potentials of the plane electromagnetic waves. We derive the equation for the wave function which is generalized form of the Volkov equation. We find the solutions of the Dirac equation for two orthogonal waves. We determine the modified Compton formula for the scattering of two photons on an electron.

Compton effect in dielectric medium

We determine the Compton effect from the Volkov solution of the Dirac equation for a process in a medium with the index of refraction n. Volkov solution involves the mass shift, or, the mass renormalization of an electron mass. We determine the modified Compton formula for the considered physical situation. The index of refraction causes that the wave lenghths of the scattered photons are shorter for some angles than the wave lengths of the original photons. This is anomalous Compton effect. Since the wave length shift for the visible light is only 0,01 percent, it means that the Compton effect for the visible light in the dielectric medium needs experimental virtuosity.

Light in metric space-time and its deflection by the screw dislocation

We derive the light deflection caused by the screw dislocation in space-time. Space-time is medium which can be deformed in such a way that its deformation is equivalent to the existence of metric which is equivalent to gravity. The existence of the screw dislocations in cosmology is hypothetically confirmed by observation of light bursts which can be interpreted as the annihilation of the giant screw dislocations with antidislocations. The origin of the gravitational bursts are analogical as the optical ones. They can be probably detected by LIGO, VIRGO, GEO, TAMA and so on. The dislocation theory of elementary particles is discussed.

Massive photons in particle and laser physics

The massive electrodynamics is applied to the Dirac equation to find the generalized Volkov solution with massive photon field. The resulting equation is the Riccati equation which cannot be solved in general. We use the approximative Volkov function for massive photons and then consider an electron in the periodic field and in the laser pulse of the delta-function form. We derive the modified Compton formulas for the interaction of the multiphoton object with an electron for both cases.

Theory of the magnetronic laser

We determine the total power of radiation of electron moving in the planar magnetron fields and the power spectrum generated by a single electron and by a system of N electrons moving coherently in the planar magnetron. We argue that for large N and high intensity of electric and magnetic fields, the power of radiation of such magnetronic laser, MAL, can be sufficient for application in the physical, chemical, biological and medicine sciences. In medicine, the magnetronic laser, can be used for the therapy of the localized cancer tumors. The application of MAL in CERN as an ion source for LHC is not excluded.

The Space-time Transformations Between Accelerated Systems

We determine transformations between coordinate systems which are mutually in linear accelerated motion. In case of the symmetrical linear mutual acceleration, we immediately get the maximal acceleration limit which was derived by Caianiello from quantum mechanics. The derived results can play crucial role in modern particle physics.

Electron in the Ultrashort Laser Pulse

After the clasical approach to acceleration of a charged particle by delta-form impulsive force, we consider the corresponding quantum theory based on the Volkov solution of the Dirac equation. We determine the modified Compton formula for frequency of photons generated by the scattering of the delta-form laser pulse on the electron in a rest.

To the nonlinear quantum mechanics

The Schroedinger equation with the nonlinear term is derived by the natural generalization of the hydrodynamical model of quantum mechanics. The nonlinear term appears to be logically necessary because it enables explanation of the classical limit of the wave function, the collaps of the wave function and solves the Schroedinger cat paradox.

The circle electromagnetic pulsar

The power spectrum formula of the synchrotron radiation generated by the electron and positron moving along the concentric circles at the opposite angular velocities in homogenous magnetic field is derived in the Schwinger version of quantum electrodynamics. The asymptotical form of this formula is found. The spectrum depends periodically on time which means that the system composed from electron, positron and magnetic field forms the pulsating system. The similar calculations are performed in the case that the circles of motion are excentric.

The Cherenkov-Compton effect in particle physics

The two-photon production by motion of a charged particle in a medium is considered. This process is called Cherenkov-Compton effect because the production of photons is calculated from the Feynman diagram for the Compton effect in a medium. This process is not forbidden in quantum electrodynamics of dielectric media. The cross section of his process in Mandelstam variables is calculated for pair of photons with one moving at the opposite direction to the electron motion and the second one inside Cherenkov cone. The opposite motion is not caused by the collision with a particle of a medium . The relation of this process to the CERN experiments is considered.
