Suppose that a system is known to be in one of two quantum states, $|\psi_1 > $ or $|\psi_2 >$. If these states are not orthogonal, then in conventional quantum mechanics it is impossible with one mea...
Plane-symmetric spacetimes with positive cosmological constant. The case of stiff fluids
Plane-symmetric spacetimes positive cosmological constant stiff fluids
2010/12/20
We consider plane-symmetric spacetimes satisfying Einstein’s field equations with positive cosmological constant, when the matter is a fluid whose pressure is equal to its mass-energy density (i.e. a ...
Some peculiarities of motion of neutral and charged test particles in the field of a spherically symmetric charged object in General Relativity
Motions classification Mass potential Stability conditions

We propose the method of investigation of radial motions for charged and neutral test particles in the Reissner-Nordstr¨om field by means of mass potential. In this context we analyze special features...
Kinematic Self-Similar Solutions of Locally Rotationally Symmetric Spacetimes
Locally rotationally symmetric Self-similarity

This paper contains locally rotationally symmetric kinematic self-similar perfect fluid and dust solutions. We consider three families of metrics which admit kinematic self-similar vectors of the firs...

Projective Geometry $\cal PT$-Symmetric Dirac Hamiltonian
2010/4/13
The $(3 + 1)$-dimensional (generalized) Dirac equation is shown to have the same form as the equation expressing the condition that a given point lies on a given line in 3-dimensional projective space...
