New methods in the theory of quantum spin systems

- V. Ulyanov, O. Zaslavskii
- Physics
- 1 July 1992

Abstract Recently developed methods to investigate quantum spin systems are reviewed. These methods are based on somewhat unconventional applications of the spin coherent state technique developed in… Expand

Regular black holes and energy conditions

- O. Zaslavskii
- Physics
- 14 April 2010

Abstract We establish the relationship between the space–time structure of regular spherically-symmetrical black holes and the character of violation of the strong energy condition (SEC). It is shown… Expand

Geometry of nonextreme black holes near the extreme state

- O. Zaslavskii
- Physics
- 15 August 1997

A nonextreme black hole in a cavity can achieve the extreme state with a zero surface gravity at a finite temperature on a boundary, the proper distance between the boundary and the horizon being… Expand

Acceleration of particles by nonrotating charged black holes?

- O. Zaslavskii
- Physics
- 27 July 2010

Recently, in the series of works a new effect of acceleration of particles by black holes has been found. Under certain conditions, the energy in the center-of-mass system can become infinitely… Expand

Acceleration of particles as a universal property of rotating black holes

- O. Zaslavskii
- Physics
- 21 July 2010

We argue that the possibility of having infinite energy in the center-of-mass frame of colliding particles is a generic property of rotating black holes. We suggest a general model-independent… Expand

Traversable wormholes: Minimum violation of the null energy condition revisited

- O. Zaslavskii
- Physics
- 10 July 2007

It was argued in literature that traversable wormholes can exist with an arbitrarily small violation of null energy conditions. I show that if the amount of exotic material near the wormhole throat… Expand

Spin tunneling and the effective potential method

- O. Zaslavskii
- Physics
- 30 April 1990

Abstract Spin tunneling is described based on the exact correspondence between the spin system and a particle moving in a potential field. In the general case of two-axis anisotropy the potential is… Expand

Exactly solvable model of a wormhole supported by phantom energy

- O. Zaslavskii
- Physics
- 12 September 2005

We have found a simple exact solution of spherically symmetrical Einstein equations describing a wormhole for an inhomogeneous distribution of the phantom energy. The equation of state is linear but… Expand

QUASIBLACK HOLES: PROPERTIES AND CARTER-PENROSE DIAGRAMS

- S. Lemos, R. Pais, O. Zaslavskii, V. Karazin
- Physics
- 1 March 2015

Curvature tensors on distorted Killing horizons and their algebraic classification

- V. Pravda, O. Zaslavskii
- Physics, Mathematics
- 20 October 2005

We consider generic static spacetimes with Killing horizons and study properties of curvature tensors in the horizon limit. It is determined that the Weyl, Ricci, Riemann and Einstein tensors are… Expand
