Particle creation in a toroidal universe
Although current astrophysical observations provide precise information on the geometry of the universe [1], its topology remains a mystery. We don’t even know whether the universe is compact or infinite. Nevertheless, lower bounds can be placed on its size for each compact topology (see Ref. [2] and references therein). Amongst the possible topologies for the universe, those with some or all s...
متن کاملEvolution of Information and Complexity in an Ever-Expanding Universe
Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.

متن کاملParticle creation in an oscillating spherical cavity
We study the creation of massless scalar particles from the quantum vacuum due to the dynamical Casimir effect by spherical shell with oscillating radius. In the case of a small amplitude of the oscillation, to solve the infinite set of coupled differential equations for the instantaneous basis expansion coefficients we use the method based on the time-dependent perturbation theory of the quant...
متن کاملCreation-annihilation processes in the ensemble of constant particle number.
We study, in the ensemble of constant particle number, processes in which a cluster of particles is annihilated and particles are created catalytically in active sites. In this ensemble, particles belonging to a cluster of l particles jump to l distinct active sites. As examples of our prescription, we analyze numerically three nonequilibrium systems that annihilate cluster of particles that ar...
