Diego Meschini, Markku Lehto
This article deals with empty spacetime and the question of its physical reality. By "empty spacetime" we mean a collection of bare spacetime points, the remains of ridding spaceti…
Driving the slow-light soliton by controlling laser field
A. V. Rybin, I. P. Vadeiko, A. R. Bishop
In the framework of the nonlinear -model we investigate propagation of a slow-light soliton in atomic vapors and Bose-Einstein condensates. The velocity of the slow-light solito…
Phase transitions on Markovian bipartite graphs - an application of the zero-range process
Otto Pulkkinen, Juha Merikoski
We analyze the existence and the size of the giant component in the stationary state of a Markovian model for bipartite multigraphs, in which the movement of the edge ends on one s…
Geometry, pregeometry and beyond
Diego Meschini, Markku Lehto, Johanna Piilonen
This article explores the overall geometric manner in which human beings make sense of the world around them by means of their physical theories; in particular, in what are nowaday…
