Exciton matter sustained by colossal dispersive interactions due to enhanced polarizability: Possible clue to ball lightning
Mladen Georgiev, Jai Singh
Recently Gilman has pointed out that the material state of a ball lightning is both highly cohesive and flexible. He makes a specific proposal for a cohesive state arising from (co…
Two-electron F' centers in alkali halides: A negative-U analysis
Mladen Georgiev
The existence of bound excited states of two-electron centers loosely trapped in an anion vacancy, the F' centers, is a long-standing problem of color center physics. Optical absor…
The totally asymmetric exclusion process on a ring: Exact relaxation dynamics and associated model of clustering transition
J. G. Brankov, Vl. V. Papoyan, V. S. Poghosyan +1
The totally asymmetric simple exclusion process in discrete time is considered on finite rings with fixed number of particles. A translation-invariant version of the backward-order…
Membrane solutions in M-theory
P. Bozhilov
Motivated by the recent achievements in the framework of the semiclassical limit of the M-theory/field theory correspondence, we propose an approach for obtaining exact membrane so…
On correlations and fractal characteristics of time series
Nikolay K. Vitanov, kenschi Sakai, Elka D. Yankulova
Correlation analysis is convenient and frequently used tool for investigation of time series from complex systems. Recently new methods such as the multifractal detrended fluctuati…
Integrability-Nonintegrability Structures and Individual Photons' Description as Finite Field Objects
Stoil Donev, Maria Tashkova
This paper presents an attempt to come to a natural field model of individual photons considered as finite entities and propagating along some distinguished direction in space in a…
