Numerical Study of Periodic Instanton Configurations in Two-dimensional Abelian Higgs Theory
Numerical minimization of the Euclidean action of the two-dimensional Abelian
Higgs model is used to construct periodic instantons, the euclidean field
configurations with two turning points describing transitions between the
vicinities of topologically distinct vacua. Periodic instantons are found at
any energy ( up to the sphaleron energy ) and for wide range of
parameters of the theory. We obtain the dependence of the action and the energy
of periodic instanton on its period; these quantities directly determine the
probability of certain multiparticle scattering events.Comment: 8 pages, 6 figures available upon request, LaTeX, ITP-SB-92-7
The Significance of Non-ergodicity Property of Statistical Mechanics Systems for Understanding Resting State of a Living Cell
A better grasp of the physical foundations of life is necessary before we can
understand the processes occurring inside a living cell. In his physical theory
of the cell, American physiologist Gilbert Ling introduced an important notion
of the resting state of the cell. He describes this state as an independent
stable thermodynamic state of a living substance in which it has stored all the
energy it needs to perform all kinds of biological work. This state is
characterised by lower entropy of the system than in an active state. However,
Ling's approach is primarily qualitative in terms of thermodynamics and it
needs to be characterised more specifically. To this end, we propose a new
thermodynamic approach to studying Ling's model of the living cell (Ling's
cell), the center piece of which is the non-ergodicity property which has
recently been proved for a wide range of systems in statistical mechanics [7].
These approach allowed us to develop general thermodynamic approaches to
explaining some of the well-known physiological phenomena, which can be used
for further physical analysis of these phenomena using specific physical
models
Search for Standard Higgs Boson at Supercolliders
We review the standard Higgs boson physics and the search for higgs boson at
LEP and LHC supercollidersComment: latex, 70 pages, 15 ps.figure
Schlesinger system, Einstein equations and hyperelliptic curves
We review recent developments in the method of algebro-geometric integration
of integrable systems related to deformations of algebraic curves. In
particular, we discuss the theta-functional solutions of Schlesinger system,
Ernst equation and self-dual SU(2)-invariant Einstein equations.Comment: dedicated to the memory of Moshe Flat
Search for new physics at LHC
We review the search for new physics to be performed at the Large Hadron
Collider(LHC). Namely, we review the expectations for the Higgs boson,
supersymmetry and exotica detection at LHC. We also describe the main
parameters of the CMS and ATLAS detectors.Comment: 93 pages, 31 figures, added reference
