Kinetic Phenomena and Collective Modes in Highly Anisotropic Organic Conductors

Janielw — Wed, 13 Oct 2021 02:11:01 +0000

Considerable attention is paid to the phenomena that are specific to quasi-2D and Quasi-ID conductive structures and have no analogues both in ordinary metals and in truly 2D or OD conducting systems. Angular magnetoresistance oscillations, de Haas-van Alphen and Shubnikov-de Hass phenomena, and high-frequency resonances, including those arising due to the movement of electron on open trajectories, are discussed. The resonant angular oscillations of high-frequency conductivity and weakly damped electromagnetic waves in quasi-2D organic conductors under strong spatial dispersion are considered. We review high frequency collective processes in highly anisotropic conducting systems in the presence of an external magnetic field taking into account of the Fermi-liquid interaction. The specific of the quasi-two-dimensional electron energy spectrum and of the Fermi-liquid interaction in layered conductors leads to occurrence of weakly-damping eigen oscillations of the electron and spin densities which are absent in a quasi-isotropic metal

Factorized S Matrices and Lattice Statistical Systems

Janielw — Wed, 13 Oct 2021 01:59:32 +0000

Factorized S Matrices and Lattice Statistical Systems – A. B. Zamolodchikov was first published in 1980 in the series Soviet Scientific Reviews/Physics Reviews edited by I. M. Khalatnikov: Volume 2: a compiled volume.

This classic paper studies the general characteristics of relativistic factorized S-matrices in two dimensional space-time. It shows that for Euclidean values of external momenta, multiparticle elements in such S matrices formally define special model systems of lattice – statistics model systems ( S models) that have a number of characteristics in common with the Baxter eight-vertex model

Multiloop Amplitudes in The Theory of Quantum Strings and Complex Geometry

Janielw — Wed, 13 Oct 2021 01:54:01 +0000

This classic paper was first published in Soviet Scientific Reviews in 1989 and is a review of the main results in the area of multiloop calculations in the theory of strings. The evaluation of multiloop amplitudes in the theory of closed oriented Bosnic strings reduces to finding the measure on the moduli space of Riemann surfaces. It is shown that the measure is the products of the squared modulus of a holomorphic function with the determinant of the imaginary part of the period matrix to the power-13. With the help of this theorem, the measure can be expressed in terms of theta functions. A version of the holomorphity theorem (Quillen’s theorem) is used for evaluating the dependence of the determinants of the Laplace operators on the boundary conditions on the Riemann surface. In the case where the Riemann surfaces are presented as ramified covering of CPI the measure is expressible in terms of the coordinates of the ramification points, in such a way that a vertex operator corresponds to each ramification point. The measure is the correlation of the operators, so that the sum over all higher loops can be written as the statistical sum of a two-dimensional conformal field theory.
