Hydrodynamic approach to many-body systems: Exact conservation laws
نویسندگان
چکیده
In this paper I present a pedagogical derivation of continuity equations manifesting exact conservation laws in an interacting electronic system based on the nonequilibrium Keldysh technique. The purpose exercise is to lay groundwork for extending hydrodynamic approach transport strongly correlated systems where quasiparticle approximation and Boltzmann kinetic theory fail.

Incremental approach to strongly correlated many-body finite systems.
The transition and the Green operators of an interacting N body system are obtained from the solutions of the N-M body problem where M = 1,2,ellipsis,N-2. This is achieved via the development of a cumulative, nonperturbative approach that makes use of existing knowledge on the system when the number of interacting particles is reduced. The method is applied to four interacting Coulomb particles...
متن کاملHyperbolic Systems of Conservation Laws
Its purpose is to provide an account of some recent advances in the mathematical theory of hyperbolic systems of conservation laws in one space dimension. After a brief review of basic concepts, we describe in detail the method of wave-front tracking approximation and present some of the latest results on uniqueness and stability of entropy weak solutions. 1-Review of basic theory. This chapter...
متن کاملHyperbolic Systems of Conservation Laws
Conservation laws are first order systems of quasilinear partial differential equations in divergence form; they express the balance laws of continuum physics for media with "elastic" response, in which internal dissipation is neglected. The absence of internal dissipation is manifested in the emergence of solutions with jump discontinuities across manifolds of codimension one, representing, in...
متن کاملLocal conservation laws and the structure of the many-body localized states.
We construct a complete set of local integrals of motion that characterize the many-body localized (MBL) phase. Our approach relies on the assumption that local perturbations act locally on the eigenstates in the MBL phase, which is supported by numerical simulations of the random-field XXZ spin chain. We describe the structure of the eigenstates in the MBL phase and discuss the implications of...
متن کاملOnsager Relations and Eulerian Hydrodynamic Limit for Systems with Several Conservation Laws
We present the derivation of the hydrodynamic limit under Eulerian scaling for a general class of one-dimensional interacting particle systems with two or more conservation laws. Following Yau’s relative entropy method it turns out that in case of more than one conservation laws, in order that the system exhibit hydrodynamic behaviour, some particular identities reminiscent of Onsager’s recipro...
