Energy fluctuations, hydrodynamics and local correlations in harmonic systems with bulk noises
Energy fluctuations hydrodynamics local correlations harmonic systems Mathematical Physics
2012/6/12
In this note, I summarise and comment on joint work with C. Bernardin, V. Kannan and J. L. Lebowitz concerning two harmonic systems with bulk noises whose nonequilibrium steady states (NESS) are nearl...
A solution of the non-uniqueness problem of the Dirac Hamiltonian and energy operators
non-uniqueness problem Dirac Hamiltonian energy operators General Relativity and Quantum Cosmology
2011/10/9
Abstract: In a general spacetime, the possible choices for the field of orthonormal tetrads lead (in standard conditions) to equivalent Dirac equations. However, the Hamiltonian operator is got from r...

Absence of traveling wave solutions of conductivity type for the Novikov-Veselov equations at zero energy
traveling wave conductivity type the Novikov-Veselov equations zero energy
2011/7/27
Abstract: We prove that the Novikov-Veselov equation (an analog of KdV in dimension 2 + 1) at zero energy does not have sufficiently localized soliton solutions of conductivity type.

No-Go theorem for energy surfaces
No-Go theorem energy surfaces Concavity property Nuclear Theory
2011/7/28
Abstract: Concavity properties prevent the existence of significant landscapes in energy surfaces obtained by energy minimizations under constraints. The contradiction holds at finite temperatures T a...
Universal Theorems for Total Energy of the Dynamics of Linearly Elastic Heterogeneous Solids
Energy Bounds Effective Dynamic Properties Metamaterials Homogenization
2011/7/28
Abstract: In this paper we consider a sample of a linearly elastic heterogeneous composite in elastodynamic equilibrium and present universal theorems which provide lower bounds for the total elastic ...
A Brief Remark on Energy Conditions and the Geroch-Jang Theorem
Brief Remark Energy Conditions the Geroch-Jang Theorem
2011/7/27
Abstract: The status of the geodesic principle in General Relativity has been a topic of some interest in the recent literature on the foundations of spacetime theories. Part of this discussion has fo...
Energy density in density functional theory: Application to crystalline defects and surfaces
Energy density density functional theory crystalline defects surfaces
2010/11/25
We propose a method to decompose the total energy of a supercell containing defects into
contributions of individual atoms, using the energy density formalism within density functional
theory. The s...
We introduce the "total s-energy" of a multiagent system and bound its maximum asymptotic value. This offers a new analytical lens on bidirectional agreement dynamics. We use our results to bound the ...
Time as a Quantum Observable, Canonically Conjugated to Energy, and Foundations of Self-Consistent Time Analysis of Quantum Processes
Quantum Processes Canonically Conjugated Self-Consistent Time Analysis
2009/9/4
Recent developments are reviewed and some new results are presented in the study of time in quantum mechanics and quantum electrodynamics as an observable, canonically conjugate to energy. This paper ...
