NUMERICAL STUDY OF THE LOWEST ENERGY CONFIGURATIONS FOR GLOBAL STRINGANTISTRING PAIRS
, 1992
"... We investigate the lowest energy configurations for string antistring pairs at fixed separations by numerically minimizing the energy. We show that for separations smaller than a critical value, a region of false vacuum develops in the middle due to large gradient energy density. Consequently, well ..."

ON THE LOWEST ENERGY OF A 3D MAGNETIC HAMILTONIAN WITH AXISYMMETRIC POTENTIAL
"... ABSTRACT. We study the bottom of the spectrum of a magnetic hamiltonian with axisymmetric potential in R 3. The associated magnetic field is planar, unitary and nonconstant. The problem reduces to a 1D family of singular SturmLiouville operators on the halfline. We study the associated band funct ..."

functions and we compare it to the “de Gennes ” operators arising in the study of a 2D hamiltonian with monodimensional, odd and discontinuous magnetic field. We show in particular that the lowest energy is higher in dimension 3. hal00803984, version 2 16 Apr 2013 1.
KoszulTate cohomology as lowestenergy modules of noncentrally extended diffeomorphism algebras
, 2002
"... Fock modules for multidimensional Virasoro algebras (noncentral extensions of the diffeomorphism algebra vect(N)) have recently been reported. Using ideas from the antifield formalism, I construct new classes of lowestenergy modules, as cohomology groups of a certain Fock complex. The Fock constr ..."

On the Lowest Energy Nucleation Path in a Supersaturated Lattice Gas
, 2002
"... A lattice gas with nonconserved spin flip dynamics (of both nonGlauber and Glauber types) is considered at T ° Tc, the critical temperature. For arbitrary supersaturation, S, a general expression for the inverse of the nucleation rate along the lowest energy path is derived. The exponential part i ..."

Ab Initio Study of LowestEnergy Conformers of Lewis X (Lex) Trisaccharide
, 1999
"... This paper presents the first ab initio conformational study of the Galâ1,4[FucR1,3]GlcNAcâOCH3 and Galâ1,4[FucR1,3]GlcNAcâOH trisaccharides (Lewis x) in the gas phase. Their lowestenergy conformers were selected first by the MM2*SUMM conformational search technique. MM2 * relative ..."

Lowest energy states in nonrelativistic QED: atoms and ions in motion
, 2006
"... Within the framework of nonrelativisitic quantum electrodynamics we consider a single nucleus and N electrons coupled to the radiation field. Since the total momentum P is conserved, the Hamiltonian H admits a fiber decomposition with respect to P with fiber Hamiltonian H(P). A stable atom, resp. io ..."

. ion, means that the fiber Hamiltonian H(P) has an eigenvalue at the bottom of its spectrum. We establish the existence of a ground state for H(P) under (i) an explicit bound on P, (ii) a binding condition, and (iii) an energy inequality. The binding condition is proven to hold for a heavy nucleus
Energy Aware Routing for Low Energy Ad Hoc Sensor Networks
, 2002
"... The recent interest in sensor networks has led to a number of routing schemes that use the limited resources available at sensor nodes more efficiently. These schemes typically try to find the minimum energy path to optimize energy usage at a node. In this paper we take the view that always using lo ..."

lowest energy paths may not be optimal from the point of view of network lifetime and longterm connectivity. To optimize these measures, we propose a new scheme called energy aware routing that uses suboptimal paths occasionally to provide substantial gains. Simulation results are also presented
When the Lowest Energy Does Not Induce Native Structures: Parallel Minimization of MultiEnergy Values by Hybridizing Searching Intelligences
, 2012
"... Background: Protein structure prediction (PSP), which is usually modeled as a computational optimization problem, remains one of the biggest challenges in computational biology. PSP encounters two difficult obstacles: the inaccurate energy function problem and the searching problem. Even if the lowe ..."
Abstract

if the lowest energy has been luckily found by the searching procedure, the correct protein structures are not guaranteed to obtain. Results: A general parallel metaheuristic approach is presented to tackle the above two problems. Multienergy functions are employed to simultaneously guide the parallel
Author's personal copy Lowestenergy structures of 13atom binary clusters: Do icosahedral clusters exist in binary liquid alloys?
, 2007
"... Although the existence of 13atom icosahedral clusters in onecomponent closepacked undercooled liquids was predicted more than half a century ago by Frank, the existence of such icosahedral clusters is less clear in liquid alloys. We study the lowestenergy structures of 13atom AxB13x Lennard–Jon ..."
