LocalField Correction Function Of The Fermi System With A ShortRange Interaction
"... this paper we want to investigate influence of the interaction potential on the localfield correction function and other model characteristics. We shall use the reference system approach for investigation a model with a nonCoulomb interaction potential between particles. We consider the degenerate ..."

Canonical and Microcanonical Calculations for Fermi Systems
, 2008
"... Recursion relations are presented that allow exact calculation of canonical and microcanonical partition functions of degenerate Fermi systems, assuming no explicit twobody interactions. Calculations of the level density, sorted by angular momentum, are presented for 56Ni. The issue of treating unb ..."

Viewdependent simplification of arbitrary polygonal environments
, 1997
"... Hierarchical dynamic simplification (HDS) is a new approach to the problem of simplifying arbitrary polygonal environments. HDS operates dynamically, retessellating the scene continuously as the user’s viewing position shifts, and adaptively, processing the entire database without first decomposing ..."

HDS supports various preprocessing algorithms and various runtime criteria, providing a general framework for dynamic
Symplectic reflection algebras, CalogeroMoser space, and deformed HarishChandra homomorphism
 Invent. Math
"... To any finite group Γ ⊂ Sp(V) of automorphisms of a symplectic vector space V we associate a new multiparameter deformation, Hκ, of the algebra C[V]#Γ, smash product of Γ with the polynomial algebra on V. The parameter κ runs over points of CP r, where r = number of conjugacy classes of symplectic ..."

reflections in Γ. The algebra Hκ, called a symplectic reflection algebra, is expected to be related to the coordinate ring of a universal Poisson deformation of the quotient singularity V/Γ. If Γ is the Weyl group of a root system in a vector space h and V = h ⊕ h ∗ , then the algebras Hκ are certain
A Theory of SingleViewpoint Catadioptric Image Formation
 International Journal of Computer Vision
, 1999
"... Conventional video cameras have limited fields of view which make them restrictive for certain applications in computational vision. A catadioptric sensor uses a combination of lenses and mirrors placed in a carefully arranged configuration to capture a much wider field of view. One important design ..."

Theory of ultracold atomic Fermi gases
 Rev. Mod. Phys
"... The physics of quantum degenerate atomic Fermi gases in uniform as well as in harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is given to the effect of interactions which play a crucial role, bringing the gas into a superfluid phase at low temperature. In the ..."

A Pivoting Algorithm for Convex Hulls and Vertex Enumeration of Arrangements and Polyhedra
, 1990
"... We present a new piv otbased algorithm which can be used with minor modification for the enumeration of the facets of the convex hull of a set of points, or for the enumeration of the vertices of an arrangement or of a convex polyhedron, in arbitrary dimension. The algorithm has the following prope ..."

Thermal Conductivity of Fermi Particle Systems

An interpolation formula for the coefficient of thermal conductivity valid in the entire region of temperature is derived for Fermi gases on the basis uf the general quantum· statistical expression in terms of the timedependent correlation function. The formula for the conductivity gives the temper ..."

This study can be relevant for massive neutrinos in Dark Matter models and for collisionless selfgravitating systems experiencing a “violent relaxation”. Below a critical energy (in the m ..."
