Searches for effects of flavor-changing neutral currents
(Elsevier, 1980-08-25)
We discuss some possible processes, mainly decays, to search for flavor-changing neutral currents. We examine the theoretical constraints from present data as well as improved sensitivities which might be achieved in future ...
Nearest-neighbor distances in diffusion-controlled reactions modelled by a single mobile trap
(Elsevier, 1991-02-15)
We consider a system consisting of an infinite number of identical particles on a lattice initially uniformly distributed, which diffuese in the presence of a singke mobile trap and ask for the time-dependent behavior of ...
Evidence for multiple scattering of high energy partons in nuclei
(Elsevier, 1991-04-18)
New experimental information is presented about the effect of a nucleus on partons which have undergone a hard scatter. We have observed clear dijet events from 400 GeV / c p-nucleus interactions and compared them to dijets ...
Erratum: Quasi-collinear and partially degenerate four-wave mixing: An alternative explanation of the phase-conjugation property of backward stimulated scattering [JETP 88, 235–245 (February 1999)]
(Nauka/Interperiodica; American Institute of Physics ; Springer Science+Business Media, 1999-06)
Renormalization of some one-space dimensional quantum field theories by unitary transformation
(Elsevier, 1971-11)
The one-space dimensional interaction is renormalized by unitary transformation. A uniformly convergent sequence of unitary operators is defined which transforms the sequence of cut-off Hamiltonians, arranged in order of ...
Non-local exchange correlation energy in quasi-two-dimensional electron layers
(Elsevier, 1985)
We introduce a simple, non-local approximation for the exchange-correlation energy of an inhomogeneous electron gas. This approximation is shown to be quantitatively accurate in several important limiting cases. The method ...
A restricted class of exact eigenstates of the pairing-force Hamiltonian
(Elsevier, 1963-02-01)
New Realizations of the Maximal Satake Compactifications of Riemannian Symmetric Spaces of Noncompact Type
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-07)
We give new realizations of the maximal Satake compactifications of Riemannian symmetric spaces of noncompact type as orbit closures inside Grassmannians and orthogonal groups. Our constructions are partially motivated by ...
The variational problem and background fields in renormalization group method for lattice gauge theories
(Springer-Verlag, 1985-06)
We consider the action of a lattice gauge theory on a space of regular gauge field configurations with fixed averages, and we prove that there exists a minimum of this action. The minimum is unique up to gauge transformations. ...
The peak in the thermal conductivity of Cu-O superconductors: Electronic or phononic origin?
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1994-04)
The thermal conductivity К of hole-doped Cu-O plane high- T c perovskites exhibits a dramatic increase below T c which results in a pronounced peak near T c /2. The origin of this peak was initially thought to arise from ...
