Average norms of polynomials
T. Mansour
In this paper we study the average $\NL_{2α}$-norm over -polynomials, where is a positive integer. More precisely, we present an explicit formula for the average $\NL_{2α}$-…
Intrinsic tunneling spectra of Bi_2(Sr_{2-x}La_x)CuO_6
A. Yurgens, D. Winkler, T. Claeson +2
We have measured intrinsic-tunneling spectra of a single CuO-layer La-doped Bi_2Sr_{2-x}La_xCuO_{6+δ} (Bi2201-La_x). Despite a difference of a factor of three in the optimal superc…
Quantum Precursor of Shuttle Instability
D. Fedorets, L. Y. Gorelik, R. I. Shekhter +1
The effects of a coupling between the quantized mechanical vibrations of a quantum dot and coherent tunneling of electrons through a single level in the dot are studied. The equati…
A new list of extra-galactic radio jets
F. K. Liu, Y. H. Zhang
A catalogue of extra-galactic jets is very useful both in observational and theoretical studies of active galaxies. With the use of new powerful radio instruments, the detailed str…
Black hole mass and binary model for BL Lac object OJ 287
F. K. Liu, Xue-Bing Wu
Recent intensive observations of the BL Lac object OJ 287 raise a lot of questions on the models of binary black holes, processing jets, rotating helical jets and thermal instabili…
Classical self-dual strings in d=6, (2,0) theory from afar
Andreas Gustavsson
We show how one can get solitonic strings in a six-dimensional (2,0) supersymmetric theory by incorporating a nonlinear interaction term. We derive a zero force condition between p…
Capacitively coupled hot-electron nanobolometer as far-infrared photon counter
Dragos-Victor Anghel, Leonid Kuzmin
We show theoretically that hot-electron nanobolometers consisting of a small piece of normal metal, capacitively coupled to a superconducting antenna through a pair of normal metal…
Proper Motions in Compact Symmetric Objects
A. G. Polatidis, J. E. Conway
We discuss recent measurements of proper motions of the hotspots of Compact Symmetric Objects. Source expansion has been detected in ten CSOs so far and all these objects are very…
An M-theory solution generating technique and SL(2,R)
Henric Larsson
In this paper we generalize the O(p+1,p+1) solution generating technique (this is a method used to deform Dp-branes by turning on a NS-NS B-field) to M-theory, in order to be able…
Baryonic Corrections to Superpotentials from Perturbation Theory
Riccardo Argurio, Vanicson L. Campos, Gabriele Ferretti +1
We study the corrections induced by a baryon vertex to the superpotential of SQCD with gauge group SU(N) and N quark flavors. We first compute the corrections order by order using…
Electrical Manipulation of Nanomagnets
L. Y. Gorelik, R. I. Shekhter, V. Vinokur +3
We demonstrate a possibility to manipulate the magnetic coupling between two nanomagnets with a help of ac electric field. In the scheme suggested the magnetic coupling in question…
Existence of CMC and constant areal time foliations in T^2 symmetric spacetimes with Vlasov matter
Hakan Andreasson, Alan D. Rendall, Marsha Weaver
The global structure of solutions of the Einstein equations coupled to the Vlasov equation is investigated in the presence of a two-dimensional symmetry group. It is shown that the…
Open and Winding Membranes, Affine Matrix Theory and Matrix String Theory
Martin Cederwall
We examine the structure of winding toroidal and open cylindrical membranes, especially in cases where they are stretched between boundaries. Non-zero winding or stretching means t…
Full frequency voltage noise spectral density of a single electron transistor
Andreas Kack, Goran Johansson, Goran Wendin
We calculate the full frequency spectral density of voltage fluctuations in a Single Electron Transistor (SET), used as an electrometer biased above the Coulomb threshold so that t…
Charged multifluids in general relativity
Mattias Marklund, Peter K. S. Dunsby, Gerold Betschart +2
The exact 1+3 covariant dynamical fluid equations for a multi-component plasma, together with Maxwell's equations are presented in such a way as to make them suitable for a gauge-i…
Analytical approach to electromagnetic processes in loosely bound nuclei: application to 8B
C. Forssen, N. B. Shulgina, M. V. Zhukov
In this paper we develop an analytical model in order to study electromagnetic processes involving loosely bound neutron--rich and proton--rich nuclei. We construct a model wave fu…
Observations of the neutral gas and dust in the radio galaxy 3C305
N. Jackson, R. Beswick, A. Pedlar +4
We present MERLIN and Hubble Space Telescope (HST) observations of the central region of the nearby radio galaxy 3C305 and use them to study the gas and dust in this object. The ME…
On the spatial structure of anomalously localised states in disordered conductors
V. Uski, B. Mehlig, M. Schreiber
We study the spatial structure of wave functions with exceptionally high local amplitudes in the Anderson model of localisation. By means of exact diagonalisations of finite system…
Restricted 132-alternating permutations and Chebyshev polynomials
T. Mansour
A permutation is said to be \emph{alternating} if it starts with rise and then descents and rises come in turn. In this paper we study the generating function for the number of alt…
Partially Ordered generalized patterns and k-ary words
S. Kitaev, T. Mansour
Recently, Kitaev [Ki2] introduced partially ordered generalized patterns (POGPs) in the symmetric group, which further generalize the generalized permutation patterns introduced by…
Local Magnetic Susceptibility of the Positive Muon in the Quasi 1D S=1/2 Antiferromagnet KCuF
J. Chakhalian, R. F. Kiefl, R. Miller +7
We report muon spin rotation measurements of the local magnetic susceptibility around a positive muon in the paramagnetic state of the quasi one-dimensional spin 1/2 antiferromagne…
Exact Superpotentials for Theories with Flavors via a Matrix Integral
Riccardo Argurio, Vanicson L. Campos, Gabriele Ferretti +1
We extend and test the method of Dijkgraaf and Vafa for computing the superpotential of N=1 theories to include flavors in the fundamental representation of the gauge group. This a…
Temperature-dependence of spin-polarized transport in ferromagnet / unconventional superconductor junctions
T. Hirai, Y. Tanaka, N. Yoshida +3
Tunneling conductance in ferromagnet / unconventional superconductor junctions is studied theoretically as a function of temperatures and spin-polarization in feromagnets. In d-wav…
Reply to the "Comment on 'Phase diagram of an impurity in the spin-1/2 chain: two channel Kondo effect versus Curie law'"
Sebastian Eggert, David P. Gustafsson, Stefan Rommer
In a comment by A.A. Zvyagin the phase diagram in our Letter [Phys. Rev. Lett. 86, 516 (2001)] was critisized of being incomplete and a new fixed point was suggested. We show that…
