Weak antilocalization in quantum wells in tilted magnetic fields
G. M. Minkov, A. V. Germanenko, O. E. Rut +4
Weak antilocalization is studied in an InGaAs quantum well. Anomalous magnetoresistance is measured and described theoretically in fields perpendicular, tilted and parallel to the…
Quantum Shuttle Phenomena in a Nanoelectromechanical Single-Electron Transistor
D. Fedorets, L. Y. Gorelik, R. I. Shekhter +1
An analytical analysis of quantum shuttle phenomena in a nanoelectromechanical single-electron transistor has been performed in the realistic case, when the electron tunnelling len…
Coagulation by Random Velocity Fields as a Kramers Problem
B. Mehlig, M. Wilkinson
We analyse the motion of a system of particles suspended in a fluid which has a random velocity field. There are coagulating and non-coagulating phases. We show that the phase tran…
Poincare series and zeta function for an irreducible plane curve singularity
Jan Stevens
The Poincare series of an irreducible plane curve singularity equals the zeta function of its monodromy, by a result of Campillo, Delgado and Gusein-Zade. We derive this fact from…
On Warnaar's elliptic matrix inversion and Karlsson-Minton-type elliptic hypergeometric series
Hjalmar Rosengren, Michael Schlosser
Using Krattenthaler's operator method, we give a new proof of Warnaar's recent elliptic extension of Krattenthaler's matrix inversion. Further, using a theta function identity clos…
Finite automata and pattern avoidance in words
Petter Brändén, Toufik Mansour
We say that a word on a totally ordered alphabet avoids the word if there are no subsequences in order-equivalent to . In this paper we suggest a new approach to the…
Dynamical Yang-Baxter equations, quasi-Poisson homogeneous spaces, and quantization
Eugene Karolinsky, Kolya Muzykin, Alexander Stolin +1
This paper is a continuation of [KS]. We develop the results of [KS] principally in two directions. First, we generalize the main result of [KS], the connection between the solutio…
On the congruence ax+by = 1 modulo xy
J. Brzezinski, W. Holsztynski, P. Kurlberg
We give bounds on the number of solutions to the Diophantine equation (X+1/x)(Y+1/y) = n as n tends to infinity. These bounds are related to the number of solutions to congruences…
Propagation of non-linear circularly polarised Alfven waves in a homogeneous medium
Rim Turkmani, Ulf Torkelsson
We study the evolution of non-linear circularly polarised Alfven waves by solving numerically the time-dependent equations of magnetohydrodynamics (MHD) in one dimension. We examin…
On the Quantum Phase Operator for Coherent States
Bo-Sture K. Skagerstam, Bjorn A. Bergsjordet
In papers by Lynch [Phys. Rev. A41, 2841 (1990)] and Gerry and Urbanski [Phys. Rev. A42, 662 (1990)] it has been argued that the phase-fluctuation laser experiments of Gerhardt, Bü…
Van der Waals interactions of parallel and concentric nanotubes
Elsebeth Schroder, Per Hyldgaard
For sparse materials like graphitic systems and carbon nanotubes the standard density functional theory (DFT) faces significant problems because it cannot accurately describe the v…
Chiral SU(N) Gauge Theories and the Konishi Anomaly
Riccardo Argurio, Gabriele Ferretti, Rainer Heise
We study chiral SU(N) supersymmetric gauge theories with matter in the antifundamental and antisymmetric representations. For SU(5) with two families, we show how to reproduce the…
The problem of the pawns
S. Kitaev, T. Mansour
In this paper we study the number of ways to place nonattacking pawns on an chessboard. We find an upper bound for and analyse its asymptotic behavi…
Berezin transform on the quantum unit ball
D. Shklyarov, G. Zhang
We introduce and study, in the framework of a theory of quantum Cartan domains, a q-analogue of the Berezin transform on the unit ball. We construct q-analogues of weighted Bergman…
Application of the Bogolyubov's theory of weakly non-ideal Bose gas on the A+A, A+B, B+B reaction-diffusion system
Zoran Konkoli
Theoretical methods for dealing with diffusion-controlled reactions inevitably rely on some kind of approximation and to find the one that works on a particular problem is not alwa…
The path-coalescence transition and its applications
M. Wilkinson, B. Mehlig
We analyse the motion of a system of particles subjected a random force fluctuating in both space and time, and experiencing viscous damping. When the damping exceeds a certain thr…
Elliptic U(2) quantum group and elliptic hypergeometric series
Erik Koelink, Yvette van Norden, Hjalmar Rosengren
We investigate an elliptic quantum group introduced by Felder and Varchenko, which is constructed from the -matrix of the Andrews-Baxter-Forrester model, containing both spectra…
Theory for structure and bulk-modulus determination
Eleni Ziambaras, Elsebeth Schroder
A new method for direct evaluation of both crystalline structure, bulk modulus B_0, and bulk-modulus pressure derivative B'_0 of solid materials with complex crystal structures is…
Summations and transformations for multiple basic and elliptic hypergeometric series by determinant evaluations
Hjalmar Rosengren, Michael Schlosser
Using multiple q-integrals and a determinant evaluation, we establish a multivariable extension of Bailey's nonterminating 10-phi-9 transformation. From this result, we deduce new…
Non-equilibrium Plasmons in a Quantum Wire Single Electron Transistor
Jaeuk U. Kim, Ilya V. Krive, Jari M. Kinaret
We analyze a single electron transistor composed of two semi-infinite one dimensional quantum wires and a relatively short segment between them. We describe each wire section by a…
On operators on polynomials preserving real-rootedness and the Neggers-Stanley Conjecture
Petter Brändén
We refine a technique used in a paper by Schur on real-rooted polynomials. This amounts to an extension of a theorem of Wagner on Hadamard products of Toeplitz matrices. We also ap…
Continuous Hahn functions as Clebsch-Gordan coefficients
Wolter Groenevelt, Erik Koelink, Hjalmar Rosengren
An explicit bilinear generating function for Meixner-Pollaczek polynomials is proved. This formula involves continuous dual Hahn polynomials, Meixner-Pollaczek functions, and non-p…
N-body simulations with two-orders-of-magnitude higher performance using wavelets
Alessandro B. Romeo, Cathy Horellou, Joeran Bergh
Noise is a problem of major concern for N-body simulations of structure formation in the early Universe, of galaxies and plasmas. Here for the first time we use wavelets to remove…
The pair approach applied to kinetics in restricted geometries: strengths and weaknesses of the method
Z. Konkoli, A. Karlsson, O. Orwar
In the rapidly emerging field of nanotechnology, as well as in biology where chemical reaction phenomena take place in systems with characteristic length scales ranging from microm…
