Unmixing in Random Flows
M. Wilkinson, B. Mehlig, S. Ostlund +1
We consider particles suspended in a randomly stirred or turbulent fluid. When effects of the inertia of the particles are significant, an initially uniform scatter of particles ca…
The 4(th) structure
A. Stolin, J. Yermolova-Magnusson
In this paper we describe all Lie bialgebra structures on the polynomial Lie algebra , where is a simple, finite dimensional, complex Lie algebra. The r…
Colliding Particles in Highly Turbulent Flows
Bernhard Mehlig, Ville Uski, Michael Wilkinson
We discuss relative velocities and the collision rate of small particles suspended in a highly turbulent fluid. In the limit where the viscous damping is very weak, we estimate the…
Persistent currents through a quantum impurity: Protection through integrability
Johan Nilsson, H. -P. Eckle, Henrik Johannesson
We consider an integrable model of a one-dimensional mesoscopic ring with the conduction electrons coupled by a spin exchange to a magnetic impurity. A symmetry analysis based on a…
A general asymptotic scheme for inference under order restrictions
D. Anevski, O. Hössjer
Limit distributions for the greatest convex minorant and its derivative are considered for a general class of stochastic processes including partial sum processes and empirical pro…
Radon transform on real, complex and quaternionic Grassmannians
Genkai Zhang
Let $G_{n,k}(\bbK)$ be the Grassmannian manifold of -dimensional $\bbK$-subspaces in $\bbK^n$ where $\bbK=\mathbb R, \mathbb C, \mathbb H$ is the field of real, complex or quate…
QPOs in microquasars: the spin problem
Gabriel Torok, Marek A. Abramowicz, Zdenek Stuchlik +1
In the Galactic microquasars with double peak kHz quasi-periodic oscillations (QPOs), the ratio of the two frequencies is 3:2. This supports the suggestion that double peak kHz QPO…
Joule Heating and Current-Induced Instabilities in Magnetic Nanocontacts
A. Kadigrobov, S. I. Kulinich, R. I. Shekhter +2
We consider the electrical current through a magnetic point contact in the limit of a strong inelastic scattering of electrons. In this limit local Joule heating of the contact reg…
Strength distribution of repeatedly broken chains
Michael Wilkinson, Bernhard Mehlig
We determine the probability distribution of the breaking strength for chains of N links, which have been produced by repeatedly breaking a very long chain.
Bergman kernels and equilibrium measures for polarized pseudoconcave domains
Robert Berman
Let X be a strictly pseudoconcave domain in a closed polarized complex manifold (Y,L) where L is a (semi-)positive line bundle over Y. Any given Hermitian metric on L, together wit…
Local Spectral Weight of a Luttinger Liquid: Effects from Edges and Impurities
Paata Kakashvili, Henrik Johannesson, Sebastian Eggert
We calculate the finite-temperature local spectral weight (LSW) of a Luttinger liquid with an "open" (hard wall) boundary. Close to the boundary the LSW exhibits characteristic osc…
Theoretical study of position-dependent defect formation in a single-walled carbon nanotube: Stability towards an open end
Feng Ding
Point defects, including atom vacancy, add atom and Stone-Wale defect, close to a (5, 5) single-walled carbon nanotube (SWNT) end were studied by DFT, semi-empirical PM3 method and…
The role of the catalytic particle temperature gradient for SWNT growth from small particles
Feng Ding, Arne Rosen, Kim Bolton
The Vapour-Liquid-Solid (VLS) model, which often includes a temperature gradient (TG) across the catalytic metal particle, is often used to describe the nucleation and growth of ca…
Molecular Dynamics Study of Bamboo-like Carbon Nanotube Nucleation
Feng Ding, Kim Bolton, Arne Rosen
MD simulations based on an empirical potential energy surface were used to study the nucleation of bamboo-like carbon nanotubes (BCNTs). The simulations reveal that inner walls of…
Dependence of SWNT Growth Mechanism on Temperature and Catalyst Particle Size: Bulk versus Surface Diffusion
Feng Ding, Arne Rosen, Kim Bolton
MD simulations reveal that many aspects of SWNT nucleation and growth from solid and liquid metal particles are similar. In both cases graphitic islands lift off the cluster surfac…
Precision bond lengths for Rydberg Matter clusters KN (N = 19, 37, 61 and 91) in excitation levels n = 4 - 8 from rotational radio-frequency emission spectra
Leif Holmlid
Clusters of the electronically excited condensed matter Rydberg Matter (RM) are planar and six-fold symmetric with magic numbers N = 7, 19, 37, 61 and 91. The bond distances in the…
Electronic Aharonov-Bohm Effect Induced by Quantum Vibrations
R. I. Shekhter, L. Y. Gorelik, L. I. Glazman +1
Mechanical displacements of a nanoelectromechanical system (NEMS) shift the electron trajectories and hence perturb phase coherent charge transport through the device. We show theo…
On static shells and the Buchdahl inequality for the spherically symmetric Einstein-Vlasov system
Hakan Andreasson
In a previous work \cite{An1} matter models such that the energy density and the radial- and tangential pressures and satisfy were c…
Magnetic unipolar features in con- ductivity of point contacts between normal and ferromagnetic d-metals (Co, Ni, Fe)
Yu. G. Naidyuk, I. K. Yanson, D. L. Bashlakov +6
In nanocontacts between normal and ferromagnetic metals (N--F) abrupt changes of the order of 1% are detected in differential resistance, dV/dI(V), versus bias voltage, V, on achie…
On the Buchdahl inequality for spherically symmetric static shells
Hakan Andreasson
A classical result by Buchdahl \cite{Bu1} shows that for static solutions of the spherically symmetric Einstein-matter system, the total ADM mass M and the area radius R of the bou…
Boundary Green's Function for Spin-Incoherent Interacting Electrons in One Dimension
Paata Kakashvili, Henrik Johannesson
The spin-incoherent regime of one-dimensional electrons has recently been explored using the Bethe ansatz and a bosonized path integral approach, revealing that the spin incoherenc…
Caustic activation of rain showers
Michael Wilkinson, Bernhard Mehlig, Vlad Bezuglyy
We show quantitatively how the collision rate of droplets of visible moisture in turbulent air increases very abruptly as the intensity of the turbulence passes a threshold, due to…

M. N. Kiselev, K. Kikoin, R. I. Shekhter +1
We investigate theoretically a mechanically assisted Kondo effect and electric charge shuttling in nanoelectromechanical single-electron transistor (NEM-SET). It is shown that the…

Gabriel Torok, Marek A. Abramowicz, Wlodek Kluzniak +1
Kilohertz Quasi-Periodic Oscillations (QPOs) have been detected in many accreting X-ray binaries. It has been suggested that the highest QPO frequencies observed in the modulation…
