Survival of inhomogeneous Galton-Watson processes
Erik Broman, Ronald Meester
We study survival properties of inhomogeneous Galton-Watson processes. We determine the so-called branching number (which is the reciprocal of the critical value for percolation) f…
(2,0) theory on circle fibrations
Hampus Linander, Fredrik Ohlsson
We consider (2,0) theory on a manifold M_6 that is a fibration of a spatial S^1 over some five-dimensional base manifold M_5. Initially, we study the free (2,0) tensor multiplet wh…
The Biequivalence of Locally Cartesian Closed Categories and Martin-Löf Type Theories
Pierre Clairambault, Peter Dybjer
Seely's paper "Locally cartesian closed categories and type theory" contains a well-known result in categorical type theory: that the category of locally cartesian closed categorie…
Exploring the anomaly in the interaction cross section and matter radius of 23O
R. Kanungo, A. Prochazka, M. Uchida +37
New measurements of the interaction cross sections of 22,23O at 900A MeV performed at the GSI, Darmstadt are reported that address the unsolved puzzle of the large cross section pr…
Soft nanostructuring of YBCO Josephson Junctions by phase separation
David Gustafsson, Henrik Pettersson, Beniamino Iandolo +3
We have developed a new method to fabricate biepitaxial YBa2Cu3O(7-x) (YBCO) Josephson junctions at the nanoscale, allowing junctions widths down to 100 nm and simultaneously avoid…
Drastically suppressing the error of ballistic readout of qubits
Andrey L. Pankratov, Anna V. Gordeeva, Leonid S. Kuzmin
The thermal jitter of transmission of magnetic flux quanta in long Josephson junctions is studied. While for large-to-critical damping and small values of bias current the physical…
Theory of Polar Corrections to Donor Binding
G. D. Mahan, Kristian Berland
We calculate the optical phonon correction to the binding energy of electrons to donors in cubic materials. Previous theories calculated the Rydberg energy reduced by the effective…
Noise properties of nanoscale YBCO Josephson junctions
David Gustafsson, Floriana Lombardi, Thilo Bauch
We present electric noise measurements of nanoscale biepitaxial YBa2Cu3O(7-x) (YBCO) Josephson junctions fabricated by two different lithographic methods. The first (conventional)…
Particle transport in density gradient driven TE mode turbulence
Andreas Skyman, Hans Nordman, P. I. Strand
The turbulent transport of main ion and trace impurities in a tokamak device in the presence of steep electron density gradients has been studied. The parameters are chosen for tra…
Spin controlled nanomechanics induced by single-electron tunneling
Danko Radić, Anders Nordenfelt, Anatoli M. Kadigrobov +3
We consider dc-electronic transport through a nanowire suspended between normal- and spin-polarized metal leads in the presence of an external magnetic field. We show that magnetom…
M5-branes, toric diagrams and gauge theory duality
Ling Bao, Elli Pomoni, Masato Taki +1
In this article we explore the duality between the low energy effective theory of five-dimensional N=1 SU(N)^{M-1} and SU(M)^{N-1} linear quiver gauge theories compactified on S^1.…
Collider signatures of goldstini in gauge mediation
Riccardo Argurio, Karen De Causmaecker, Gabriele Ferretti +3
We investigate the collider signatures of the multiple goldstini scenario in the framework of gauge mediation. This class of models is characterized by a visible sector (e.g. the M…
Tunneling solutions in topological field theory on R x S^3 x I
Louise Anderson, Mans Henningson
We consider a topologically twisted version, recently introduced by Witten, of five-dimensional maximally supersymmetric Yang-Mills theory on a five-manifold of the form M_5 =R x W…
Two and Three Nucleons in a Trap and the Continuum Limit
J. Rotureau, I. Stetcu, B. R. Barrett +1
We describe systems of two and three nucleons trapped in a harmonic-oscillator potential with interactions from the pionless effective field theory up to next-to-leading order (NLO…
Percolation beyond ${\mathbb{Z}}^{\bolds{d}}$: The contributions of Oded Schramm
Olle Häggström
Oded Schramm (1961-2008) influenced greatly the development of percolation theory beyond the usual setting; in particular, the case of nonamenable lattices. Here,…
Detection of HCN, HCO+ and HNC in the Mrk231 molecular outflow - Dense molecular gas in the AGN wind
S. Aalto, S. Garcia-Burillo, S. Muller +5
We detect luminous emission from HCN, HCO+ and HNC 1--0 in the QSO ULIRG Mrk~231 with the IRAM Plateau de Bure Interferometer at 1."55 by 1."28 resolution. All three lines show bro…
Production of interstellar hydrogen peroxide (H2O2) on the surface of dust grains
Fujun Du, Berengere Parise, Per Bergman
Context. The formation of water on the dust grains in the interstellar medium may proceed with hydrogen peroxide (H2O2) as an intermediate. Recently gas-phase H2O2 has been detecte…
Umklapp-Assisted Electron Transport Oscillations in Metal Superlattices
S. I. Kulinich, L. Y. Gorelik, S. A. Gredeskul +2
We consider a superlattice of parallel metal tunnel junctions with a spatially non-homogeneous probability for electrons to tunnel. In such structures tunneling can be accompanied…
The Herschel HIFI water line survey in the low-mass proto-stellar outflow L1448
G. Santangelo, B. Nisini, T. Giannini +8
As part of the WISH (Water In Star-forming regions with Herschel) key project, we report on the observations of several ortho- and para-H2O lines performed with the HIFI instrument…
Mechanical cat states in graphene resonators
A. Voje, J. M. Kinaret, A. Isacsson
We study the quantum dynamics of a symmetric nanomechanical graphene resonator with degenerate flexural modes. Applying voltage pulses to two back gates, flexural vibrations of the…
