Nuclear Physics Experiments with Ion Storage Rings
Yu. A. Litvinov, S. Bishop, K. Blaum +38
In the last two decades a number of nuclear structure and astrophysics experiments were performed at heavy-ion storage rings employing unique experimental conditions offered by suc…
Potential multi-component structure of the debris disk around HIP 17439 revealed by Herschel/DUNES
S. Ertel, J. P. Marshall, J. -C. Augereau +16
[abridged] Aims. Our Herschel Open Time Key Programme DUNES aims at detecting and characterizing debris disks around nearby, sun-like stars. In addition to the statistical analysis…
Transfer reactions in inverse kinematics, an experimental approach for fission investigations
C. Rodríguez-Tajes, F. Farget, X. Derkx +21
Inelastic and multi-nucleon transfer reactions between a U beam, accelerated at 6.14 MeV/u, and a C target were used for the production of neutron-rich, fissioning s…
Effects of the equilibrium model on impurity transport in tokamaks
Andreas Skyman, Luis Fazendeiro, Daniel Tegnered +3
Gyrokinetic simulations of ion temperature gradient mode and trapped electron mode driven impurity transport in a realistic tokamak geometry are presented and compared with results…
The Fundamental Manifold of spiral galaxies: ordered versus random motions and the morphology dependence of the Tully-Fisher relation
Chiara Tonini, Heath Jones, Jeremy Mould +3
(Abridged) We investigate the morphology dependence of the Tully-Fisher relation, and the expansion of the relation into a three-dimensional manifold defined by luminosity, total c…
Dust Production and Particle Acceleration in Supernova 1987A Revealed with ALMA
R. Indebetouw, M. Matsuura, E. Dwek +23
Supernova (SN) explosions are crucial engines driving the evolution of galaxies by shock heating gas, increasing the metallicity, creating dust, and accelerating energetic particle…
A Low-Complexity Detector for Memoryless Polarization-Multiplexed Fiber-Optical Channels
Christian Häger, Lotfollah Beygi, Erik Agrell +3
A low-complexity detector is introduced for polarization-multiplexed M-ary phase shift keying modulation in a fiber-optical channel impaired by nonlinear phase noise, generalizing…
A multi-stable switchable metamaterial
Philipp Jung, Susanne Butz, Michael Marthaler +4
The field of metamaterial research revolves around the idea of creating artificial media that interact with light in a way unknown from naturally occurring materials. This is commo…
Globally strongly convex cost functional for a coefficient inverse problem
Larisa Beilina, Michael V. Klibanov
A Carleman Weight Function (CWF) is used to construct a new cost functional for a Coefficient Inverse Problems for a hyperbolic PDE. Given a bounded set of an arbitrary size in a c…
Robust Constraint on a Drifting Proton-to-Electron Mass Ratio at z=0.89 from Methanol Observation at Three Radio Telescopes
Julija Bagdonaite, Mario Daprà, Paul Jansen +5
A limit on a possible cosmological variation of the proton-to-electron mass ratio is derived from methanol (CHOH) absorption lines in the benchmark PKS1830211 lensing ga…
Data Structures for Task-based Priority Scheduling
Martin Wimmer, Daniel Cederman, Francesco Versaci +2
Many task-parallel applications can benefit from attempting to execute tasks in a specific order, as for instance indicated by priorities associated with the tasks. We present thre…
Nonperturbative Quantum Field Evolution
Xingbo Zhao, Anton Ilderton, Pieter Maris +1
We introduce a nonperturbative, first-principles approach to time-dependent problems in quantum field theory. In this approach, the time-evolution of quantum field configurations i…
Commutator estimates on contact manifolds and applications
Heiko Gimperlein, Magnus Goffeng
This article studies sharp norm estimates for the commutator of pseudo-differential operators with multiplication operators on closed Heisenberg manifolds. In particular, we obtain…
Comparison of particle trajectories and collision operators for collisional transport in nonaxisymmetric plasmas
Matt Landreman, Håkan M Smith, Albert Mollén +1
In this work, we examine the validity of several common simplifying assumptions used in numerical neoclassical calculations for nonaxisymmetric plasmas, both by using a new continu…
Duality in refined Sobolev-Malliavin spaces and weak approximations of SPDE
Adam Andersson, Raphael Kruse, Stig Larsson
We introduce a new family of refined Sobolev-Malliavin spaces that capture the integrability in time of the Malliavin derivative. We consider duality in these spaces and derive a B…
Towards an exact frame formulation of conformal higher spins in three dimensions
Bengt E. W. Nilsson
In this note we discuss some aspects of the frame formulation of conformal higher spins in three dimensions. We give some exact formulae for the coupled spin two - spin three part…
Fermionic UV completions of Composite Higgs models
Gabriele Ferretti, Denis Karateev
We classify the four-dimensional purely fermionic gauge theories that give a UV completion of composite Higgs models. Our analysis is at the group theoretical level, addressing the…
Propagation of chaos for the thermostatted Kac master equation
Eric Carlen, Dawan Mustafa, Bernt Wennberg
The Kac model is a simplified model of an -particle system in which the collisions of a real particle system are modeled by random jumps of pairs of particle velocities. Kac pro…
Fourier expansions of Kac-Moody Eisenstein series and degenerate Whittaker vectors
Philipp Fleig, Axel Kleinschmidt, Daniel Persson
Motivated by string theory scattering amplitudes that are invariant under a discrete U-duality, we study Fourier coefficients of Eisenstein series on Kac-Moody groups. In particula…
Multiphoton signatures of goldstini at the LHC
Gabriele Ferretti, Alberto Mariotti, Kentarou Mawatari +1
We study models of gauge mediated SUSY breaking with more than one hidden sector. In these models the neutralino sector of the MSSM is supplemented with additional light neutral fe…
Scalability of the plasma physics code GEM
Bruce D. Scott, Volker Weinberg, Olivier Hoenen +2
