Constraints on changes in the proton-electron mass ratio using methanol lines
N. Kanekar, W. Ubachs, K. M. Menten +6
We report Karl G. Jansky Very Large Array (VLA) absorption spectroscopy in four methanol (CHOH) lines in the gravitational lens towards PKS1830-211. Three of the…
Ultrastrong coupling in two-resonator circuit QED
A. Baust, E. Hoffmann, M. Haeberlein +17
We report on ultrastrong coupling between a superconducting flux qubit and a resonant mode of a system comprised of two superconducting coplanar stripline resonators coupled galvan…
van der Waals forces in density functional theory: The vdW-DF method
Kristian Berland, Valentino R. Cooper, Kyuho Lee +4
A density functional theory (DFT) that accounts for van der Waals (vdW) interactions in condensed matter, materials physics, chemistry, and biology is reviewed. The insights that l…
SKA studies of nearby galaxies: star-formation, accretion processes and molecular gas across all environments
R. J. Beswick, E. Brinks, M. A. Perez-Torres +15
The SKA will be a transformational instrument in the study of our local Universe. In particular, by virtue of its high sensitivity (both to point sources and diffuse low surface br…
Statistical analysis and modeling of intermittent transport events in the tokamak SOL
J. Anderson, F. Halpern, P. Xanthopoulos +2
The turbulence observed in the scrape-off-layer of a tokamak is often characterized by intermittent events of bursty nature, a feature which raises concerns about the prediction of…
The inhomogeneous ISM toward PKS1830-211 SW - A detailed view on molecular gas at a look-back time of 7.5 Gyr
A. Schulz, C. Henkel, K. M. Menten +4
Based on measurements with the Effelsberg 100-m telescope, a multi-line study of molecular species is presented toward the south-western source of the gravitational lens system PKS…
Thomas-Ehrman effect in a three-body model: Ne case
L. V. Grigorenko, T. A. Golubkova, M. V. Zhukov
The dynamic mechanism of the Thomas-Ehrman shift is studied in three-cluster systems by example of Ne and C isobaric mirror partners. We predict configuration mixings…
ALMA observations of alpha Centauri: First detection of main-sequence stars at 3mm wavelength
R. Liseau, W. Vlemmings, A. Bayo +19
The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and those of other stars constitute an active field of research.…
Characterization of precipitation in Al-Li alloy AA2195 by means of atom probe tomography and transmission electron microscopy
Muna Khushaim, Torben Boll, Judith Seibert +2
The microstructure of the commercial alloy AA2195 was investigated on the nano-scale after conducting a T8 tempering. This particular thermo-mechanical treatment of the specimen re…
Generalised Entropy MDPs and Minimax Regret
Emmanouil G. Androulakis, Christos Dimitrakakis
Bayesian methods suffer from the problem of how to specify prior beliefs. One interesting idea is to consider worst-case priors. This requires solving a stochastic zero-sum game. I…
Error Floor Analysis of Coded Slotted ALOHA over Packet Erasure Channels
Mikhail Ivanov, Fredrik Brannstrom, Alexandre Graell i Amat +1
We present a framework for the analysis of the error floor of coded slotted ALOHA (CSA) for finite frame lengths over the packet erasure channel. The error floor is caused by stopp…
Resonant surface plasmons of a metal nanosphere can be considered in the way of propagating surface plasmons
Yurui Fang, Xiaorui Tian
Assuming that the resonant surface plasmons on a spherical nanoparticle is formed by standing waves of two counter-propagating surface plasmon waves along the surface, by using Mie…
Entanglement Dynamics of Quantum Oscillators Nonlinearly Coupled to Thermal Environments
Aurora Voje, Alexander Croy, Andreas Isacsson
We study the asymptotic entanglement of two quantum harmonic oscillators nonlinearly coupled to an environment. Coupling to independent baths and a common bath are investigated. Nu…
A Ronkin type function for coamoebas
Petter Johansson, Håkan Samuelsson Kalm
The Ronkin function plays a fundamental role in the theory of amoebas. We introduce an analogue of the Ronkin function in the setting of coamoebas. It turns out to be closely relat…
Herschel Survey of Galactic OH+, H2O+, and H3O+: Probing the Molecular Hydrogen Fraction and Cosmic-Ray Ionization Rate
Nick Indriolo, D. A. Neufeld, M. Gerin +19
In diffuse interstellar clouds the chemistry that leads to the formation of the oxygen bearing ions OH+, H2O+, and H3O+ begins with the ionization of atomic hydrogen by cosmic rays…
Short-Packet Communications over Multiple-Antenna Rayleigh-Fading Channels
Giuseppe Durisi, Tobias Koch, Johan Östman +2
Motivated by the current interest in ultra-reliable, low-latency, machine-type communication systems, we investigate the tradeoff between reliability, throughput, and latency in th…
Tunneling Theory for Tunable Open Quantum Systems of Ultracold Atoms in One-Dimensional Traps
R. Lundmark, C. Forssén, J. Rotureau
The creation of tunable open quantum systems is becoming feasible in current experiments with ultracold atoms in low-dimensional traps. In particular, the high degree of experiment…
Extended PIC schemes for physics in ultra-strong laser fields: review and developments
A. Gonoskov, S. Bastrakov, E. Efimenko +7
We review common extensions of particle-in-cell (PIC) schemes which account for strong field phenomena in laser-plasma interactions. After describing the physical processes of inte…
On site percolation in random quadrangulations of the half-plane
