A converse to the Schwarz lemma for planar harmonic maps
Ole Fredrik Brevig, Joaquim Ortega-Cerdà, Kristian Seip
A sharp version of a recent inequality of Kovalev and Yang on the ratio of the and norms for certain polynomials is obtained. The inequality is applied to establ…
Formation of light (anti)nuclei
J. Tjemsland
The production mechanism of light nuclei, such as deuteron, helium-3, tritium and their antiparticles, has recently attracted an increased attention from the astroparticle and heav…
An integral model based on slender body theory, with applications to curved rigid fibers
Helge I. Andersson, Elena Celledoni, Laurel Ohm +2
We propose a novel integral model describing the motion of curved slender fibers in viscous flow, and develop a numerical method for simulating dynamics of rigid fibers. The model…
Size distribution of emitted energies in local load sharing fiber bundles
Subhadeep Roy, Soumyajyoti Biswas
We study the local load sharing fiber bundle model and its energy burst statistics. While it is known that the avalanche size distribution of the model is exponential, we numerical…
Waves of maximal height for a class of nonlocal equations with inhomogeneous symbols
Hung Le
In this paper, we consider a class of nonlocal equations where the convolution kernel is given by a Bessel potential symbol of order for . Based on the properties of the…
Physics guided machine learning using simplified theories
Suraj Pawar, Omer San, Burak Aksoylu +2
Recent applications of machine learning, in particular deep learning, motivate the need to address the generalizability of the statistical inference approaches in physical sciences…
Identifying the origin of the non-monotonic thickness dependence of spin-orbit torques and interfacial Dzyaloshinskii-Moriya interaction in a ferrimagnetic insulator heterostructure
Shilei Ding, Lorenzo Baldrati, Andrew Ross +7
Electrical manipulation of magnetism via spin-orbit torques (SOTs) promises efficient spintronic devices. In systems comprising magnetic insulators and heavy metals, SOTs have star…
Thermally induced spin torque and domain wall motion in superconductor/antiferromagnetic insulator bilayers
G. A. Bobkov, I. V. Bobkova, A. M. Bobkov +1
We theoretically investigate domain wall motion in an antiferromagnetic insulator layer caused by thermally generated spin currents in an adjacent spin-split superconductor layer.…
Intermolecular interactions in optical cavities: an ab initio QED study
Tor S. Haugland, Christian Schäfer, Enrico Ronca +2
Intermolecular bonds are weak compared to covalent bonds, but they are strong enough to influence the properties of large molecular systems. In this work, we investigate how strong…
Nanothermodynamic description and molecular simulation of a single-phase fluid in a slit pore
Olav Galteland, Dick Bedeaux, Signe Kjelstrup
We describe the thermodynamic state of a highly confined single-phase and single-component fluid in a slit pore using Hill's thermodynamics of small systems. This theory was more r…
Mesh Denoising and Inpainting using the Total Variation of the Normal and a Shape Newton Approach
Lukas Baumgärtner, Ronny Bergmann, Roland Herzog +3
We present a novel approach to denoising and inpainting problems for surface meshes. The purpose of these problems is to remove noise or fill in missing parts while preserving impo…
Light-induced Dzyaloshinskii-Moriya interactions in antiferromagnetic metals
Sander Ø. Hanslin, Alireza Qaiumzadeh
The Dzyaloshinskii-Moriya (DM) interaction plays an essential role in novel topological spintronics, and the ability to control this chiral interaction is of key importance. Develo…
Magnetic Field Energy Harvesting in Railway
Asbjørn Engmark Espe, Thomas S. Haugan, Geir Mathisen
Magnetic field energy harvesting (MFEH) is a method by which a system can harness an ambient, alternating magnetic field in order to scavenge energy. Presented in this article is a…
Generalized iterated-sums signatures
Joscha Diehl, Kurusch Ebrahimi-Fard, Nikolas Tapia
We explore the algebraic properties of a generalized version of the iterated-sums signature, inspired by previous work of F.~Király and H.~Oberhauser. In particular, we show how to…
Quark, pion and axial condensates in three-flavor finite isospin chiral perturbation theory
Prabal Adhikari, Jens O. Andersen, Martin A. Mojahed
We calculate the light quark condensate, the strange quark condensate, the pion condensate, and the axial condensate in three-flavor chiral perturbation theory (PT) in the prese…
A Multidisciplinary Definition of Privacy Labels: The Story of Princess Privacy and the Seven Helpers
Johanna Johansen, Tore Pedersen, Simone Fischer-Hübner +6
Privacy is currently in distress and in need of rescue, much like princesses in the all-familiar fairytales. We employ storytelling and metaphors from fairytales to make reader-fri…
Dynamics of collective action to conserve a large common-pool resource
David Andersson, Sigrid Bratsberg, Andrew K. Ringsmuth +1
A pressing challenge for coming decades is sustainable and just management of large-scale common-pool resources including the atmosphere, biodiversity and public services. This pos…
Contact-free reversible switching of improper ferroelectric domains by electron and ion irradiation
Erik D. Roede, Aleksander B. Mosberg, Donald M. Evans +4
Focused ion beam (FIB) and scanning electron microscopy (SEM) are used to reversibly switch improper ferroelectric domains in the hexagonal manganite ErMnO. Surface charging is…
Thermal effects and spontaneous frictional relaxation in atomically thin layered materials
J Roadnight Sheehan, David Andersson, Astrid S. de Wijn
We study the thermal effects on the frictional properties of atomically thin sheets. We simulate a simple model based on the Prandtl-Tomlinson model that reproduces the layer depen…
Enhancement of Proximity Induced Superconductivity in a Planar Ge Hole Gas
Kushagra Aggarwal, Andrea Hofmann, Daniel Jirovec +9
Hole gases in planar germanium can have high mobilities in combination with strong spin-orbit interaction and electrically tunable g-factors, and are therefore emerging as a promis…
Cross-sublattice Spin Pumping and Magnon Level Attraction in van der Waals Antiferromagnets
Roberto E. Troncoso, Mike A. Lund, Arne Brataas +1
We theoretically study spin pumping from a layered van der Waals antiferromagnet in its canted ground state into an adjacent normal metal. We find that the resulting dc spin pumpin…
