Introduction to -tilting theory
Osamu Iyama, Idun Reiten
From the viewpoint of mutation, we will give a brief survey of tilting theory and cluster-tilting theory together with a motivation from cluster algebras. Then we will give an intr…
Temperature Dependence of the Casimir Force
Iver Brevik, Johan S. Høye
The Casimir force - at first a rather unexpected consequence of quantum electrodynamics - was discovered by Hendrik Casimir in Eindhoven in 1948. It predicts that two uncharged met…
Critical region of D-dimensional spins: Extension and analysis of the hierarchical reference theory
Enrique Lomba, Johan S. Høye
The hierarchical reference theory (HRT) is generalized to spins of dimensionality . Then its properties are investigated by both analytical and numerical evaluations for supercr…
A new angular momentum method for computing wave maps into spheres
Trygve Karper, Franziska Weber
In this paper, we present and analyze a new finite difference method for computing three dimensional wave maps into spheres. By introducing the angular momentum as an auxiliary var…
BayMeth: Improved DNA methylation quantification for affinity capture sequencing data using a flexible Bayesian approach
Andrea Riebler, Mirco Menigatti, Jenny Z. Song +6
DNA methylation (DNAme) is a critical component of the epigenetic regulatory machinery and aberrations in DNAme patterns occur in many diseases, such as cancer. Mapping and underst…
Viscosity-Induced Crossing of the Phantom Divide in the Dark Cosmic Fluid
Iver Brevik
Choosing various natural forms for the equation-of-state parameter w and the bulk viscosity ζ, we discuss how it is possible for a dark energy fluid to slide from the quintessence…
Towards Normalizing the Edit Distance Using a Genetic Algorithms Based Scheme
Muhammad Marwan Muhammad Fuad
The normalized edit distance is one of the distances derived from the edit distance. It is useful in some applications because it takes into account the lengths of the two strings…
Scalable iterative methods for sampling from massive Gaussian random vectors
Daniel P. Simpson, Ian W. Turner, Christopher M. Strickland +1
Sampling from Gaussian Markov random fields (GMRFs), that is multivariate Gaussian ran- dom vectors that are parameterised by the inverse of their covariance matrix, is a fundament…
ABC-SG: A New Artificial Bee Colony Algorithm-Based Distance of Sequential Data Using Sigma Grams
Muhammad Marwan Muhammad Fuad
The problem of similarity search is one of the main problems in computer science. This problem has many applications in text-retrieval, web search, computational biology, bioinform…
Lattice structure of torsion classes for path algebras
Osamu Iyama, Idun Reiten, Hugh Thomas +1
We consider module categories of path algebras of connected acyclic quivers. It is shown in this paper that the set of functorially finite torsion classes form a lattice if and onl…
Strong antibunching in a generalized Rabi model
Arne L. Grimsmo, Scott Parkins
We consider a generalized version of the Rabi model that includes a nonlinear, dispersive-type atom-field interaction in addition to the usual linear dipole coupling, as well as ca…
On the analysis of a coupled kinetic-fluid model with local alignment forces
J. A. Carrillo, Y. -P. Choi, T. K. Karper
This paper studies global existence, hydrodynamic limit, and large-time behavior of weak solutions to a kinetic flocking model coupled to the incompressible Navier-Stokes equations…
Little Rip and Pseudo Rip Phenomena from Coupled Dark Energy
I. Brevik, A. V. Timoshkin, Y. Rabochaya
We consider Little Rip (LR) and Pseudo Rip (PR) cosmological models with two interacting ideal fluids, corresponding to dark energy and dark matter. The interaction between the dar…
Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop
Jens O. Andersen, William R. Naylor, Anders Tranberg
We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconfinement transitions in the presence of a constant magn…
Null holomorphic curves in and the conformal Calabi-Yau problem
Antonio Alarcon, Franc Forstneric
In this paper we survey some recent contributions by the authors to the theory of null holomorphic curves in the complex Euclidean space , as well as their application…
Spin-Orbit Torques and Anisotropic Magnetization Damping in Skyrmion Crystals
Kjetil M. D. Hals, Arne Brataas
The length scale of the magnetization gradients in chiral magnets is determined by the relativistic Dzyaloshinskii-Moriya interaction. Thus, even conventional spin-transfer torques…
Stability Analysis and Classification of Runge-Kutta Methods for Index 1 Stochastic Differential-Algebraic Equations with Scalar Noise
Dominique Küpper, Anne Kværnø, Andreas Rößler
The problem of solving stochastic differential-algebraic equations (SDAEs) of index one with a scalar driving Brownian motion is considered. Recently, the authors proposed a class…
Antiferromagnetic Domain Wall Motion Induced by Spin Waves
Erlend Grytli Tveten, Alireza Qaiumzadeh, Arne Brataas
Spin waves in antiferromagnets are linearly or circularly polarized. Depending on the polarization, traversing spin waves alter the staggered field in a qualitatively different way…
Higher n-angulations from local rings
Petter Andreas Bergh, Gustavo Jasso, Marius Thaule
We show that the category of finitely generated free modules over certain local rings is n-angulated for every n at least 3. In fact, we construct several classes of n-angles, para…
How linear surface waves are affected by a current with constant vorticity
Simen Å Ellingsen, Iver Brevik
The interaction of surface waves with Couette-type current with uniform vorticity is a well suited problem for students approaching the theory of surface waves. The problem, althou…
Trimodal steady water waves
Mats Ehrnström, Erik Wahlén
We construct three-dimensional families of small-amplitude gravity-driven rotational steady water waves on finite depth. The solutions contain counter-currents and multiple crests…
Cluster categories for marked surfaces: punctured case
Yu Qiu, Yu Zhou
We study the cluster categories arising from marked surfaces (with punctures and non-empty boundaries). By constructing skewed-gentle algebras, we show that there is a bijection be…
Self-Quenching of Nuclear Spin Dynamics in Central Spin Problem
Arne Brataas, Emmanuel I. Rashba
We consider, in the framework of the central spin model, driven dynamics of two electrons in a double quantum dot subject to hyperfine interaction with nuclear spins and sp…
What Do Experiments in Optics tell us about Photon Momentum in Media?
Iver Brevik
In order to get some insight in the intricacies of the Abraham-Minkowski energy-momentum problem in phenomenological electrodynamics, we briefly analyze eight different experimenta…
