Band structure of CuMnAs probed by optical and photoemission spectroscopy
M. Veis, J. Minar, G. Steciuk +19
Tetragonal phase of CuMnAs progressively appears as one of the key materials for antiferromagnetic spintronics due to efficient current-induced spin-orbit torques whose existence c…
Magnetic Compton profiles of disordered FeNi and ordered FeNi alloys
D. Benea, J. Minár, H. Ebert +1
We study the magnetic Compton profile (MCP) of the disordered FeNi and of the ordered FeNi alloys and discuss the interplay between structural disorder and electron…
On semiregularity of mappings
R. Cibulka, M. Fabian, A. Y. Kruger
There are two basic ways of weakening the definition of the well-known metric regularity property by fixing one of the points involved in the definition. The first resulting proper…
Thermal conductivity and electrical resistivity of solid iron at Earth's core conditions from first-principles
Junqing Xu, Peng Zhang, K. Haule +4
We compute the thermal conductivity and electrical resistivity of solid hcp Fe to pressures and temperatures of Earth's core. We find significant contributions from electron-electr…
3-coloring triangle-free planar graphs with a precolored 9-cycle
Ilkyoo Choi, Jan Ekstein, Přemysl Holub +1
Given a triangle-free planar graph G and a 9-cycle C in G, we characterize situations where a 3-coloring of C does not extend to a proper 3-coloring of G. This extends previous res…
Note on list star edge-coloring of subcubic graphs
Borut Lužar, Martina Mockovčiaková, Roman Soták
{\emph A star edge-coloring} of a graph is a proper edge-coloring without bichromatic paths and cycles of length four. In this paper, we consider the list version of this coloring…
Finite lifetime broadening of calculated x-ray absorption spectra: possible artefacts close to the edge
Ondrej Sipr, Jiri Vackar, Jan Minar
X-ray absorption spectra calculated within an effective one-electron approach have to be broadened to account for the finite lifetime of the core hole. For Green's function based m…
Space Subdivision to Speed-up Convex Hull Construction in E3
Vaclav Skala, Zuzana Majdisova, Michal Smolik
Convex hulls are fundamental geometric tools used in a number of algorithms. This paper presents a fast, simple to implement and robust Smart Convex Hull (S-CH) algorithm for compu…
Fast Algorithm for Finding Maximum Distance with Space Subdivision in E2
Vaclav Skala, Zuzana Majdisova
Finding an exact maximum distance of two points in the given set is a fundamental computational problem which is solved in many applications. This paper presents a fast, simple to…
A two-level approach to implicit surface modeling with compactly supported radial basis functions
Rongjiang Pan, Vaclav Skala
We describe a two-level method for computing a function whose zero-level set is the surface reconstructed from given points scattered over the surface and associated with surface n…
RBF Interpolation with CSRBF of Large Data Sets
Vaclav Skala
This contribution presents a new analysis of properties of the interpolation using Radial Bases Functions (RBF) related to large data sets interpolation. The RBF application is con…
Continuous Global Optimization in Surface Reconstruction from an Oriented Point Cloud
Rongjiang Pan, Vaclav Skala
We introduce a continuous global optimization method to the field of surface reconstruction from discrete noisy cloud of points with weak information on orientation. The proposed m…
Operando imaging of all-electric spin texture manipulation in ferroelectric and multiferroic Rashba semiconductors
J. Krempaský, S. Muff, J. Minár +9
The control of the electron spin by external means is a key issue for spintronic devices. Using spin- and angle-resolved photoemission spectroscopy (SARPES) with three-dimensional…
Long paths and toughness of k-trees and chordal planar graphs
Adam Kabela
We show that every -tree of toughness greater than is Hamilton-connected for . (In particular, chordal planar graphs of toughness greater than are Ha…
On a property of the nodal set of least energy sign-changing solutions for quasilinear elliptic equations
Vladimir Bobkov, Sergei Kolonitskii
In this note we prove the Payne-type conjecture about the behaviour of the nodal set of least energy sign-changing solutions for the equation in bounded Steiner sym…
Virtual Relationships: Short- and Long-run Evidence from BitCoin and Altcoin Markets
Pavel Ciaian, Miroslava Rajcaniova, d'Artis Kancs
This study empirically examines interdependencies between BitCoin and altcoin markets in the short- and long-run. We apply time-series analytical mechanisms to daily data of 17 vir…
On the higher Cheeger problem
Vladimir Bobkov, Enea Parini
We develop the notion of higher Cheeger constants for a measurable set . By the -th Cheeger constant we mean the value \[h_k(Ω) = \inf \max \{h_1(E_1), \d…

J. Sánchez-Barriga, M. Battiato, M. Krivenkov +9
Using time-, spin- and angle-resolved photoemission, we investigate the ultrafast spin dynamics of hot electrons on the surface of the topological insulator BiTe following…
The Fredholm alternative for the -Laplacian in exterior domains
Pavel Drabek, Ky Ho, Abhishek Sarkar
We investigate the Fredholm alternative for the -Laplacian in an exterior domain which is the complement of the closed unit ball in (). By employing tech…
