Phase diagram of truncated tetrahedral model
Roman Krcmar, Andrej Gendiar, Tomotoshi Nishino
Phase diagram of a discrete counterpart of the classical Heisenberg model, the truncated tetrahedral model, is analyzed on the square lattice, when the interaction is ferromagnetic…
An Invitation to Quantum Incompatibility
Teiko Heinosaari, Takayuki Miyadera, Mario Ziman
In the context of a physical theory, two devices, A and B, described by the theory are called incompatible if the theory does not allow the existence of a third device C that would…
Decay in covariant quark model
Stanislav Dubnička, Anna Z. Dubničková, Nurgul Habyl +3
Our article is devoted to the study of the rare ~decay where . We compute the relevant form factors in the framework of the covariant quark mo…
Poisson-Boltzmann thermodynamics of counter-ions confined by curved hard walls
Ladislav Samaj, E. Trizac
We consider a set of identical mobile point-like charges (counter-ions) confined to a domain with curved hard walls carrying a uniform fixed surface charge density, the system as a…
Counter-Ions Near a Charged Wall: Exact Results for Disc and Planar Geometries
Ladislav Šamaj
Macromolecules, when immersed in a polar solvent like water, become charged by a fixed surface charge density which is compensated by ``counter-ions'' moving out of the surface. Su…
With string model to time series forecasting
Richard Pinčák, Erik Bartoš
Overwhelming majority of econometric models applied on a long term basis in the financial forex market do not work sufficiently well. The reason is that transaction costs and arbit…
Free Energy Analysis of Spin Models on Hyperbolic Lattice Geometries
Marcel Serina, Jozef Genzor, Yoju Lee +1
We investigate relations between spatial properties of the free energy and the radius of Gaussian curvature of the underlying curved lattice geometries. For this purpose we derive…
Incompatible measurements on quantum causal networks
Michal Sedlak, Daniel Reitzner, Giulio Chiribella +1
The existence of incompatible measurements, epitomized by Heisenberg's uncertainty principle, is one of the distinctive features of quantum theory. So far, quantum incompatibility…
An explicit classical strategy for winning a game
Matej Pivoluska, Martin Plesch
A game is a generalization of the standard two player game, having different input and output options. In contrast to the binary game, the b…
Quantum proofs can be verified using only single qubit measurements
Tomoyuki Morimae, Daniel Nagaj, Norbert Schuch
QMA (Quantum Merlin Arthur) is the class of problems which, though potentially hard to solve, have a quantum solution which can be verified efficiently using a quantum computer. It…
Topological Floquet Phases in Driven Coupled Rashba Nanowires
Jelena Klinovaja, Peter Stano, Daniel Loss
We consider periodically-driven arrays of weakly coupled wires with conduction and valence bands of Rashba type and study the resulting Floquet states. This non-equilibrium system…
Structure of Periodic Crystals and Quasicrystals in Ultrathin Film Ba-Ti-O
Eric Cockayne, Marek Mihalkovic, Christopher L. Henley
We model the remarkable thin-film Ba-Ti-O structures formed by heat treatment of an initial perovskite BaTiO thin film on a Pt(111) surface. All structures contain a rumpled Ti…
Analysis of quantum spin models on hyperbolic lattices and Bethe lattice
Michal Daniska, Andrej Gendiar
The quantum XY, Heisenberg, and transverse field Ising models on hyperbolic lattices are studied by means of the Tensor Product Variational Formulation algorithm. The lattices are…
On the Combined Analysis of Muon Shower Size and Depth of Shower Maximum
J. Vicha, P. Travnicek, D. Nosek
The mass composition of ultra-high energy cosmic rays can be studied from the distributions of the depth of shower maximum and/or the muon shower size. Here, we study the dependenc…
Effect of coupled channels of the multi-channel pion-pion scattering in two-pion transitions of the mesons
Yu. S. Surovtsev, P. Bydžovský, T. Gutsche +3
The effect of isoscalar S-wave processes is considered in the analysis of data (from the ARGUS, CLEO, CUSB, Crystal Ball, Belle, BABAR collaborations) on…
Quantum Turbulence of Bellows-Driven 4He Superflow: Decay
Simone Babuin, Emil Varga, William F. Vinen +1
We report on studies of quantum turbulence with second-sound in superfluid 4He in which the turbulence is generated by the flow of the superfluid component through a wide square ch…
Phase Transition of the Ising Model on Fractal Lattice
Jozef Genzor, Andrej Gendiar, Tomotoshi Nishino
Phase transition of the Ising model is investigated on a planar lattice that has a fractal structure. On the lattice, the number of bonds that cross the border of a finite area is…
Antiferromagnetic nuclear spin helix and topological superconductivity in C nanotubes
Chen-Hsuan Hsu, Peter Stano, Jelena Klinovaja +1
We investigate the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction arising from the hyperfine coupling between localized nuclear spins and conduction electrons in interacting $^{1…
Phason space analysis and structure modeling of 100 A-scale dodecagonal quasicrystal in Mn-based alloy
Tsutomu Ishimasa, Shuhei Iwami, Norihito Sakaguchi +2
The dodecagonal quasicrystal classified into the five-dimensional space group P126/mmc, recently discovered in a Mn-Cr-Ni-Si alloy, has been analyzed using atomic-resolution spheri…
Gaplessness and the Coulomb anomaly in the strongly disordered films of Molybdenum Carbide
P. Kulkarni, P. Szabo, M. Zemlicka +1
Gaplessness was observed in the disordered films of MoC on approaching to the superconductor to insulator transition by reducing the film thickness. The gaplessness is attributed t…
Electronic magnetization of a quantum point contact measured by nuclear magnetic resonance
Minoru Kawamura, Keiji Ono, Peter Stano +2
We report an electronic magnetization measurement of a quantum point contact (QPC) based on nuclear magnetic resonance (NMR) spectroscopy. We find that NMR signals can be detected…
Microscopic dynamical description of proton-induced fission with the Constrained Molecular Dynamics (CoMD) Model
N. Vonta, G. A. Souliotis, M. Veselsky +1
The microscopic description of nuclear fission still remains a topic of intense basic research. Un- derstanding nuclear fission, apart from a theoretical point of view, is of pract…
Generalized Hofmann quantum process fidelity bounds for quantum filters
