Symmetry Algebras of Stringy Cosets
Dushyant Kumar, Menika Sharma
We find the symmetry algebras of cosets which are generalizations of the minimal-model cosets, of the specific form . We study…
Multicomplex solitons
Julia Cen, Andreas Fring
We discuss integrable extensions of real nonlinear wave equations with multi-soliton solutions, to their bicomplex, quaternionic, coquaternionic and octonionic versions. In particu…
Time-dependent Darboux (supersymmetric) transformations for non-Hermitian quantum systems
Julia Cen, Andreas Fring, Thomas Frith
We propose time-dependent Darboux (supersymmetric) transformations that provide a scheme for the calculation of explicitly time-dependent solvable non-Hermitian partner Hamiltonian…
Model confidence sets and forecast combination: An application to age-specific mortality
Han Lin Shang, Steven Haberman
Model averaging combines forecasts obtained from a range of models, and it often produces more accurate forecasts than a forecast from a single model. The crucial part of forecast…
Generating Magnetic Resonance Spectroscopy Imaging Data of Brain Tumours from Linear, Non-Linear and Deep Learning Models
Nathan J Olliverre, Guang Yang, Gregory Slabaugh +2
Magnetic Resonance Spectroscopy (MRS) provides valuable information to help with the identification and understanding of brain tumors, yet MRS is not a widely available medical ima…
Evolution of urban scaling: evidence from Brazil
Joao Meirelles, Camilo Rodrigues Neto, Fernando Fagundes Ferreira +2
During the last years, the new science of municipalities has been established as a fertile quantitative approach to systematically understand the urban phenomena. One of its main p…
Quasi-exactly solvable quantum systems with explicitly time-dependent Hamiltonians
Andreas Fring, Thomas Frith
For a large class of time-dependent non-Hermitain Hamiltonians expressed in terms linear and bilinear combinations of the generators for an Euclidean Lie-algebra respecting differe…
Universal trees grow inside separating automata: Quasi-polynomial lower bounds for parity games
Wojciech Czerwiński, Laure Daviaud, Nathanaël Fijalkow +3
Several distinct techniques have been proposed to design quasi-polynomial algorithms for solving parity games since the breakthrough result of Calude, Jain, Khoussainov, Li, and St…
The low-energy limit of AdS/CFT and its TBA
Diego Bombardelli, Bogdan Stefański, Alessandro Torrielli
We investigate low-energy string excitations in AdSST. When the worldsheet is decompactified, the theory has gapless modes whose spectrum at low energies is…
True Contextuality Beats Direct Influences in Human Decision Making
Irina Basieva, Víctor H. Cervantes, Ehtibar N. Dzhafarov +1
In quantum physics there are well-known situations when measurements of the same property in different contexts (under different conditions) have the same probability distribution,…
Entangling three qubits without ever touching
Pawel Blasiak, Marcin Markiewicz
All identical particles are inherently correlated from the outset, regardless of how far apart their creation took place. In this paper, this fact is used for extraction of entangl…
Entanglement Content of Quantum Particle Excitations I. Free Field Theory
Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1
We evaluate the entanglement entropy of a single connected region in excited states of one-dimensional massive free theories with finite numbers of particles, in the limit of large…
Entanglement Content of Quasi-Particle Excitations
Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1
We investigate the quantum entanglement content of quasi-particle excitations in extended many-body systems. We show that such excitations give an additive contribution to the bi-p…
Asymptotic and scattering behaviour for degenerate multi-solitons in the Hirota equation
Julia Cen, Andreas Fring
We construct all higher order conserved charges from a general two-dimensional zero curvature condition using a Gardner transformation. Employing two of those charges in the defini…
A Score-Driven Conditional Correlation Model for Noisy and Asynchronous Data: an Application to High-Frequency Covariance Dynamics
Giuseppe Buccheri, Giacomo Bormetti, Fulvio Corsi +1
The analysis of the intraday dynamics of correlations among high-frequency returns is challenging due to the presence of asynchronous trading and market microstructure noise. Both…
The State of the Art in Integrating Machine Learning into Visual Analytics
A. Endert, W. Ribarsky, C. Turkay +4
Visual analytics systems combine machine learning or other analytic techniques with interactive data visualization to promote sensemaking and analytical reasoning. It is through su…
LeClair-Mussardo series for two-point functions in Integrable QFT
B. Pozsgay, I. M. Szécsényi
We develop a well-defined spectral representation for two-point functions in relativistic Integrable QFT in finite density situations, valid for space-like separations. The resulti…
