Beyond Electrons: Correlation and Self‐Energy in Multicomponent Density Functional Theory

open access: yesChemPhysChem, Volume 25, Issue 13, July 2, 2024.
Developing robust methods to describe the behavior of fermions embedded into an electronic system is vital to computationally tackle these complicated quantum systems. Introducing various new approaches, including a common auxiliary subspace multicomponent resolution‐of‐the‐identity approach, this work provides powerful techniques to extract ...

Spin-$s$ rational $Q$-system

open access: yesSciPost Physics
Bethe Ansatz equations for spin-s Heisenberg spin chain with s≥1 are significantly more difficult to analyze than the spin-$\tfrac{1}{2}$ case, due to the presence of repeated roots. As a result, it is challenging to derive extra conditions for the Bethe

Heisenberg XXX Model with General Boundaries: Eigenvectors from Algebraic Bethe Ansatz

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
We propose a generalization of the algebraic Bethe ansatz to obtain the eigenvectors of the Heisenberg spin chain with general boundaries associated to the eigenvalues and the Bethe equations found recently by Cao et al.

Exact solution of the XXZ Gaudin model with generic open boundaries

open access: yes, 2004
The XXZ Gaudin model with {\it generic} integerable boundaries specified by generic {\it non-diagonal} K-matrices is studied. The commuting families of Gaudin operators are diagonalized by the algebraic Bethe ansatz method.

Classical and quantum theory of fluctuations for many‐particle systems out of equilibrium

open access: yesContributions to Plasma Physics, Volume 64, Issue 5, June 2024.
Abstract Correlated classical and quantum many‐particle systems out of equilibrium are of high interest in many fields, including dense plasmas, correlated solids, and ultracold atoms. Accurate theoretical description of these systems is challenging both, conceptionally and with respect to computational resources.

Y-system for γ-deformed ABJM theory

open access: yesJournal of High Energy Physics, 2017
We investigate the integrable aspects of the planar γ-deformed ABJM theory and propose the twisted asymptotic Bethe ansatz equations. A more general method through a twisted generating functional is discussed, based on which, the asymptotic large L ...

Algebraic Bethe Ansatz for the FPL^2 model

open access: yes, 2004
An exact solution of the model of fully packed loops of two colors on a square lattice has recently been proposed by Dei Cont and Nienhuis using the coordinate Bethe Ansatz approach.

Präparierte Emotionen: Formen der Trauer im Umgang mit der Stellerschen Seekuh

open access: yesThe German Quarterly, Volume 97, Issue 3, Page 299-318, Summer 2024.
Abstract Wie werden Emotionen im Kontext des Artenverlusts eingesetzt? In welchem Ausmaß sind sie steuerbar und für welche Zwecke werden sie genutzt? Anhand des Beispiels der Stellerschen Seekuh fragt der Artikel nach Formen der Trauer im Umgang mit der Auslöschung und den Überresten des marinen Säugetiers.
