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

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

Exact solution of a two-parameter extended Bariev model
Nuclear Physics BAn exactly solvable strongly correlated electron model with two independent parameters is constructed in the frame of the quantum inverse scattering method, which can be seen as a generalization of the Bariev model. Through the Bethe ansatz method, a set

On the solutions of the Zn-Belavin model with arbitrary number of sites
Nuclear Physics B, 2017 The periodic Zn-Belavin model on a lattice with an arbitrary number of sites N is studied via the off-diagonal Bethe Ansatz method (ODBA). The eigenvalues of the corresponding transfer matrix are given in terms of an unified inhomogeneous T−Q relation ...

Advanced Functional Materials, Volume 34, Issue 19, May 10, 2024.Ambipolar electrolyte‐gated transistors based on reduced graphene oxide (rGO‐EGTs) are ultra‐sensitive and highly specific immunosensors. The physics and chemistry ruling the device operation are still not fully unraveled. This work aims to elucidate the nature of the observed sensitivity, by proposing a physical–chemical model that quantitatively ...

Y-system for γ-deformed ABJM theory
Journal 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 ...

Boundary current fluctuations for the half‐space ASEP and six‐vertex model
Proceedings of the London Mathematical Society, Volume 128, Issue 2, February 2024.Abstract We study fluctuations of the current at the boundary for the half‐space asymmetric simple exclusion process (ASEP) and the height function of the half‐space six‐vertex model at the boundary at large times. We establish a phase transition depending on the effective density of particles at the boundary, with Gaussian symplectic ensemble (GSE ...

On Bethe vectors in gl3 $$ \mathfrak{g}{\mathfrak{l}}_3 $$-invariant integrable models
Journal of High Energy Physics, 2018 We consider quantum integrable models solvable by the nested algebraic Bethe ansatz and possessing gl3 $$ \mathfrak{g}{\mathfrak{l}}_3 $$-invariant R-matrix.

Finding the Dynamics of an Integrable Quantum Many‐Body System via Machine Learning
Advanced Physics Research, Volume 3, Issue 1, January 2024.Machine‐learning methods are used to find nonperturbative dynamics of the Gaudin magnet (central‐spin model). The Gaudin magnet has important applications in qubit dynamics/decoherence and in nonequilibrium superconductivity. Integrable models like the Gaudin magnet have many conserved quantities and their dynamics may therefore admit an efficient ...

Massless AdS 2 scattering and Bethe ansatz [PDF]
Journal of High Energy Physics, 2017 We first analyse the integrable scattering theory describing the massless excitations of $AdS_2 \times S^2 \times T^6$ superstrings in the relativistic limit. The matrix part of the S-matrix is obtained in the BMN limit from the conjectured exact expression, and compared with known S-matrices with N=1 supersymmetry.
