The influence of boundary conditions on the emergence of non-compact degrees of freedom in the scaling limit of integrable lattice models

Gehrmann, Sascha (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2024)

One-dimensional critical integrable lattice models with a finite-dimensional degree of freedom attached to each lattice site can exhibit the remarkable phenomenon of the emergence of continuous degrees of freedom in the ...
Integrable boundary conditions for staggered vertex models

Frahm, Holger; Gehrmann, Sascha (Bristol : IOP Publ., 2023)

Yang-Baxter integrable vertex models with a generic Z 2 -staggering can be expressed in terms of composite R -matrices given in terms of the elementary R-matrices. Similarly, integrable open boundary conditions can be ...
Optimal Connection of Heat Pump and Solar Buffer Storage under Different Boundary Conditions

Glembin, Jens; Büttner, Christoph; Steinweg, Jan; Rockendorf, Gunter (London : Elsevier Ltd., 2016)

The paper presents the results of a simulation study, in which the connection of heat pumps and buffer storage tanks has been investigated. The simulations are carried out for a new type of a solar thermal combi system ...
