Superintegrability on sl(2)-coalgebra spaces

open access: yes, 2007
We review a recently introduced set of N-dimensional quasi-maximally superintegrable Hamiltonian systems describing geodesic motions, that can be used to generate "dynamically" a large family of curved spaces. From an algebraic viewpoint, such spaces are

On ergodic operator means in Banach spaces

open access: yes, 2015
We consider a large class of operator means and prove that a number of ergodic theorems, as well as growth estimates known for particular cases, continue to hold in the general context under fairly mild regularity conditions. The methods developed in the

Determination of Boundary Scattering, Intermagnon Scattering, and the Haldane Gap in Heisenberg Chains

open access: yes, 2011
Low-lying magnon dispersion in a S=1 Heisenberg antiferromagnetic (AF) chain is analyzed using the non-Abelian DMRG method. The scattering length $a_{\rm b}$ of the boundary coupling and the inter-magnon scattering length $a$ are determined.

Lattice model for the surface states of a topological insulator with applications to magnetic and exciton instabilities

open access: yes, 2012
A surface of a strong topological insulator (STI) is characterized by an odd number of linearly dispersing gapless electronic surface states. It is well known that such a surface cannot be described by an effective two-dimensional lattice model (without ...

Phase diagram of the isotropic spin-3/2 model on the z=3 Bethe lattice

open access: yes, 2013
We study an SU(2) symmetric spin-3/2 model on the z=3 Bethe lattice using the infinite Time Evolving Block Decimation (iTEBD) method. This model is shown to exhibit a rich phase diagram. We compute the expectation values of several order parameters which

Percepcja Organizacji Jedności Afrykańskiej w świetle zachowanych dokumentów Departamentu V i Departamentu II MSZ PRL z lat 1963–1989

open access: yesPamięć i Sprawiedliwość, 2023
Celem artykułu jest analiza dokumentów dotyczących Organizacji Jedności Afrykańskiej powstałych w Departamencie V i Departamencie II MSZ PRL w latach 1963–1989. Polscy dyplomaci od utworzenia OJA monitorowali działalność tej organizacji w kontekście przemian zachodzących na kontynencie afrykańskim.
