Thermodynamics of interacting magnetic chain molecules
Alexios P. Polychronakos, Konstantinos Sfetsos
We study magnets composed of molecules with an arbitrary number of magnetically active atoms in a chain configuration interacting with nearest-neighbor couplings. We derive the…
Interacting multicomponent magnets
Alexios P. Polychronakos, Konstantinos Sfetsos
We study magnets composed of molecules with atoms interacting via -invariant two-body interactions. Atoms carry states transforming in generically different irreducible repr…
Nonabelian ferromagnets with three-body interactions
Alexios P. Polychronakos, Konstantinos Sfetsos
We study the thermodynamics of nonabelian ferromagnets consisting of atoms in the fundamental representation of and interacting with two-body and three-body interactions. U…
Ferromagnets from higher representations
Alexios P. Polychronakos, Konstantinos Sfetsos
We present a general formalism for deriving the thermodynamics of ferromagnets consisting of "atoms" carrying an arbitrary irreducible representation of and coupled through…
Triple critical point and emerging temperature scales in ferromagnetism at large
Alexios P. Polychronakos, Konstantinos Sfetsos
The non-Abelian ferromagnet recently introduced by the authors, consisting of atoms in the fundamental representation of , is studied in the limit where becomes large an…
Phase transitions in the decomposition of representations
Alexios P. Polychronakos, Konstantinos Sfetsos
We study the multiplicity of irreducible representations in the decomposition of fundamentals of weighted by a power of their dimension in the large and large d…
