A condition for the uniqueness of Gibbs states in one-dimensional models
(Elsevier BV * North-Holland, 1998)
Uniqueness of limit Gibbs states of one dimensional models with a unique "stable" ground state is established at low temperatures. © 1998 Elsevier Science B.V. All rights reserved.
Ground states of one-dimensional long-range ferromagnetic ising model with external field
(World Scientific Publishing, 2012)
A zero-temperature phase-diagram of the one-dimensional ferromagnetic Ising model is investigated. It is shown that at zero temperature spins of any compact collection of lattice points with identically oriented external ...
Triplets of closely embedded Dirichlet type spaces on the unit polydisc
(Birkhaeuser Science, 2013)
We propose a general concept of triplet of Hilbert spaces with closed embeddings, instead of continuous ones, and we show how rather general weighted L2 spaces yield this kind of generalized triplets of Hilbert spaces for ...
Absence of phase transitions in one-dimensional antiferromagnetic models with long-range interactions
(Kluwer Academic Publishers-Plenum PublishersSpringer New York LLC, 1993)
The absence of phase transitions in a one-dimensional model with long-range antiferromagnetic potential is established at low temperatures when the ground states have a rational density. A description of the set of all ...
Phase transition in one dimensional model with unique ground state
(Elsevier BV * North-Holland, 1996)
A one - dimensional model having a unique ground state and admitting a phase transition is constructed.
Triplets of closely embedded Hilbert spaces
We obtain a general concept of triplet of Hilbert spaces with closed (unbounded) embeddings instead of continuous (bounded) ones. We provide a model and an abstract theorem as well for a triplet of closely embedded Hilbert ...
