Thermodynamic Analogy for Structural Phase Transitions
Pavel Cejnar, Stefan Heinze, Jan Dobes
We investigate the relationship between ground-state (zero-temperature) quantum phase transitions in systems with variable Hamiltonian parameters and classical (temperature-driven)…
On Probabilities of E2 Transitions between Positive-Parity States in ^160Dy Nucleus
J. Adam, V. P. Garistov, M. Honusek +4
Reduced probabilities B(E2) of γtransitions between states of positive parity in the ^160Dy nucleus are calculated within the framework of the interacting boson model (IBM-1). The…
Properties of Excited States in the ^{160}Dy Nucleus
J. Adam, V. P. Garistov, M. Honusek +4
Positive-parity levels and 16 rotational bands are theoretically analyzed on the basis of phenomenological models of the atomic nucleus with the use of new experimental data on exc…
Thermodynamic analogy for quantum phase transitions at zero temperature
Pavel Cejnar, Stefan Heinze, Jan Dobes
We propose a relationship between thermodynamic phase transitions and ground-state quantum phase transitions in systems with variable Hamiltonian parameters. It is based on a link…
Boson Realization of the SU(4) Model of High-Temperature Superconductivity
J. Dobes
The SU(4) algebraic model of high-temperature superconductivity is studied employing the boson mapping techniques. The bosonization of the model enables us to get exact numerical s…
Boson mappings and four-particle correlations in algebraic neutron-proton pairing models
J. Dobes, S. Pittel
Neutron-proton pairing correlations are studied within the context of two solvable models, one based on the algebra SO(5) and the other on the algebra SO(8). Boson-mapping techniqu…
