Correlated Low-Energy Model of Monolayer 1H-NbS: A cRPA+DMFT Study
Karollaine C. Leite, Jorge L. B. de Faria, Luiz Antonio Ribeiro Junior +3
Monolayer hosts a well-separated metallic band of predominant Nb- character, providing an ideal platform to probe electronic correlatio…
Quantum Spin-5/2 Blume-Capel Model in a Random Transverse-Crystalline Field Anisotropy
Claudio M. Salgado, Karollaine C. Leite, Thiago M. Tunes +3
In this work, we investigate the thermodynamic properties of the quantum Blume-Capel model with spin \( S = 5/2 \) in the presence of transverse and random crystalline fields. The…
Probing confined vortices with a superconducting nanobridge
Marek Foltyn, Konrad Norowski, Michał J. Wyszyński +3
We realize a superconducting nanodevice in which vortex traps in the form of an aluminum square are integrated with a Dayem nanobridge. We perform field-cooling of the traps arrivi…
Random-anisotropy mixed-spin Ising on a triangular lattice
E. S. de Santana, A. S. de Arruda, M. Godoy
We have studied the mixed spin-1/2 and 1 Ising ferrimagnetic system with a random anisotropy on a triangular lattice with three interpenetrating sublattices , , and . The…
Critical behavior of the spin-3/2 Blume Capel quantum model with two random transverse single-ion anisotropies
I. J. Souza, M. Godoy, A. S. de Arruda +1
Using the approach based on the Bogoliubov inequality for free energy, we have studied the magnetic properties of the spin-3/2 Blume-Capel quantum model in the presence of the rand…
Phase Diagram of the mixed spin-2 and spin-5/2 Ising system with two different single-ion anisotropies
J. S. da Cruz Filho, M. Godoy, A. S. de Arruda
In this paper we present a study of the effects of two different single-ion anisotropies in the phase diagram and in the compensation temperature of the mixed spin-2 and spin-5/2 I…
Monte Carlo simulations in a disordered binary Ising model
D. S. Cambuí, A. S. de Arruda, M. Godoy
In this work we study a disordered binary Ising model on the square lattice. The model system consists of two different particles with spin-1/2 and spin-1, which are randomly distr…
Heisenberg model in a random field: phase diagram and tricritical behavior
Douglas F. de Albuquerque, A. S. de Arruda
By using the differential operator technique and the effective field theory scheme we study the tricritical behavior of Heisenberg classical model of spin-1/2 in a random field. Th…
