Quantum theory of spin waves in finite chiral spin chains
(American Physical Society, 2014)
We calculate the effect of spin waves on the properties of finite-size spin chains with a chiral spin ground
state observed on biatomic Fe chains deposited on iridium(001). The system is described with a Heisenberg
model ...
Inducing critical phenomena in spin chains through sparse alternating fields
(American Physical Society, 2019-01-09)
We analyze the phase diagram of the exact ground state (GS) of spin-s chains with ferromagnetic XXZ couplings under n-alternating field configurations, i.e., sparse alternating fields having nodes at n − 1 contiguous sites. ...

Estudo do modelo XY por Monte Carlo
(Universidade Federal de Minas GeraisUFMG, 2014-09-09)
Phase transitions in spins systems offers perspectives in understanding low tempera- ture critical behavior of matter. In this work we applied the Stochastic Series Expansion method to study the critical properties of ...
A Spin / Promela Application for Model checking UML Sequence Diagrams
(2018)
UML sequence diagrams usually represent the behavior of systems execution. Automated verification of UML sequence diagrams’ correctness is necessary because they can model critical algorithmic behaviors of information ...

Factorization and Criticality in Finite XXZ Systems of Arbitrary Spin
(American Physical Society, 2017-12)
We analyze ground state (GS) factorization in general arrays of spins si with XXZ couplings immersed in nonuniform fields. It is shown that an exceptionally degenerate set of completely separable symmetry-breaking GSs can ...
