Electronic structure studies of diradicals derived from Closo-Carboranes
(Springer, 2013-03)
Electronic structure computations have been performed on diradical systems composed of two carborane radicals CB11H12 connected through acetylene, ethylene and ethane bridge units, leading, respectively, to a linear and ...
Magnetization plateaus and Luttinger liquid behavior in XXZ chains with superlattice structure
(American Physical SocCollege PkEUA, 2002)
Generation of chiral solitons in antiferromagnetic chains by a quantum quench
(American Physical Society, 2013-11)
We analyze the time evolution of a magnetic excitation in a spin-12 antiferromagnetic Heisenberg chain after a quantum quench. By a proper modulation of the magnetic exchange coupling, we prepare a static soliton of total ...
Effect of the canting of local anisotropy axes on ground-state properties of a ferrimagnetic chain with regularly alternating Ising and Heisenberg spins
(Polish Academy of Sciences, Institute of Physics, 2019)
Finite-size calculation of anisotropic antiferromagnetic chains at Nonzero field

Transferência de estado quântico em cadeias de spin
(Universidade Federal do Rio Grande do NorteBrasilUFRNBacharelado em Física, 2017-10-07)
Quantum communication consists in transferring quantum states from one place to another. One of its most well known applications is quantum key distribution, in which a random secret key with security guaranteed by the ...
Inhomogeneous superconducting phases in the frustrated Kondo-Heisenberg chain
(American Physical Society, 2013-06)
We use bosonization and renormalization group methods to determine the ground-state phase diagram of a one-dimensional frustrated Kondo-Heisenberg system consisting of a one-dimensional spin- 1/2 Luttinger liquid coupled ...
Quantum Correlations And Coherence In Spin-1 Heisenberg Chains
