Quantum decoration transformation for spin models
(Elsevier, 2019)
Factorization and criticality in the anisotropic XY chain via correlations
(Mdpi Ag, 2015-01-01)
In this review, we discuss the zero and finite temperature behavior of various bipartite quantum and total correlation measures, the skew information-based quantum coherence and the local quantum uncertainty in the thermal ...
Towards the solution of an integrable spin chain
(2019-10-03)
Two branches of integrable open quantum-group invariant Dn+1 (2) quantum spin chains are known. For one branch (ϵ = 0), a complete Bethe ansatz solution has been proposed. However, the other branch (ϵ = 1) has so far ...
Rectification and one-way street for the energy current in boundary-driven asymmetric quantum spin chains

Quantum discord and related measures of quantum correlations in finite XY chains
(World Scientific, 2013-05)
We examine the quantum correlations of spin pairs in the ground state of finite XY chains in a transverse field, by evaluating the quantum discord as well as other related entropic measures of quantum correlations. A brief ...
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 ...
Controlled quantum state transfer in XX spin chains at the Quantum Speed Limit
(Elsevier Science, 2021-01)
The Quantum Speed Limit (QSL) can be found in many different situations, in particular in the propagation of information through quantum spin chains. In homogeneous chains it implies that taking information from one extreme ...
