Mecânica quântica no espaço de fase não-comutativo e aplicações em termodinâmica
(Universidade Federal de São Carlos, 2016-08-26)
In this work we study theoretical aspects arising from the fact of considering a
quantum theory with general relations of noncommutativity. Through the quantum
mechanics in phase-space formalism in the Wigner-Weyl ...
Transmissão de emaranhamento através de cadeias de spins
(Universidade Federal de São Carlos, 2018-04-25)
In this thesis we studied the transmission of entangled states in unmodulated spin chains using a slight modification in the XY isotropic model (XX model) that describes a one-dimensional spin-1/2 chain. We have shown that ...
Emaranhamento intrínseco em sistemas tipo-Dirac
(Universidade Federal de São Carlos, 2018-03-06)
Dirac equation is supported by a $SU(2) \otimes SU(2)$ group structure, such that its solutions describe two discrete degrees of freedom, intrinsic parity and spin, which in general are entangled. In this work we will ...
