Negative Thermal Expansion in Open Perovskites near the Precipice of Structural Stability
(2018)
Negative thermal expansion (NTE) describes the anomalous propensity of materials to shrink when heated. Since its discovery, the NTE effect has been found in a wide variety of materials with an array of magnetic, electronic ...

Termalização e correlações quânticas nos contextos de sistemas quânticos abertos e cadeias de spins
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2013-01-11)
In this thesis, we study the behavior of Quantum Discord in the contexts of open quantum systems and spin chains. Furthermore, we investigate the thermalization process of a spin chain due to interaction with the environment. ...
Scaling laws in the quantum-to-classical transition in chaotic systems
(American Physical Society, 2009-02)
We study the quantum-to-classical transition in a chaotic system surrounded by a diffusive environment. First, we analyze the emergence of classicality when it is monitored by the Renyi entropy, a measure of the entanglement ...
