The Grüneisen parameter applied to critical phenomena and experimental investigations of correlated phenomena in molecular conductors
Lucas Squillante
In this Ph.D. Thesis, a systematic review is performed on the derivation and generalization of the Grüneisen parameter followed by its unprecedented applications to several distinc…
Higgs-like stiffness and fractons on the verge of phase transitions
Lucas Squillante, Antonio C. Seridonio, Roberto E. Lagos-Monaco +1
In condensed matter Physics, massive longitudinal Higgs modes emerge from fluctuations of the order parameter. A few years ago, the Higgs mode was \emph{caught} experimentally in t…
Unveiling the Physics of the Mutual Interactions in Paramagnets
Lucas Squillante, Isys F. Mello, Gabriel O. Gomes +4
In real paramagnets, there is always a subtle many-body contribution to the system's energy, which can be regarded as a small effective local magnetic field . Usually, it…
Griffiths-like phase close to the Mott transition
Isys F. Mello, Lucas Squillante, Gabriel O. Gomes +2
We explore the coexistence region in the vicinity of the Mott critical end point employing a compressible cell spin- Ising-like model. We analyze the case for the spin-liquid…
The Magnetic Grüneisen Parameter for Model Systems
Gabriel Gomes, Lucas Squillante, A. C. Seridonio +3
The magneto-caloric effect (MCE), which is the refrigeration based on the variation of the magnetic entropy, is of great interest in both technological applications and fundamental…
Probing the Ionic Dielectric Constant Contribution in the Ferroelectric Phase of the Fabre-Salts
Mariano de Souza, Lucas Squillante, Cesar Sônego +3
In strongly correlated organic materials it has been pointed out that charge-ordering could also achieve electronic ferroelectricity at the same critical temperature . A pr…
