A few remarks on hyperstatistics and some applications
Lucas Squillante, Samuel M. Soares, Guilherme Lepski +1
In a recent paper [arXiv:2604.24783 (2026)], we have proposed a general approach to treat systems with inherent non-Boltzmann-Gibbsian behaviour. Given the extremely high accuracy…
Hyperstatistics
Lucas Squillante, Samuel M. Soares, Constantino Tsallis +1
We propose a general approach, named by us hyperstatistics, to treat complex systems, in which Boltzmann-Gibbs statistics breaks down in domains of the system. Hyperstatistics pres…
Universal and non-universal facets of quantum critical phenomena unveiled along the Schmidt decomposition theorem
Samuel M. Soares, Lucas Squillante, Henrique S. Lima +2
Critical phenomena have been extensively investigated both theoretically and experimentally in many fields, such as condensed matter physics, biology, e.g., brain criticality, and…
Magnetostriction as the origin of the magnetodielectric effect in La2CoMnO6
M. Boldrin, A. Bagri, D. Barlettani +12
The La2CoMnO6 (LCMO) perovskite has received a lot of attention due to its near room temperature magnetodielectric effect. Despite the recent efforts, the mechanism ruling the corr…
Impact of Broken Inversion Symmetry on Molecular States in multi-Weyl fermions
W. C. Silva, J. E. Sanches, D. S. Rojo +6
We study inversion-symmetry (IS) breaking in impurity dimers coupled to topological multi-Weyl systems in the low-energy dispersion domain. In the IS-preserved multi-Weyl semimetal…
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 distin…
