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…

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…

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…
