Learning spectral density functions in open quantum systems
Felipe Peleteiro, João Victor Shiguetsugo Kawanami Lima, Pedro Marcelo Prado +2
Spectral density functions quantify how environmental modes couple to quantum systems and govern their open dynamics. Inferring such frequency-dependent functions from time-domain…

Kappa Entropy and its Thermodynamic Connection
J. A. S. Lima, M. H. Benetti
Adopting a bottom-up perspective, we propose a novel two-parametric nonadditive entropy, , associated with a Kappa-type power-law velocity distribution, …

Unified Description of Kappa-type velocity distributions
J. A. S. Lima, M. H. Benetti
An extension of Maxwell's original prescription for an ideal gas is adopted to derive a broad class of Kappa-type velocity distributions, encompassing both fat and short-tailed for…
