Anisotropic models in LQC with GBP polymerisation
D. A. Cook, A. Olimpieri, I. P. R. Baranov +2
Polymer models are effective in describing quantum gravity effects around the initial singularity, leading to its replacement by bouncing surfaces on which the curvature and densit…
Interactions of the deuteron with a hadronic medium
L. M. Abreu, R. Higa, R. O. Magalhães +1
We investigate the interactions of the deuteron with light mesons during the hadronic phase in heavy-ion collisions. We treat the deuteron as a weakly bound state and employ the qu…
Production of the state via the decay
Luciano M. Abreu
In this work the production of the state is estimated via the reaction through triangle mechanisms described by the sequence $B^0 \to D_s^{(*…
Dark Degeneracy in DESI DR2: Interacting or Evolving Dark Energy?
Vitor Petri, Valerio Marra, Rodrigo von Marttens
The standard CDM model, despite its success, is challenged by persistent observational tensions in the Hubble constant () and the matter clustering amplitude (), motiv…
Eigenvalue Distribution of Empirical Correlation Matrices for Multiscale Complex Systems and Application to Financial Data
Luan M. T. de Moraes, Antônio M. S. Macêdo, Giovani L. Vasconcelos +1
We introduce a method for describing eigenvalue distributions of correlation matrices from multidimensional time series. Using our newly developed matrix H theory, we improve the d…
Entropy production and statistical relaxation of dipolar bosons and fermions in interaction quench dynamics
Barnali Chakrabarti, N D Chavda, F. V. Prudente
We study the out-of-equilibrium dynamics of dipolar bosons and fermions after a sudden change in the interaction strength from zero to a finite repulsive value. We simulate the int…
