Density matrix for a consistent non-extensive thermodynamics
Marcelo R. Ubriaco
Starting with the average particle distribution function for bosons and fermions for non-extensive thermodynamics , as proposed in \cite{CMP}, we obtain the corresponding density m…
The role of curvature in quantum statistical mechanics
Marcelo R. Ubriaco
In this manuscript, we calculate the scalar curvature of a two-dimensional thermodynamic space to study the properties of two thermodynamic systems. In particular, we study the sta…
Linear model of tumor growth in a changing environment
José F. Nieves, Marcelo R. Ubriaco
We propose a model for describing the growth on an untreated tumor, which is characterized in a simple way by a minimal number of parameters with a well-defined physical interpreta…
Anyonic behavior of quantum group fermionic and bosonic systems
Marcelo R. Ubriaco
We discuss the role that quantum group symmetries, in particular , play in a thermodynamic system at high temperatures. We show that the interactions introduced by the qua…
