Density matrix for a consistent non-extensive thermodynamics

Marcelo R. Ubriaco

摘要:

从非广延热力学中玻色子和费米子的平均粒子分布函数出发,得到了相应的密度矩阵算符和哈密顿量。特别是,对于玻色子的情况下,相应的运营商满足变形玻色子代数和哈密顿量涉及相互作用项的权力$a^{\dagger}_ja_j$标准创建和湮灭运营商。对于非规范化的密度矩阵,我们得到一个非线性方程,导致一个两个参数的解决方案有关的反常扩散现象。

英文摘要:

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 matrix operators and hamiltonians. In particular, for the bosonic case the corresponding operators satisfy a deformed bosonic algebra and the hamiltonian involves interacting terms in powers of $a^{\dagger}_ja_j$ standard creation and annihilation operators. For the unnormalized density matrix we obtain a nonlinear equation that leads to a two-parameter solution relevant to anomalous diffusion phenomena.
