变形玻色子和费米子的热统计

Thermostatistics of deformed bosons and fermions

A. Lavagno, P. Narayana Swamy

摘要:

基于q-变形振子代数,研究了平均占有数的性质及其与中间统计量的类比,得到了一个无穷连分式的表达式,从而澄清了逐次逼近.在这个框架下,我们研究了q-变形玻色子和费米子的热统计,并表明热力学可以建立在q-演算的形式上。如果用适当的杰克逊导数和q积分代替普通导数,热力学的整个结构就得以保持。在此基础上,我们导出了最重要的热力学函数,并在热力学极限下研究了q玻色子和q费米子理想气体。

英文摘要:

Based on the q-deformed oscillator algebra, we study the behavior of the mean occupation number and its analogies with intermediate statistics and we obtain an expression in terms of an infinite continued fraction, thus clarifying successive approximations. In this framework, we study the thermostatistics of q-deformed bosons and fermions and show that thermodynamics can be built on the formalism of q-calculus. The entire structure of thermodynamics is preserved if ordinary derivatives are replaced by the use of an appropriate Jackson derivative and q-integral. Moreover, we derive the most important thermodynamic functions and we study the q-boson and q-fermion ideal gas in the thermodynamic limit.
