A First Course in String Theory
.
Write a double sum that represents the statistical mechanics partition function for the quantum mechanical system considered in Section 2.10. Note that
factors as
.
~~~
Eq. (2.118):
Eq. (2.119):
.
[guess]
Index but not negative integers because, for example,
and
give physically identical states
and
.
The two wave functions give the same probability density distribution, if .
However, that is not the case for
.
So should have also negative integers as possible values:
.
[guess]
