What would most of us do with only three hours of
electricity per day? Yet that is what Dr. Sabiha Al-Jabbar
did when she was working on her PhD in Baghdad. She
had to design her experiments so that she could have
the results she needed before the lights went out.

This PhD thesis examines the thermodynamical properties of spin-1/2 Heisenberg chains which are
coupled to Einstein phonons. One result of this study is that these spin-phonon systems undergo a
phase transition similar to a spin-Peierls transition (cf. Physical Review B 60 (1999) 12125-12133
and Physical Review B 65 (2002) 144438). Another result is that in the undimerized phase the critical
exponent nu depends on both the phonon frequency and the spin-phonon coupling constant. This means
that these spin-phonon systems change the universality class continuously with the spin-phonon
coupling (cf. arXiv: cond-mat/9912150v1).

We accept the statement that �carriers in graphene
are described not by the Schrödinger equation� as a
challenge to show that electrons in graphene can be
described by the Schr�dinger equation.
