Biophysical models of specificity.
DNA targeting specificity of RNA-guided Cas9 nucleases (https://crispr.bme.gatech.edu/): Contains experimental data about the specificity. They also have a server based on the data.
A Biophysical Model of CRISPR/Cas9 Activity for Rational Design of Genome Editing and Gene Regulation: This is a simple biophysical model used to predict the specificity of the sgRNA based on the sequence. They split the process in 3 steps and add the free energy change of each process to calculate a binding energy.
High-fidelity CRISPR–Cas9 nucleases with no detectable genome-wide off-target effects : Mutations on residues that bind to the phosphate backbone of the DNA can improve the specificity.

QM:MM Simulations
Gamess+Tinker http://cfm.ehu.es/ricardo/master/intranet_ESCMAN/WinGAMESS/manuals/simomm.pdf (advantages: free, disadvantages: might not run well )
Gaussian+Gromacs http://www.gromacs.org/Downloads/Installation_Instructions/compiling_QMMM (advantages: will work well, Scuseria will likely help; disadvantages: will likely be limited to Rice U comp. resources.)
