The method to be used is molecular dynamics (MD) with periodic boundary conditions using CP2K. The aim is to explore the method, calculate the radial distribution function $g(r)$$U(x)=4\epsilon \left [\left ( \frac{\sigma }{r_{ij}} \right )^{12}- \left ( \frac{\sigma }{r_{ij}} \right )^{6} \right ]$$\epsilon$$\sigma$$r_{ij}$$r_{ij}$$\sigma$$g(r)$$\rho$$\epsilo… text/html 2021-05-19T14:30:29+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.cp2k.org/exercises:2021_uzh_acpc2:ex02?rev=1621434629&do=diff Molecular Solution Water Water molecular models are computational techniques that have been developed in order to help discover the structure of water. In this section, you will be asked to calculate some physical properties based on classical molecular dynamics simulation. The TIP3/Fw model will be used in the simulations. $g(r)$$r$$g(r)$$g_{O-O}(r)$\begin{equation} A(\omega)\propto{\int\langle{\dot{\mu}}({\tau}){\dot{\mu}}(t+{\tau})\rangle_{\tau}e^{-i{\omega}t}d{t}} \ . \label{eq:auto} \end{… text/html 2021-05-21T10:13:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.cp2k.org/exercises:2021_uzh_acpc2:ex03?rev=1621592034&do=diff Nudged elastic band and free energy calculations In this exercise we will study the $S_N2$ nucleophilic substitution reaction: $$ \text{Cl}^- + \text{CH}_3\text{Cl} \longleftrightarrow \text{Cl}\text{CH}_3 + \text{Cl}^-. $$ For the energy and force evaluation, we will use the Parameterization Method 6 (PM6), which is a relatively inexpensive semiempirical model for electronic structure evaluation.
