# Nonlinear response of solids within the GW plus Bethe-Salpeter approximation

# Nonlinear response of solids within the GW plus Bethe-Salpeter approximation

My new talk for the GDR-Corr is available online. In this talk I will present our new (probably not so new now) approach to calculate non-linear response in extended systems within the GW plus Bethe-Salpeter equation. I put different references in the presentation that can be interesting for the reader.

# How many theoreticians do you need to make a good paper? (probably no more than three)

# How many theoreticians do you need to make a good paper? (probably no more than three)

I just attended a seminar on network theory. The speaker[1] presented some interesting results on the reconstruction of communities in static or temporal networks. The talk was clear and the results well presented, but the thing that impressed me more were the references. The results, he had shown, were produced from 2012 to 2015 and… Read More

# How to plot the Dipole Moment calculated by NWCHEM with XCrysDen

# How to plot the Dipole Moment calculated by NWCHEM with XCrysDen

Dipole moment of molecules is an interesting physical quantity that can be directly measured in experiments and easily calculated by means of Density Functional Theory. Moreover the size of dipole moment is related to many other properties as for instance light emission in polar liquid, packing of molecules in solid phase. With NWChem it can… Read More
