Topology-Controlled Phonon Dielectric Response Beyond Density Scaling in Metal-Organic Frameworks
Debayan Mondal, Jiahao Ye, Lorenzo Donà +1
Effective-medium theory treats material porosity as passive dilution. Using ab initio density functional theory and high-resolution synchrotron terahertz (THz) spectroscopy on isoc…

Nonlinear optical response and spontaneous polarization in layer-stacked gallenene using second harmonic generation
Muhammad Yunusa, Andrew K. Schulz, Tim Parker +12
Gallenene is a promising low-dimensional material with a structure down to the thickness of a single atom, similar to graphene. However, van der Waals stacking of two-dimensional (…
