We consider pairing of itinerant fermions in a metal near quantum-critical point (QCP) towards some form particle-hole order (nematic, spin-density-wave, charge-density-wave, etc). At QCP, the dominant interaction between comes from exchanging massless fluctuations critical parameter. low energies, this physics can be described by an effective model with dynamical electron-electron $V(\Omega_m)...

The accuracy and reliability of the density functional theory (DFT)-D approach to account for dispersion effects in first-principles studies of water-metal interfaces has been addressed by studying several water-metal systems. In addition to performing periodic DFT calculations for semi-infinite substrates using the popular PBE and RPBE functionals, the water dimer and water-metal atom systems ...
