Optimal excitation of 23Na nuclear spins in the presence of residual quadrupolar coupling and quadrupolar relaxation
Optimal control theory is applied for designing pulse sequences to optimally excite a spin-3/2 system with residual quadrupolar coupling in the presence of quadrupolar relaxation. A homogeneous form o...

Coadsorption of CO and NO on the Cu2O(111) surface: A periodic density functional theory study
Coadsorption of carbon monoxide (CO) and nitric oxide (NO) on the Cu2O(111) surface was studied using periodic density functional theory calculations. It is interesting to find that CO+NO on Cu2O(111)...

The hydrodynamical equations and the notion of a frequency dependent complex specific heat near the critical point of binary liquids are used to obtain an expression for the low-frequency bulk viscosity. In this way the interrelations between different theoretical models, treating the critical sound attenuation from either a specific heat or a bulk viscosity approach, are made evident. The general structure of the bulk viscosity relation agrees with that of Onuki [Phys. Rev. E 55, 403 (1997)] but a universal number emerges only if a normalization to the critical point value is done.
