A misfit parameter is used to characterize the degree of frustration of ordered and disordered systems. It measures the increase of the ground-state energy due to frustration in comparison with that of a relevant reference state. The misfit parameter is calculated for various spin-glass models. It allows one to compare these models with each other. The extension of this concept to other combina...
The frustratometer is an energy landscape theory-inspired algorithm that aims at quantifying the location of frustration manifested in protein molecules. Frustration is a useful concept for gaining insight to the proteins biological behavior by analyzing how the energy is distributed in protein structures and how mutations or conformational changes shift the energetics. Sites of high local frus...
High sensitivity measurements of the dielectric constant of solid oxygen are reported for 4 T 54 K. The results show unexpectedly large hysteresis effects for the temperature dependence of the dielectric constant in the and phases of oxygen on thermal cycling below 44 K. The behavior is compared to that observed for solid N2-Ar mixtures where the geometrical frustration of the molecular orienta...
