Dissipative dynamics of topological defects in frustrated Heisenberg spin systems
V. Juricic, L. Benfatto, A. O. Caldeira +1
We study the dynamics of topological defects of a frustrated spin system displaying spiral order. As a starting point we consider the SO(3) nonlinear sigma model to describe long-w…

Dynamics of topological defects in a spiral: a scenario for the spin-glass phase of cuprates
V. Juricic, L. Benfatto, A. O. Caldeira +1
We propose that the dissipative dynamics of topological defects in a spiral state is responsible for the transport properties in the spin-glass phase of cuprates. Using the collect…

Effect of orbital currents on the restricted optical sum rule
L. Benfatto, S. G. Sharapov, H. Beck
We derive the restricted optical-conductivity sum rule for a model with circulating orbital currents. It is shown that an unusual coupling of the vector potential to the interactio…
