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…

Ward identity and optical-conductivity sum rule in the d-density wave state
L. Benfatto, S. Sharapov, N. Andrenacci +1
We consider the role of the Ward identity in dealing with the transport properties of an interacting system forming a d-wave modulated charge-density wave or staggered flux phase.…
