Intermediate temperature dynamics of one-dimensional Heisenberg antiferromagnets
Chiranjeeb Buragohain, Subir Sachdev
We present a general theory for the intermediate temperature (T) properties of Heisenberg antiferromagnets of spin-S ions on p-leg ladders, valid for 2Sp even or odd. Following an…

High temperature relaxational dynamics in low-dimensional quantum field theories
Subir Sachdev
This paper presents a unified perspective on the results of two recent works (C. Buragohain and S. Sachdev cond-mat/9811083 and S. Sachdev cond-mat/9810399) along with additional b…

Universal relaxational dynamics near two-dimensional quantum-critical points
Subir Sachdev
We describe the nonzero temperature (T), low frequency (ω) dynamics of the order parameter near quantum critical points in two spatial dimensions (d), with a special focus on the r…
