Universal Magnetic Properties of Frustrated Quantum Antiferromagnets in Two Dimensions
A. V. Chubukov, T. Senthil, S. Sachdev
We present a theory of frustrated, two-dimensional, quantum antiferromagnets in the vicinity of a quantum transition from a non-collinear, magnetically-ordered ground state to a qu…
Universal Behavior of the Spin-Echo Decay Rate in La_2CuO_4
A. V. Chubukov, S. Sachdev, A. Sokol
We present a theoretical expression for the spin-echo decay rate, 1/T_2G, in the quantum-critical regime of square lattice quantum antiferromagnets. Our results are in good agreeme…
Theory of Two-Dimensional Quantum Heisenberg Antiferromagnets with a Nearly Critical Ground State
Andrey V. Chubukov, Subir Sachdev, Jinwu Ye
We present the general theory of clean, two-dimensional, quantum Heisenberg antiferromagnets which are close to the zero-temperature quantum transition between ground states with a…
Theory of p-wave Pairing for He on Grafoil
A. V. Chubukov, A. Sokol
The specific heat and susceptibility data for He on Grafoil are analyzed in the framework of the Landau Fermi liquid theory. The dominant interaction between He quasipartic…
Universal Magnetic Properties of at Intermediate Temperatures
Andrey V. Chubukov, Subir Sachdev
We present the theory of two-dimensional, clean quantum antiferromagnets with a small, positive, zero temperature () stiffness , but with the ratio arbitrary…
