Landau theory of quantum spin glasses of rotors and Ising spins
N. Read, S. Sachdev, J. Ye
We consider quantum rotors or Ising spins in a transverse field on a -dimensional lattice, with random, frustrating, short-range, exchange interactions. The quantum dynamics are…
NMR relaxation in half-integer antiferromagnetic spin chains
Subir Sachdev
Nuclear relaxation in half-integer spin chains at low temperatures (T << J, the antiferromagnetic exchange constant) is dominated by dissipation from a gas of thermally-excited, ov…
Crossover and scaling in a nearly antiferromagnetic Fermi liquid in two dimensions
Subir Sachdev, Andrey V. Chubukov, Alexander Sokol
We consider two-dimensional Fermi liquids in the vicinity of a quantum transition to a phase with commensurate, antiferromagnetic long-range order. Depending upon the Fermi surface…
Finite Temperature Properties of Quantum Antiferromagnets in a Uniform Magnetic Field in One and Two Dimensions
Subir Sachdev, T. Senthil, R. Shankar
Consider a -dimensional antiferromagnet with a quantum disordered ground state and a gap to bosonic excitations with non-zero spin. In a finite external magnetic field, this ant…
