Finite temperature correlations in the one-dimensional quantum Ising model
A. Leclair, F. Lesage, S. Sachdev +1
We extend the form-factors approach to the quantum Ising model at finite temperature. The two point function of the energy is obtained in closed form, while the two point function…
Spin-Peierls states of quantum antiferromagnets on the lattice
Subir Sachdev, N. Read
We discuss the quantum paramagnetic phases of Heisenberg antiferromagnets on the 1/5-depleted square lattice found in . The possible phases of the quantum dimer model o…
Universal low-temperature properties of quantum and classical ferromagnetic chains
Minoru Takahashi, Hiroaki Nakamura, Subir Sachdev
We identify the critical theory controlling the universal, low temperature, macroscopic properties of both quantum and classical ferromagnetic chains. The theory is the quantum mec…
Multicritical crossovers near the dilute Bose gas quantum critical point
Kedar Damle, Subir Sachdev
Many zero temperature transitions, involving the deviation in the value of a conserved charge from a quantized value, are described by the dilute Bose gas quantum critical p…
