Low-temperature asymptotics of integrable systems in an external field
Oct, 2006Citations per year
Abstract: (arXiv)
An asymptotic low-temperature expansion is performed for an integrable bosonic lattice model and for the critical spin-1/2 Heisenberg chain in a magnetic field. The results apply to the integrable Bose gas as well. We also comment on a high-temperature expansion of the bosonic lattice model.- 05.30.Jp
