High Precision Measurement of the Thermal Exponent for the Three-Dimensional XY Universality Class
Physical Review B
(2006)
Abstract
Simulation results are reported for the critical point of the two-component ϕ4 field theory. The correlation-length exponent is measured to high precision with the result ν=0.6717(3). This value is in agreement with recent simulation results [Campostrini et al., Phys. Rev. B 63, 214503 (2001)] and marginally agrees with the most recent space-based measurements of the superfluid transition in He4 [Lipa et al., Phys. Rev. B 68, 174518 (2003)].
