Query: Kondo temperature of Anderson impurity model in a quantum wire with
  spin-orbit coupling   We use two different methods, the Hirsch-Fye quantum Monte Carlo simulation
and the slave-boson mean field analysis to estimate the effect of spin-orbit
coupling on the Kondo temperature in a quantum wire. In quantum Monte Carlo
simulation, we calculate the product of spin susceptibility and temperature for
different spin-orbit couplings and impurity energies. The variation of the
Kondo temperature is estimated via the low temperature universal curves. In the
mean field analysis, the Kondo temperature is estimated as the condensation
temperature of slave-boson. Both the two methods demonstrate that the Kondo
temperature is almost a linear function of the spin-orbit energy, and that the
Kondo temperature is suppressed by the spin-orbit coupling. Our results are
dramatically different from those given by the perturbative renormalization
group analysis.
