Query: Charge ordering in the three-dimensional Coulomb glass at finite
  temperatures and low disorders   In this paper, we have studied the three dimensional Coulomb glass lattice
model at half-filling using Monte Carlo Simulations. Annealing of the system
shows a second-order transition from paramagnetic to charge-ordered phase for
zero as well as small disorders. We have also calculated the critical exponents
and transition temperature using a finite sizing scaling approach. The Monte
Carlo simulation is done using the Metropolis algorithm, which allowed us to
study larger lattice sizes. The transition temperature and the critical
exponents at zero disorder matched the previous studies within numerical error.
We found that the transition temperature of the system decreased as the
disorder is increased. The values of critical exponents $\alpha$ and $\gamma$
were less and value of $\nu$ more than the corresponding zero disorder values.
The use of large system sizes led to the correct variation of critical
exponents with the disorder.
