Hi,
In 3D what we measure is proportional to rho_s*L^2. What we calculate here is the winding number fluctuation and you will have to convert it manually to the right stiffness for your model.

Dear all,
I am now studying the 3D bose glass model. I got some confusionsabout the stiffness. By using SSE, I got the stiffness is 2.2427 from the following setting:
LATTICE_LIBRARY="lattices.xml"; LATTICE="inhomogeneous simple cubic lattice"; L=5; MODEL_LIBRARY="models.xml"; MODEL="hardcore boson"; t = 1.0; T = 0.1; delta=10.0; SWEEPS=500000; THERMALIZATION=10000; EPSILON=0.25; { DISORDERSEED = 34275; mu=delta*2*(random()-0.5); }
My question is: if this stiffness is rescaled one, namely ρs*L^4=2.2427 ? The power 4th is from Fisher argument. Thank you in advance!
Best, Xiaoquan
