T is always given in the same units that you use for J

Thank you very much Matthias. This is the answer I wanted. if you kindly can tell me the particular program I should look to find these factors and their units in the alps/ directory it would be very helpful.
Because I can get "magnetization vs temp" from Ising model also I can get "magnetization vs temp" from spin model. Is it that in both cases T in unit of J ? Is it that T is actually (T/J) or (T/J.S), where S is spin value.

So if I can get those programs where this is mentioned I can understand these better.


Thanking you,

Santu

So, My question is how the temperature scale is given in the code. Can anyone please tell me. For example, in the Susceptibiliy vs temp plot the unit is given as {T/J}. Is it for each other thermalization method. Is it (T/J) or (T/J.S) ?

Thanks,

Santu

Thanks for your reply. I would like to know if T is actually "T" or "T/some factor".


Thanks,

Hi

T is in the same units that you use to specify coupling energy scales. If you use Kelvin for couplings, then T will also be in Kelvin
