What is the factor in Temperature unit when doing thermalization
Dear Alps users, I tried to look into the examples and files in the alps directory to find the actual factor of temperature variable (T). In magnetization vs temperature plot in the example number mc-07 the plot shows temperature range of 0 to 5 in Kelvin. I need to know if the T is exactly T or with same factor. Where can I find the program to specify this details. Sometime T should be around 300-4000 K kelvin range but it still shows temperature around 5 - 8 Kelvin . Thank you, Santu Baidya
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 Matthias

Thanks for your reply. I would like to know if T is actually "T" or "T/some factor". Thanks, Santu Baidya On 13 August 2018 at 13:27, Matthias Troyer <troyer@phys.ethz.ch> wrote:

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 On 13 August 2018 at 13:36, S Baidya <santubaidya2009@gmail.com> wrote:

T is actually given in the same units as J. If you use meV for J then T is in meV, if you use K then at is in K. If you just set J=1, then T is in units of 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.

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