Dear Dr. Troyer, I am trying to calculate the observables such as binder cumulant and specific heat as a function of temperature (range 5K - 700 K) for bcc chromium in order to determine the Neel temperature by considering the Heisenberg spin 1/2 antiferromagnet model. After reading through the ALPS web documentation, i got the impression that i can use the dirloop_sse binary to accomplish the task. But, the observables like binder cumulant and specific heat are not specifically mentioned in the the list of observables which can be calculated by using the dirloop_sse program. it is also written that "Other observables might also be available depending on the exact version of the application" . The ALPS version that i have installed is : alps-2.2.b3-r7462-src-with-boost. Does it mean that i will be able to calculate the binder cumulant and specific heat. please provide me some details regarding this issue.
I am eagerly looking forward for your suggestions. I thank you in advance for your time and consideration.
with best regards Sunil
Hi Sunil,
you might get faster answers if you address your question to the whole list and not just me. To answer your question, just take a look at the documentation page: http://alps.comp-phys.org/mediawiki/index.php/Documentation:dirloop_sse
and yes, there is enough being recorded to get the Binder cumulant. You can also get the specific heat from the expansion orders <n^2> and <n>
