It is only exactly at the critical temperature that this CFT result works. You haven't mentioned if you have used the critical temperature when you did the monte-carlo. At/near critical point, ...

Is there any model in statistical physics which has the ratio of specific heat exponent to correlation length exponent, $\alpha/\nu \approx 2.44$?

I made a very simple mistake of plotting Specific heat and not Specific heat per spin. It is specific heat per spin that scales as $L^{\alpha/\nu}$. And hence, the actual value from the data of my ...

That $1/\sqrt{2}$ factor is for the normalization. i.e. to ensure that $\langle 1 0 | 1 0\rangle = 1$ where $\langle 1 0 |$ is the conjugate transpose of $|1 0\rangle$

I would like to add that it is very important to know what you can find out without knowing the exact solution. Kardar's book "Statistical physics of fields" teaches that in a very engaging way. To ...

Temperature in the classical model is mapped to imaginary time in the quantum model. By analytic continuation, one can obtain the real-time evolution. The matrix elements of the time-evolution ...
