Dear Sir,
We would like to address the following problems using the ALPS package.
* *
*May I kindly request if you could inform us if these problems could be done using this package? *
* *
Problem 1
I consider a bcc phase with 3.64 A as lattice parameter. We assume A, B or C (could be Ni,Ti and Nb) *can either occupy* (0,0,0) position.
I also assume X(A)=0.40 X(B)=0.40 X(C)=0.20 as composition variables
Now, I consider a 40 atom cell which can mimic the most random alloy with this composition.
Can I use your code to get the most random alloy for A, B and C. That is to say, getting the structure of this alloy with a 40 atom cell satisfying the
compositions using MC simulations at T=298.15 K
Can we add any number of elements if we are to construct a disordered alloy of say, 5 elements? Can it be done?
Problem 2
I consider a rhombohedral phase with 15-16 A approx. as lattice parameters. I have *five* different inequivalent positions which can *either be occupied * by A or B (say Ni and Fe)
I assume composition variables as X(A)=0.60 X(B)=0.40
Can in this case a 40 atom cell be used to generate the most random structure using MC simulations at T=298.15 K
Could you please suggest on these issues Sir and inform if ALPS could be used for these cases.
With regards
