    Mathematica Problem with numerical solution to Sch eq in Mathematica

    IN THE FOLLOWING IS IT POSSIBLE TO MODIFY THE CODE SOTHAT IT WILL GIVE ME OUTPUT FOR DIFFERENT VALUE OF 'b' (LIKE ATTACHING A FOR LOOP IN THAT AS WE DO IN C++.)Clear[k, \[Kappa], a, b, V, \[Sigma], T, g] \[Sigma] = 1; a = 0.1; b = 26; V = 3; \[Kappa] = Sqrt[V] - k*k; T =...

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    I am giving the following command for calculation of transmission probability through a double barrier but mathematica is not giving any solution to this infact it is taking a lot of time saying 'running'. I want to know that whether there is something wrong with the command lines(I am sure...

    Non central potential and energy dependence

    Could anyone tell me where can i find more about the fact that if your Hamiltonian is non-central then the total energy is not dependent only on principle quantum number n but also on l.

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    i have one problem in numerical approach that how to calculate j(inc) as how shall i know that which part is incident and which part is reflected. I also tried the transfer matrix approach but it is giving the correct result for one rectangular potential barrier but not for two.

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    i actually want to calculate the reflection coefficient for any potential.so could you suggest any numerical method to do this as i want to change the parameters (like height ,length of the potential) and get the corresponding T and R.

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    i modified my code a little bit like the following a = 1; k1 = 2; k2 = 1; s = NDSolve[{y1''[x] + k1*y1[x] == 0, y2''[x] + k2*y2[x] == 0, y3''[x] + k1*y3[x] == 0, y1[0] == y2[0], y2[a] == y3[a], y1'[0] == y2'[0], y2'[a] == y3'[a], y1[-3] == 1, y1'[-3] == 0}, {y1, y2, y3}, {x...

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    I have a question instead of using y1[a] == 1, y1'[a] == 1 as other two conditions if i will use y1[-5]==1,y1'[5]==0 as my condition then will that work? i am taking this condition as my wave func will be a plane wave for a<=0 and i can take a condition like above. please tell me where did...

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    Thanks again for the replyI am now learning to use mathematica for my computation and simulation(i used to do these with C++).I want to write a code in mathematica using Numerov method to solve this problem.But i need to know how to write code in mathematica. so is there any quick references for...

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    Thanks for the reply 1-- could you please tell me why r u putting the condition y1[a] == 1, y1'[a] == 1 when solving numerically. 2-- again even if u do it numerically the plots of y1 ,y2, y3 look same.

    Mathematica Problem with numerical solution to Sch eq in Mathematica

    I am trying to solve the potential barrier problem numerically in Mathematica I am giving the following command but it is showing error which i could not figure out a = 2; s = NDSolve[{y1''[x] + k1*y1[x] == 0, y2''[x] + k2*y2[x] == 0, y3''[x] + k1*y3[x] == 0}, {y1[0] == y2[0], y2[a] ==...
