Hello, actually I am a newbie in solid state physics computational and I am starting using VASP. I am practicing to do calculation with bulk Si. I want to calculate the cohesive energy of Si. As I know that cohesive energy equals to the difference between bulk energy/atom and single atom...

Hello, I am going to determine the bulk modulus of Silicon by using Murnaghan equation. Anyone can tell me how to do Mrnaghan equation fitting? If u kindly give me an example of code, it will be great!

Hello, I need to do fitting using Birch-Murnaghan equation to determine the equilibrium lattice constant. I want to use originlab, anyone can help me?

Oh unfortunately I have a task to solve it usi b g image charge

Thanks all

So how to solve it?

The electric force cancel each other and the magnetic field exerted by each charges are opposite but opposite direction. How?

Anyone can help me how to argue that interaction lagrangian is invariant under gauge transformation?

I have a problem. Anyone can help me? Two equal charges q move with equal velocity v. What is the force acting between two charges? The distance between charges is R and the angle between R and v is A.
