Dear Quantum-ESPRESSO users,

I am using QE for simulations of transition metal clusters. My question 
is where the code places the vacuum level in such calculations 
(nonperiodic systems in a big cell) ? To formulate differently, is it 
possible to compare directly KS eigenvalues from different calculations ?


Thanks,
Vladan Stevanovic
