Finitely unstable theories and computational complexity

open access: yes, 2014
The complexity class $NP$ can be logically characterized both through existential second order logic $SO\exists$, as proven by Fagin, and through simulating a Turing machine via the satisfiability problem of propositional logic SAT, as proven by Cook.

High-efficiency computational methodologies for electronic properties and structural characterization of Ge-Sb-Te based phase-change materials

open access: yesnpj Computational Materials
Theoretical simulation of phase change materials such as Ge-Sb-Te has suffered from two methodological issues. On the one hand, there is a lack of efficient band gap correction method for density functional theory that is suitable for these materials in ...
