Plutonium hexaboride is a correlated topological insulator.
We predict that plutonium hexaboride (PuB(6)) is a strongly correlated topological insulator, with Pu in an intermediate valence state of Pu(2.7+). Within the combination of dynamical mean field theory and density functional theory, we show that PuB(6) is an insulator in the bulk, with nontrivial Z(2) topological invariants. Its metallic surface states have a large Fermi pocket at the X[over ¯]...
متن کاملHow Trivial Is Trivial
This question is, I feel, in the same kind of idiot category as how long is a piece of string? interviewed recently by a journalist planning to write an article about the women (like me) who conduct 'Auntie' columns in women's magazines, I was asked what proportion of the letters I received each week could be labelled trivial. Her eyebrows shot up when I said that in my view, no human problem w...

متن کاملΦ4 Theory Is Trivial
Perturbative study of many quantum field models has lead to many impressive results: beta functions for QED and for the Φ4 theory are known up to the fifth order whereas that of QCD up to the fourth order [1]-[7]. These studies however are based on the expansion in the small coupling constant such that the behavior at large couplings is completely missed. Although the possibility of a perturbat...
متن کاملIs computationalism trivial?
In this paper, I want to deal with the triviality threat to computationalism. On one hand, the controversial and vague claim that cognition involves computation is still denied. On the other, contemporary physicists and philosophers alike claim that all physical processes are indeed computational or algorithmic. This claim would justify the computationalism claim by making it utterly trivial. I...
