... where α is a c-number. This implies tr ( Âm ρ̂ ) = tr  ρ̂ , with m = 0, 1, 2, 3..., and the above statement follows. For a pure state ρ̂ = |ψ⟩⟨ψ|, we return from (6) to the standard notion of |ψ⟩ being an eigenstate of Â. Any other, non-dispersionless observable B̂ — even if it commutes with the ...

... The use of X-ray radiation has the advantage of affecting the most strongly bound electrons, i.e. core electrons, in the molecule. The energies of such electrons are very different for different elements, and we thus have an experimental tool highly specific to different elements and local molecular ...

... Recently, we have proposed a theoretical frame for the physical origin and basis of the primary fundamental life process (Balázs, 2013,2014). It was shown, that without some elementary discussion of the (natural) biological symbolic process, this life process cannot be described adequately. ’’Natura ...

Topological quantum field theory

A topological quantum field theory (or topological field theory or TQFT) is a quantum field theory which computes topological invariants.Although TQFTs were invented by physicists, they are also of mathematical interest, being related to, among other things, knot theory and the theory of four-manifolds in algebraic topology, and to the theory of moduli spaces in algebraic geometry. Donaldson, Jones, Witten, and Kontsevich have all won Fields Medals for work related to topological field theory.In condensed matter physics, topological quantum field theories are the low energy effective theories of topologically ordered states, such as fractional quantum Hall states, string-net condensed states, and other strongly correlated quantum liquid states.
