... Abstract. Unitary spaces, transformations, matrices and operators are of fundamental importance in quantum mechanics. In quantum mechanics symmetry transformations are induced by unitary. This is the content of the well known Wigner theorem. In this paper we determine those unitary operators U are e ...

The absence of a turbulent solution raises a fundamental issue on whether the Navier-Stokes equation hides turbulent solutions. With this result, we must open up the possibility that turbulence is to be explained u ...

Perhaps the greatest weakness of this book is the fact that, in spite of its subtitle, which suggests a survey of philosophical responses to quantum mechanics, the book addresses only a very limited range of interpretational programs. With the exception of the many-worlds interpretation, represented ...

A simple proof of Born`s rule for statistical interpretation of quantum
... theoretical proof of this rule has been formulated till date. Initially, Born had proposed this rule based on intuition that light quanta and matter must behave in a similar manner and wave function might be analogous to electric field. In his Nobel lecture [3], Born stated, “Again an idea of Einst ...

The Born rule and its interpretation
... This account does not provide a derivation of the Born rule from first principles, but it does clarify its mathematical and physical origin. In particular, in the Copenhagen interpretation probabilities arise because we look at the quantum world through classical glasses: “One may call these uncerta ...

... The expectation value !Ψ0 |OB (j, l)|Ψ0 " = tr(ρj−l+1,j+l OB (j, l)) must be close to unity. But the expectation value tr(ρj−l+1,j ⊗ ρj+1,j+l OB (j, l)) must be small since the entropy across the cut is large. So, by Lindblad-Uhlmann theorem, the relative entropy S(ρj−l+1,j+l ||ρj−l+1,j ⊗ ρj+1,j+l ) ...
