In this work we present a dynamical approach to quantum logics. By changing the standard formalism of quantum mechanics to allow non-Hermitian operators as generators of time evolution, we address the question of how can ...

Let U be a unitary operator defined on a separable infinite-dimensional complex Hilbert space H. Under suitable positivity and regularity assumptions, expressed in terms of higher order commutators, we prove the existence ...

Different aspects of quantum mechanical detection processes are studied aiming for the construction of a framework where these interactions play a central role in the description of physical phenomena. Detections are ...

We study nonequilibrium quantum phase transitions in the XY spin 1/2 chain using the C* algebra. We show that the well-known quantum phase transition at a magnetic field of h = 1 also persists in the nonequilibrium setting ...

In vertebrates, brain size variability relates to two main parameters: body size and ecological factors (in particular diet and foraging strategy). It has been considered by many authors that evolutionary brain growth is ...

ABSTRACTQuantum mechanics dictates bounds for the minimal evolution time between predetermined initial and final states. Several of these quantum-speed-limit (QSL) bounds were derived for nonunitary dynamics using different ...
