One of the most widely known building blocks of modern physics is Heisenberg's
indeterminacy principle. Among the different statements of this fundamental property of the …

Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

According to a number of arguments in quantum gravity, both model-dependent and model-
independent, Heisenberg's uncertainty principle is modified when approaching the Planck …

The presence of noise or the interaction with an environment can radically change the
dynamics of observables of an otherwise isolated quantum system. We derive a bound on …

We review the construction and use of complex potentials in reactive scattering and other
molecular collisions to calculate continuum quantities (such as state-to-state transition …

The issue of tunneling time is replete with controversy and paradoxes. The controversy
stems from the fact that many tunneling time definitions seem to predict superluminal …

Even for simple systems, the interpretations of new attosecond measurements are
complicated and provide only a glimpse of their potential. Nonetheless, the lasting impact …

The question of how long it takes a particle to tunnel through a potential barrier has been a
subject of intense theoretical debate for the last 80 years. In this decade of attosecond …

Quantum speed limits set an upper bound to the rate at which a quantum system can evolve.
Adopting a phase-space approach, we explore quantum speed limits across the quantum-to …

This book concerns the foundations of Quantum Gravity, in particular from a conceptual point
of view. It provides a self-contained introduction to this topic, resting on particular features of …
