nal time, the atom remains in its initial excited state for the rst example and the particle remains behind the barrier for the second. We then ask what weak values are predicted in the physical environment of the atom (to which no net energy has been transferred) and in the region beyond the barrier (to which the particle has not tunneled). Previous work suggests that very large weak values might arise in these regions for long durations between pre- and post-selection times. Our calculations…

The retrocausal tip of the quantum iceberg
We discuss the fundamental role of non-events in quantum mechanics. The (non-)emission of a particle from an isolated atom under the uncertainty principle is studied with the aid of two novel
Interaction-Free Effects Between Distant Atoms
TLDR
A Gedanken experiment is presented where an excited and a ground-state atom are positioned such that, within the former’s half-life time, they exchange a photon with 50% probability, and the result is apparently precluding entanglement, which gives rise to the Quantum Zeno effect.
Some Notes on Counterfactuals in Quantum Mechanics
TLDR
A weak value analysis of quantum oblivion is performed and some new avenues for further research are suggested that offer a realistic, simple and intuitively appealing explanation to the unique role of quantum non- Events as well as to the foundations of QM.

The question in the title may be answered by considering the outcome of a ``weak measurement'' in the sense of Aharonov, Albert, and Vaidman. Various properties of the resulting time are discussed,
Time-dependent quantum weak values : Decay law for postselected states
Weak measurements offer insights into the behavior of quantum systems. Combined with postselection, quantum mechanics predicts a range of experimentally testable phenomena. In this paper I consider

The spin–statistics connection, in particular the Pauli exclusion principle (PEP), plays a very important role in our comprehension of matter and nature. Presently, the PEP violation, possible within
Quantum interference experiments, modular variables and weak measurements
We address the problem of interference using the Heisenberg picture and highlight some new aspects through the use of pre-selection, post-selection, weak measurements and modular variables. We

TLDR
A description of quantum systems at the time interval between two successive measurements is presented, and how this approach leads to a new concept: a weak value of an observable.
Surprising quantum effects
Abstract We consider circumstances wherein a quantum-mechanical system is subjected to a varied sequence of measurements, some of which are substantially more precise than others. Such systems are
How the result of a measurement of a component of the spin of a spin-1/2 particle can turn out to be 100.
We have found that the usual measuring procedure for preselected and postselected ensembles of quantum systems gives unusual results. Under some natural conditions of weakness of the measurement, its
Construction of Aharonov–Berry's superoscillations
A simple method is described for constructing functions that superoscillate at an arbitrarily chosen wavelength scale. Our method is based on the technique of oversampled signal reconstruction. This
A time-symmetric formulation of quantum mechanics
Quantum mechanics allows one to independently select both the initial and final states of a single system. Such pre- and postselection reveals novel effects that challenge our ideas about what time
