We carry out a decoherent-histories analysis of the arrival-time problem, taking advantage of
a recently demonstrated connection between time-ordered strings of projection operators …

We outline an approach to calculating the quantum mechanical propagator in the presence
of geometrically nontrivial Dirichlet boundary conditions. The method is based on a …

We consider the Rényi entanglement entropy of bosonic Tomonaga-Luttinger liquids under
a particle bipartition and demonstrate that the leading order finite-size scaling is logarithmic …

The problem of finding the exact spacetime particle's propagator in the presence of a
potential step (interface between different materials) is revisited. In contrast to the …

Computational models of reaction–diffusion systems involving low copy numbers or strongly
heterogeneous molecular spatial distributions, such as those frequently found in cellular …

It is of interest in a variety of contexts, and in particular in the arrival time problem, to
consider the quantum state obtained through unitary evolution of an initial state regularly …

Quantum weak measurements with states both pre-and post-selected offer a window into a
hitherto neglected sector of quantum mechanics. A class of such systems involves time …

We consider a number of aspects of the problem of defining time observables in quantum
theory. Time observables are interesting quantities in quantum theory because they often …

Building on mathematical similarities between quantum mechanics and theories of diffusion-
influenced reactions, we develop a general approach for computational modeling of …

We present one another consideration of the propagator for a quantum particle in the
presence of the step potential. This problem has been under treatment several times both as …
