This article aims at discussing the cosmological constant problem at a pedagogical but fully
technical level. We review how the vacuum energy can be regularized in flat and curved …

Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will
be the world's brightest neutron source. As such, it has the potential for a particle physics …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

The numerical prediction, theoretical analysis, and experimental verification of the
phenomenon of wave packet revivals in quantum systems has flourished over the last …

The phenomena implied by the existence of quantum vacuum fluctuations, grouped under
the title of the Casimir effect, are reviewed, with emphasis on new results discovered in the …

We study noncommutative geometry at the quantum mechanics level by means of a model
where noncommutativity of both configuration and momentum spaces is considered. We …

This article deals with the interplay between the properties of the neutron and its basic
interactions. Many of the neutron's properties underlie a simple quark model, and we …

The existence of a minimum observable length and/or a maximum observable momentum is
in agreement with various candidates of quantum gravity such as string theory, loop …

Among the known particles, the neutron is special because it provides experimental access
to all of the four fundamental forces and a wide range of hypothetical interactions. Despite …

The infinite square well and the attractive Dirac delta function potentials are arguably two of
the most widely used models of one-dimensional bound-state systems in quantum …
