In his extension of W. Siegel's ideas on string quantization, N. Berkovits made several observations which deserve further study and development. Indeed, interesting accounts of this work have already appeared in the ...

A física teòrica, la Teoria Quàntica de Camps (TQC) és un marc teòric extremadament reeixit que combina la Relativitat Especial amb la Mecànica Quàntica, permetent el diseny de models físics de les partícules subatómiques ...

We will study the Klein-Gordon's field with an homogeneous external potential, which does not depend on ħ. We will construct the Fock's space corresponding to our problem and we will see that there are phenomena of creation ...

We address the origins of the quasi-periodic breathing observed in [Phys. Rev.\ X vol. 9, 021035 (2019)] in disk-shaped harmonically trapped two-dimensional Bose condensates, where the quasi-period Tquasi-breathing~~2T/7 ...

We show the mathematical formulation of the process of pair production in electromagnetic fields for spinless particles. We compute the probability that ? pairs are created in the semiclassical approximation, and we prove ...

The goal of this master thesis was to take initial steps towards cavity-enhanced detection of single rare-earth ions in the solid state. A fibre microcavity set-up for use with Praseodymium-doped nanocrystals was designed, ...

We revisit the properties of the two-component Fermi gas with short-range interactions in three dimensions, in the limit where the s -wave scattering length diverges. Such a unitary Fermi gas pos- sesses universal thermodynamic ...

It is shown that teleparallel F(T) theories of gravity combined with Loop Quantum Cosmology support a Matter Bounce Scenario which is an alternative to the inflation scenario in the Big Bang paradigm. It is checked that ...

Interactions, in terms of both binding energies and microscopic organization, of water molecules absorbed by hydrophilic polyaniline emeraldine base have been investigated using quantum mechanical calculations, molecular ...

We introduce the probability distribution of work performed on a one- dimensional quantum system and study the cases of a single particle in a harmonic or finite well potential and of a Bose-Einstein condensate in a finite ...
