This thesis concerns the use of density functional theory (DFT) to determine muon stopping sites in crystalline solids. New tools for carrying out these calculations are introduced and these techniques are demonstrated through the results of calculations on the skyrmion-hosting semiconductors GaV$_4$S$_8$ and GaV$_4$S$_8$ and the heavy-fermion meta...

We solve the three-particle multichannel Coulomb scattering problem with rearrangement channels without partial wave decomposition on the base of Faddeev-Merkuriev equations. Highly efficient numerical approach allowed us to perform the detailed calculations of all possible S-wave cross-sections in systems $e^+e^-\bar{p}$ and $e^+e^-\text{ He }^{++...

A search for magnetic monopoles and high-electric-charge objects is presented using 34.4 fb^{-1} of 13 TeV pp collision data collected by the ATLAS detector at the LHC during 2015 and 2016. The considered signature is based upon high ionization in the transition radiation tracker of the inner detector associated with a pencil-shape energy deposit i...

We describe the Compact Accelerator-based Neutron Source SONATE which we are aiming for to replace the close Orph{\'e}e reactor at Saclay, France. The SONATE source would serve an instrumental suite of about 10 instruments. The instruments would be split into low resolution instruments and higher resolution instruments. Our reference design is base...

The Faddeev differential equation in the total angular momentum representation are used to calculate the spectrum of the neon trimer. The Ne-Ne interatomic interaction is described by modern realistic potentials. A comparison with previously published results is done.

Significant computational resources are necessary to calculate bound and resonance states of weakly bound systems with high accuracy. The discrete-variable representation method allows to reduce the computational complexity of determining the matrix elements of operators in the frame of variational methods. In this work, the binding energies of the...

The Berry gauge field associated with adiabatic quantum evolution represents a very interesting area of research, especially for the description of non-relativistic fermions coupled to a skyrmion texture. We construct a quantum hydrodynamics model that describes the electron–skyrmion interactions, with separate descriptions of spin-up and spin-down...

Lattice Quantum Chromodynamics (LQCD) studies of light nuclei have entered an era when first results on structure and reaction properties of light nuclei have emerged in recent years, complementing existing results on their lowest-lying spectra. Although in these preliminary studies the quark masses are still set to larger than the physical values,...

Solving the homogeneous Bethe-Salpeter equation directly in Minkowski space is becoming a very alive field, since, in recent years, a new approach has been introduced, and the reachable results can be potentially useful in various areas of research, as soon as the relativistic description of few-body bound systems is relevant. A brief review of the...

We have extended [1] our previous applications of the method of unitary clothing transformations (UCTs) in mesodynamics to quantum electrodynamics (QED). An analytical expression for the QED Hamiltonian in the clothed-particle representation (CPR) has been derived. Its distinctive feature is the appearance of a new family of the Hermitian and energ...
