Study of light nuclei by 13C beam induced reactions
-
Lovro Prepolec The study of light nuclei is one of the most active areas in the nuclear physics today. Nuclei in the mass region A < 20 have been used as a testing sample for different theoretical models since the early days of nuclear physics. Nowadays the advent of ab initio calculations in various frameworks and the astrophysical interest makes the precise experimental data even more important. One of the topics of interest in the structure of light nuclei are the neutron-rich oxygen isotopes, starting...

Study of the thermosalient effect in N’-2-Propylidene-4-hydroxybenzohydrazide and the derivatives of oxitropium bromide
-
Teodoro Klaser Thermosalient materials, or more colloquially called jumping crystals, are a class of materials that exhibit mechanical motion as a response to the thermal stimulus. Such materials, which are capable of extremely fast and, more important, controllable energy conversion are extremely important candidates for active actuating elements, such as flexible electronic switches, displays, artificial muscles, microfluidic valves and gates, heat sensors etc. New examples of thermosalient materials are...

Study of transfer reaction properties with stable and unstable heavy ion beams
-
Petra Čolović The main subject of this thesis is to show that transfer reactions with the neutron-rich unstable beams and the heavy targets could be very adequate for the production of the neutron-rich heavy nuclei. To that purpose, the measurement of 94^Rb+208^Pb transfer reaction has been performed at the energy of about 30% above the Coulomb barrier, provided by the radioactive ion beam facility of CERN (HIE-ISOLDE). The high-resolution and high-efficiency experimental set-up consisted of a large...

Study of vector boson scattering in events with four leptons and two jets with CMS detector at the LHC
-
Duje Giljanović Studying 93 Vector Boson Scattering is crucial for understanding the electroweak symmetry breaking mechanism and it provides a complementary tool for measuring Higgs boson couplings to vector bosons. In addition, using the effective field theory (EFT) framework, one can probe the Beyond Standard Model physics through modifications of certain quartic gauge couplings. This thesis reports the first evidence, with the CMS detector, of electroweak (EW) production of leptonically decaying Z boson...

Subordinate random walks
-
Stjepan Šebek In this thesis, we consider a large class of subordinate random walks on the integer lattice \(\mathbb{Z}^d\) via subordinators with Laplace exponents which are complete Bernstein functions satisfying some mild scaling conditions at zero. Subordination is a procedure for obtaining new process from the original one. The new process may differ very much from the original process, but the properties of this new process can be understood in terms of the original process. Main results of the...

Sustav alarmina i ukupni genski izražaj u juvenilnom sustavnom eritemskom lupusu
-
Anita Lukić U ovoj studiji istraživana koncentracija i genski izražaj za alarmine S100A12, HMGB1 te njihovog receptora RAGE kod zagrebačke djece s juvenilnim sustavnim eritemskim lupusom (JSLE) te ukupni genski izražaj djece s JSLE u studiji GSE11909 iz baze GEO. Koncentracije alarmina S100A12, HMGB1 i RAGE kod djece s JSLE su bile slične koncentracijama kod zdrave djece, dok su bolesna djeca imala niži genski izražaj za S100A12, te viši za HMGB1 i RAGE, što potvrđuje hipotezu da postoji...

Jelena Dautović Organski ugljik važan je indikator globalnih promjena te sudjeluje u mnogim
biogeokemijskim procesima u moru. Ovaj rad dokumentira dinamiku promjena sadržaja i
svojstava otopljene organske tvari/ugljika, u odabranim područjima Jadrana koja su pod jakim
utjecajem unosa slatke vode kao i različitih vodenih masa: sjeverni Jadran (SJ) na profilu Rovinj
– rijeka Po, Boka kotorska i albanski šelf. Ispitivani su sadržaj i svojstva otopljenog organskog
ugljika (eng. DOC),...

Synthesis and intercalation of epitaxial graphene on iridium
-
Marin Petrović Epitaxial graphene on iridium (111) surface is considered to be one of the best systems for studying intrinsic properties of graphene due to the weak interaction with the substrate which is predominantly of the van der Waals character. In epitaxial systems, graphene’s properties can be modified or some new ones can be induced by the processes of intercalation of various atoms or molecules in between the graphene and the substrate. Therefore, a detailed understanding of the formation of...

Synthetic Lorentz force for neutral cold atoms
-
Neven Šantić Presented in this thesis are results of research on two topics in the field of cold atoms. These topics are connected by the fact they both employ laser induced forces caused by momentum transfer from photons to atoms. In both cases the laser induced forces change the velocity distribution of the atomic ensemble. In the first part of the thesis a new way to implement a synthetic Lorentz force into a cold atomic gas is presented. The synthetic Lorentz force (SLF) is based on radiation...

Synthetic magnetism in quantum gases and photonic lattices
-
Tena Dubček Many intriguing phenomena in modern physics are rooted in the coupling of electric charge to magnetic fields. However, it mostly includes quantum many-body systems, which makes these systems hard to address both experimentally—because of the rather extreme conditions they usually require, and theoretically—because of the exponential dependence of the required classical computer memory on the number of quantum system constituents. The solution is found by following Feynman’s idea of the...
