Digitalna holografija u uvjetima niske razine signala
Collecting optical information in digital holography, under conditions of illumination intensity weaker than the detector noise level, seems as an impossible mission. However, our colleague N. Demoli collaborating with H. Skenderović and M. Stipčević (IRB) shows, in the work taken at IF’s Coherent Optics Laboratory and recently published in Optics Letters, that even under conditions of extremely low illumination level digital hologram’s parameters can be successfully analysed and optimized.

Center of Excellence for Advanced Materials and Sensing Devices
Minister of science, education and sports, dr. Vedran Mornar, declared Croatian scientific centers of excellence at the meeting on the National council for science, higher education and technological development held on November 10, 2014. The largest of seven new centers is the Center of Excellence for Advanced Materials and Sensing Devices (CEMS) hosted by Ruđer Bošković Institute and Institute of Physics.

Magnetic anisotropy in spin tetramer system SeCuO3
Magnetism of S=1/2 spin systems is usually described by isotropic Heisenberg exchange energy. At variance, SeCuO3 represents a system revealing anistropic exchange interaction, thoroughly analyzed and modelled in the work of our colleague Mirta Herak and collaborators from IF, IRB and EPFL. Comprehensive research, using torque-magnetometry and ESR spectroscopy, has been recently published in Physical Review B.

Skyrmion lattice manipulation by static electric field in Cu2OSeO3
In itinerant Skyrmion systems the Skyrmion lattice is susceptible to conduction-electron currents as well as to thermal gradients. Article recently published in Physical Review Letters, shows how and why static electric field can manipulate the Skyrmion lattice in the insulating Cu2OSeO3. The related work is realized in international collaboration of several laboratories, involving our colleague Ivica Živković and his successful research of this system taken during last several years.

First observation of excitons at metal surfaces
In contrast to semiconductors and insulators, the observation of excitons in metals is limited by ultrafast screening of primary electron-hole Coulomb interaction. Following the work of our colleague B. Gumhalter and coauthors, who predicted a substantial enhancement of exciton lifetime at surfaces of some metals, the study of ultrafast electron dynamics at Ag(111) surfaces by time resolved three-photon photoemission carried out in collaboration with H. Petek and his team from University of Pittsburgh, revealed for the first time the presence of exciton transients in metals. The report is published in Nature Physics.

3D Heisenberg fluctuations in the skyrmion system Cu2OSeO3
How does the universality principle of phase transitions manifest itself in cases of complex long-range order, like a helimagnet one involving skyrmion-lattice segment in the phase diagram? The latter is a subject of the just published Rapid Communication article of our colleague Ivica Živković, realized in collaboration with coauthors from EPFL and Paul Scherrer Institute.

Dynamics of microscopic phases in sol-gel transition of gelatine
According to recently published work of our colleagues from the Faculty's Department of Physics, Damjan Pelc, Miroslav Požek and Mario Basletić, together with Sanjin Marion, PhD student from our Institute, a standard percolation model of gelatine gelling has to be upgraded by a more sophisticated one. Their work is published in Soft Matter, a laeading journal in the field

Nature Communications and Nano Letters simultaneously on graphene intercalations!
Only in rare occasions it happens that the two highest-ranking scientific journals report, in the two complementary articles, on the research results of our colleagues from the same laboratory. And equally good news is that Marin Petrović, IF’s PhD student, is a leading author of the Nature Communications article, published in co-authorship with our colleagues I. Šrut, I. Pletikosić, M. Milun, P. Pervan, M. Kralj and other collaborators from abroad!

New insight into the cuprate superconductors’ phase diagram
Neven Barišić, external collaborator at Institute of Physics' projects, and our colleague Ana Smontara have published, on basis of experimental work performed in part in our laboratories, within broad international collaboration, an article in PNAS (USA). The article documents ubiquitous presence of both linear and quadratic resistivity dependences in pseudogap phase of high temperature superconductors and shed new light on the phase diagram of these still enigmatic systems.
