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.

Quantum size-effect in graphene nanostructures
Size-effect plays important role in classical statistical physics and often serves to demonstrate boundary between the quantum and macro-world. How the size of the system determines behaviour of the quantum two-dimensional graphene nanostructures is shown in the articles of our colleague Marko Kralj and his collaborators from Universität zu Kőln, published in Physical Review Letters.

Nonlocal effective interactions in soft colloids
Our colleague Antonio Šiber has recently published, in collaboration with Primož Ziherl from Jožef Štefan Institute, an article in Physical Review Letters. Their work deals with the response of a colloid’s particles to deformations, showing that the particle designations like “soft” and “hard” do not span a complete basis one requires for qualitative and quantitative description of particles stressed by mutual contacts.

Tunable Polaronic Conduction in Anatase
Our colleague Osor Barišić has recently published, in collaboration with international research team of scientists from USA, Switzerland and S. Korea, an article in Physical Review Letters, decorated by the ‘Editor’s Choise’ mark. Employing ARPES in studies of Anatase, a structural modification of TiO2, the authors identify large polarons as quasiparticles underlying its electronic spectrum. Polaronic electrical conduction was found tunable in varying concentration of oxygen vacancies.

Rigid mesh of DNA polyelectrolytes
Our colleagues, K. Salamon, D. Aumiler and T. Vuletić along with G. Pabst from University of Graz have published an article in Macromolecules, a top journal in polymer science. Utilizing different experimental techniques and studying both the structure and the dynamics they have demonstrated the existence of a rigid mesh formed by the polyelectrolytes deoxyribonucleic acid (DNA) and hyaluronic acid (HA).

Graphene stairways to Carbon
New fronts in epitaxial graphene research regard tailoring the growth of graphene on stepped surfaces in order to make use of periodic modulations to the electronic structure of graphene. The work of our colleagues, in particular of the leading author Iva Šrut, on the growth of graphene on stepped Ir(332) presents a significant contribution to this new topic and is just accepted for publication in Carbon.

Thermal transport in doped Mott-insulator
Our colleague Veljko Zlatić, Emeritus Scientists at Institute of Physics, has just published, in collaboration with J.K. Freericks, an article in Physical Review Letters. By analytic theoretical treatment of doped Mott insulator the authors show that, depending on temperature and physical parameters, figure-of-merit (ZT) of such a system can be enhanced to reach values of the order of 100, a distinct aim in search for new and efficient thermoelectrics.
