1. Kulturna dediščina in strpnostBarbara Lečnik, 2019, professional article Abstract: Pričujoč članek v sklopu projekta Escape (Interreg SIHU) je predstavitev dediščine kot pomnika preteklosti, ki je znatno zaznamoval tako slovenski kot čezmejni prostor. Prav tako želi osvetliti razsežnosti odnosa do dediščine, ki mu je mogoče slediti na vsakem koraku. Članek je razdeljen na tri sklope. Prvi sklop obravnava projekt Escape in pet tematskih sklopov v povezavi z dediščino na medregionalnem območju, ki predstavljajo pet čezmejnih turističnih produktov – pobegov, vključenih v projekt Escape. Drugi sklop se tematsko navezuje na zadnji tematski sklop, Pobeg v zgodovino izseljevanja, ki natančneje obravnava povezavo izseljevanja in kulturne dediščine na medregionalnem območju na vzorčnem primeru vasi Žepovci (EŠD 28167). Tretji sklop vsebuje seznam enot dediščine v območju vasi Žepovci.

3. Discrete symmetries in Heterotic/Ftheory duality and mirror symmetryMirjam Cvetič, Antonella Grassi, Maximilian Poretschkin, 2017, original scientific article Abstract: We study aspects of Heterotic/Ftheory duality for compactifications with Abelian discrete gauge symmetries. We consider Ftheory compactifications on genusone fibered CalabiYau manifolds with nsections, associated with the TateShafarevich group Z(n). Such models are obtained by studying first a specific toric setup whose associated Heterotic vector bundle has structure group Z(n). By employing a conjectured Heterotic/Ftheory mirror symmetry we construct dual geometries of these original toric models, where in the stable degeneration limit we obtain a discrete gauge symmetry of order two and three, for compactifications to six dimensions. We provide explicit constructions of mirrorpairs for symmetric examples with Z(2) and Z(3), in six dimensions. The Heterotic models with symmetric discrete symmetries are related in field theory to a Higgsing of Heterotic models with two symmetric abelian U(1) gauge factors, where due to the Stuckelberg mechanism only a diagonal U(1) factor remains massless, and thus after Higgsing only a diagonal discrete symmetry of order n is present in the Heterotic models and detected via Heterotic/Ftheory duality. These constructions also provide further evidence for the conjectured mirror symmetry in Heterotic/Ftheory at the level of fibrations with torsional sections and those with multisections.

4. Type II string theory on CalabiYau manifolds with torsion and nonAbelian discrete gauge symmetriesVolker Braun, Mirjam Cvetič, Ron Donagi, Maximilian Poretschkin, 2017, original scientific article Abstract: We provide the first explicit example of Type IIB string theory compactification on a globally defined CalabiYau threefold with torsion which results in a fourdimensional effective theory with a nonAbelian discrete gauge symmetry. Our example is based on a particular CalabiYau manifold, the quotient of a product of three elliptic curves by a fixed point free action of Z(2) x Z(2). Its cohomology contains torsion classes in various degrees. The main technical novelty is in determining the multiplicative structure of the (torsion part of) the cohomology ring, and in particular showing that the cup product of second cohomology torsion elements goes nontrivially to the fourth cohomology. This specifies a nonAbelian, Heisenbergtype discrete symmetry group of the fourdimensional theory.

5. Rotating solutions in critical Lovelock gravitiesMirjam Cvetič, XingHui Feng, Hong Lü, Christopher N. Pope, 2017, original scientific article Abstract: For appropriate choices of the coupling constants, the equations of motion of Lovelock gravities up to order n in the Riemann tensor can be factorized such that the theories admit a single (A)dS vacuum. In this paper we construct two classes of exact rotating metrics in such critical Lovelock gravities of order n in d = 2n +1 dimensions. In one class, the n angular momenta in the n orthogonal spatial 2planes are equal, and hence the metric is of cohomogeneity one. We construct these metrics in a KerrSchild form, but they can then be recast in terms of BoyerLindquist coordinates. The other class involves metrics with only a single nonvanishing angular momentum. Again we construct them in a KerrSchild form, but in this case it does not seem to be possible to recast them in BoyerLindquist form. Both classes of solutions have naked curvature singularities, arising because of the over rotation of the configurations.

6. Attitudes toward workplace mobbing in Slovenian research organisationsBrigita Krsnik Horvat, Milan Pagon, 2012, original scientific article Abstract: Creating a "mobbingsafe" working environment can be a real challenge; to achieve it, a better understanding of related constructs is necessary. To obtain insight into researchers' attitudes toward workplace mobbing and behavioural intentions, we used a case scenario method. The results show that respondents, on average, consider the mobbing cases presented in a questionnaire to be very serious. Their attitudes and behavioural intentions depend more on their opinion about colleagues' attitudes and related intentions and less on their own, which shows a lower integrity than desired. Low willingness to report the violator, lenient discipline sanctions and the absence of proper organisational rules create favourable conditions for workplace mobbing in Slovenian public research organisations. This paper also proposes measures based on the research findings of various authors and identifies new questions that could be addressed in further research.

7. Ivan Grohar and Oskar DevFranc Križnar, 2014, original scientific article Abstract: The new Grohar’s room in the Škofja Loka Museum that is located in a more than a thousand years old town, some kilometres northwest of Ljubljana, Slovenia, represents one of the new possibilities to popularize old local history. Ivan Grohar (1867−1911) is one of the four wellknown Slovenian painters from the beginning of the 20th century, together with Rihard Jakopič, Matija Jama and Matej Sternen. These Slovenian painters are the founders of Impressionism within the modern style. Škofja Loka became the so called Slovenian “Barbizon” (i.e. French village near Fontainebleau, once the settlement of painters) and this art and old tradition inspired another Slovenian (music) artist Oskar Dev (1868−1932), who composed some of his musical works (songs and choirs) in Škofja Loka, too. His and Grohar’s period in Škofja Loka resulted in some extraordinary art works i.e. paintings and musical works. They both were inspired by the countryside that reflected on their works. This is now one of the new Slovenian’s challenges of museology and musicology in an interdisciplinary and multidisciplinary approach so the art of painting and music could be a benefit for the visitors of this and other museums.

8. Parameter space for a dissipative FermiUlam modelDiego F. M. Oliveira, Edson D. Leonel, 2011, original scientific article Abstract: The parameter space for a dissipative bouncing ball model under the effect of inelastic collisions is studied. The system is described using a twodimensional nonlinear areacontracting map. The introduction of dissipation destroys the mixed structure of phase space of the nondissipative case, leading to the existence of a chaotic attractor and attracting fixed points, which may coexist for certain ranges of control parameters. We have computed the average velocity for the parameter space and made a connection with the parameter space based on the maximum Lyapunov exponent. For both cases, we found an infinite family of selfsimilar structures of shrimp shape, which correspond to the periodic attractors embedded in a large region that corresponds to the chaotic motion.

9. Expanded boundary integral method and chaotic timereversal in quatum billiardsGregor Veble, Tomaž Prosen, Marko Robnik, 2007, original scientific article Abstract: We present the expanded boundary integral method for solving the planar Helmholtz problem, which combines the ideas of the boundary integral method and the scaling method and is applicable to arbitrary shapes. We apply the method to a chaotic billiard with unidirectional transport, where we demonstrate the existence of doublets of chaotic eigenstates, which are quasidegenerate due to timereversal symmetry, and a very particular level spacing distribution that attains a chaotic Shnirelman peak at short energy ranges and exhibits Gaussian Unitary Ensemble (GUE) like statistics for large energy ranges. We show that, as a consequence of such particular level statistics or algebraic tunnelling between disjoint chaotic components connected by timereversal operation, the system exhibits quantum current reversals.

10. Wave equation for the Wu black holeTolga Birkandan, Mirjam Cvetič, 2014, original scientific article Abstract: Wu black hole is the most general solution of maximally supersymmetric gauged supergravity in D=5, containing U(1)(3) gauge symmetry. We study the separability of the massless KleinGordon equation and probe its singularities for a general stationary, axisymmetric metric with orthogonal transitivity, and apply the results to the Wu black hole solution. We start with the zero azimuthalangle eigenvalues in the scalar field Ansatz and find that the residuum of a pole in the radial equation is associated with the surface gravity calculated at this horizon. We then generalize our calculations to nonzero azimuthal eigenvalues and probing each horizon singularity, we show that the residua of the singularities for each horizon are in general associated with a specific combination of the surface gravity and the angular velocities at the associated horizon. It turns out that for the Wu black hole both the radial and angular equations are general Heun's equations with four regular singularities.
