Donostia International Physics Center (DIPC) is a singular research center born in 2000 devoted to research at the cutting edge in the fields of Condensed Matter Physics and Materials Science. Since its conception DIPC has stood for the promotion of excellence in research, which demands a flexible space where creativity is stimulated by diversity of perspectives. Its dynamic research community integrates local host scientists and a constant flow of international visiting researchers.
Concluding that the neutrino is a Majorana particle would be really a turning point in our understanding of the universe. It would mean the non-conservation of a magnitude called the leptonic number, one of the key characteristics in a fermion, meaning that there would be an explanation to the matter-anti matter asymmetry: the creation of […]
Transition metal dichalcogenides (TMDs) are layered compounds which can be thinned down to the single-layer limit. While mechanical exfoliation generates atomically thin TMD flakes possessing an area of a few square microns, chemical and physical methods provide high-quality monolayers on large-area substrates, which are suitable for actual technological applications. TMDs are a class of van […]

Usually, optical activity is understood as the ability some substances have to change the handedness of polarized light when it goes through them. Molecules that show optical activity have no plane of symmetry. So-called chiral matter broadly describes structures for which left- or right-handed mirror images are non-superimposable, or, equivalently, that lack improper rotation axes […]
Graphene nanoribbons (GNRs), are strips of graphene with ultra-thin width (<50 nm). Graphene ribbons were introduced as a theoretical model by Mitsutaka Fujita and coauthors to examine the edge and nanoscale size effect in graphene. Now, a team of researchers reports the generation of net spins on chiral GNRs (chGNRs) by ketone functionalization. GNRs are […]
A gravitational lens is any object that deflects light by gravitation as described by the general theory of relativity; it is analogous to a lens in optics. The prediction of a gravitational lensing effect was confirmed repeatedly in observations on quasars. In 1979 an apparently double quasar was discovered, due to the multiple image of […]
When talking about molecules, “open shell” signifies that there are unpaired electrons. In terms of molecular orbital theory, it means that some molecular orbitals are singly occupied. Organic open-shell compounds are extraordinarily attractive materials for their use in molecular spintronics. In spintronics, new memory and logic devices are being developed based on the use of […]
Imagine a conductor or a semiconductor through which a current is flowing. Then we apply a strong transverse magnetic field. As a result, we can measure a potential difference at right angles to both the current and the field caused by the deflection of charge carriers by the field. This effect was described by Edwin […]
White dwarfs are the degenerate remnant of stars with masses lower than 10 times that of the Sun and the endpoint of stellar evolution for more than 97% of Galactic stars. White dwarfs are an important tool in studying the star formation history of the Milky Way, the late phases of stellar evolution, and to […]

If we are asked what a metal is, most likely we would think almost automatically in those elements that we see as lustrous solids, good conductors of heat and electricity, that tend to form positive ions, and with a particular chemical bond that keep metal atoms in place, the metallic bond. And all of this […]
A quasicrystal is a solid structure in which there is long-range incommensurate translational order and a long-range orientational order with a point group. Translated, this simply means that a quasicrystal is ordered but not periodic and, still, it can fill space completely. In two dimensions, the fivefold symmetry of a pentagon is an example of […]
