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.

By DIPC

Nonlinear optics is concerned with the optical properties of matter subjected to intense electromagnetic fields. For nonlinearity to manifest itself, the external field should not be negligible compared to the internal fields of atoms and molecules of which the matter consists. Lasers are capable of generating external fields sufficiently intense for nonlinearity to occur. Actually […]

A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. The study of enzymes has provided us many of the prototypical concepts of catalysis, including the idea that a catalyst lowers the barrier to reaction and thereby accelerates the approach to chemical equilibrium, without altering […]

Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen (77 K) at about 93 K. This family is known as cuprates as it can be viewed as containing anionic copper complexes […]

DIPC Electronic Properties

By DIPC

One-dimensional metal−organic chains often possess a complex magnetic structure, susceptible to modification by alteration of their chemical composition. The possibility to tune their magnetic properties provides an interesting playground to explore quasi-particle interactions in low-dimensional systems. These systems have potential applications in the fabrication of nanodevices for spin sensing, spintronics, quantum computing based on the […]

The implications of ground-state correlations on the integrability of quantum many-body systems

DIPC Quantum SystemsQuantum physics

By DIPC

A model of a physical system that can be solved exactly and the dynamics of which are characterized by regular rather than chaotic motion is called an integrable model. Integrable models can occur in Newtonian mechanics and quantum mechanics, with the harmonic oscillator being an example of such a model in both cases. Integrability has […]

By DIPC

Nanothreads are one-dimensional covalently bonded materials, with all “backbone” bonds saturated in the organic sense, the first of which was made from polymerization of benzene in the solid state. Nanothreads are thicker than conventional hydrocarbon polymers such as polyethylene and thinner than traditional nanowires: as ladder polymers, they are examples of the thinnest possible rigid […]

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 […]
