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.

First reported case of hydrosilane activation mediated by hydrogen quantum tunnelling

DIPC Computational and Theoretical Chemistry

By DIPC

A kinetic isotope effect (KIE) has been observed for the generation of hydrogen from the hydrolysis of a hydrosilane catalysed by a silyl-iridium(III) complex. This and other experimental evidence together with theoretical calculations have been used to demonstrate the participation of hydrogen quantum tunnelling in this catalytic process. KIE is a phenomenon associated with isotopically […]

In most physical systems, particles interact locally or at short distances only. Still, l ong-range interactions, like electromagnetic forces, play a crucial role in quantum physics and chemistry. They are a key ingredient for many phenomena, from molecular binding to high-temperature superconductivity. While their exact treatment in quantum many-body systems remains numerically challenging, analog quantum […]

Electron correlations and topology are well established as engines for surprising and potentially functional properties. Strong correlations promote quantum fluctuations, which engender abundant phases of matter and various quantum phase transitions. Meanwhile, extensive developments have taken place in noninteracting electron systems, especially those with sizable spin-orbit couplings. It can reasonably be expected that the intersection […]

Several classes of correlated electron systems such as cuprates, iron-pnictides, iron-chalcogenides, and several heavy-fermion compounds, have been identified as unconventional superconductors. More recently, superconductivity with unconventional features has also been identified in twisted bilayer graphene. In this vein, the electronic correlations intrinsically present in transition metal dichalcogenides (TMDs), a family of layered materials, are promising […]

When the surface of a perfect conductor is structured at a length scale much smaller than the operating wavelength, geometrically induced surface electromagnetic modes can be supported. Owing to their similarities with the surface plasmon polaritons in the optical regime, these surface electromagnetic modes were named spoof surface plasmons. A new review provides a detailed […]

Graphene is an exceptional material with attractive properties to explore fundamental physics and for use in technological applications. While ideal graphene is non-magnetic, custom-shaped graphene nanostructures can be designed to exhibit complex magnetic phenomenology, with promising possibilities for a new generation of nanoscale spintronics devices. In fact, graphene π magnetism is more delocalized and isotropic […]

Twisted bilayer graphene (TBG) has taken the spotlight in the condensed matter community since the discovery of correlated phases. Now, a team of researchers studies heterostructures of TBG and hexagonal boron nitride (hBN) using an atomistic tight-binding model together with semi-classical molecular dynamics to consider relaxation effects. Isolated atomic planes, two-dimensional (2D) materials, like graphene […]

The so-called van der Waals materials consist of two-dimensional layers bound by weak van der Waals forces. After the isolation of graphene, the field of two-dimensional van der Waals materials has experienced an explosive growth and new families of two-dimensional systems and block-layered bulk materials, such as tetradymite-like topological insulators – electronic materials that have […]

The scattering of conduction electrons in metals due to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has as a consequence that, in contrast to ordinary metals, the resistance reaches a minimum as the temperature is lowered […]
