Correlated interstitial subsystem
We analyse Coulomb interaction, hybridization and localization in the electronic states that form the electride subsystem.

Many-body physics of interstitial electrons.
We use advanced first-principles and many-body approaches to study how electrons in the voids, channels and layers of crystals determine the electronic, magnetic and quantum properties of electrides.
Research & results →Our focus
A coherent research programme in electride physics.
Magnetism without magnetic atoms
We study how confined interstitial electrons acquire local moments, magnetic order and correlated quantum behaviour.
Low-dimensional quantum effects
We investigate the consequences of confinement, pressure, layer number and interfaces for transport and magnetic phases.
Selected results
Research & results
Ca under pressure
DFT+DMFT calculations show that weak Coulomb correlations are important for reproducing the sequence of high-pressure electride phases of elemental calcium.
Open →Ca₂N and dimensionality
Pressure-driven changes of the interstitial electronic subspace are linked to localization, transport behaviour and volume collapse.
Open →Li₈Au and local moments
Many-body calculations identify magnetic moments associated with interstitial quasi-atomic states rather than atoms of the crystal framework.
