The project focuses on finite geometries (in particular geometries over rings) and their role as a link and unifying platform between at first sight rather different domains of physics and chemistry.
Quantum information theory:
Here we focus our attention at two goals: On the one hand, we aim at extending our finite-ring-geometrical theory of the generalized Pauli group of a single qudit to the case of multiple qudits. On the other hand, we plan to ascertain which geometrical and combinatorial aspects of a projective ring geometry directly relate to entanglement in a given quantum system, and to which extent these entities can provide a quantitative measure for entanglement.
Chemistry of coupling:
We intend to put forward first rudimentary discrete models of chemical bonds that are fully devoid of divergences and degenerations exhibited by continuous models. As a subsequent step, we plan to explore the finest traits of hierarchical properties of chemically bonded systems, with a particular focus on a gradual disappearance of the boundary between individual building blocks, and, hence, of the dichotomy 'the object and its surroundings'.
Stringy black holes:
We would like to inspect which finite geometries underlie the (already known and yet to be unveiled) relations between black-hole entropies and entanglement invariants characterizing multi-qubit/qudit systems. A particular attention will be paid to the role of the Fano plane and its recently discovered non-unimodular 'Snowflake' generalizations, generalized polygons of small order, and biplanes of small order.
The main outcome of the project should be:
