Engineering quantum matter - atomically well-defined topological band structures

The project focused on realizing artificial structures with engineered topological properties. We achieved significant progress on artificial lattices with tuneable band structures and on engineered systems of magnetic impurities on superconducting substrates.

We created analogues of two tight-binding models of fundamental importance: the polyacetylene (dimer) chain with topological domain-wall states, and the Lieb lattice with a flat electron band. We observed the formation of so-called coupled Yu-Shiba-Rusinov (YSR) low energy bound states, induced by impurities on superconductors. This is a promising first step for realization of novel topological states predicted in YSR lattices. In addition, we extended the theoretical understanding of these systems to disordered magnetic impurity chains and to impurities on p-wave superconductors.

Realizations of these structures open new vistas for future nanoelectronics.

Non‐Markovian Quantum Thermodynamics with Device Applications (NOMQUT)

NOMQUT work concentrated on quantification of memory effects in small quantum systems strongly coupled to the environment. The motivation was to understand how strong coupling affects both the equilibrium states of small quantum systems as well as quantum systems driven by an external drive. The project focused in particular on the flow of heat and information for such cases, and quantified them by using the BLP trace distance measure based on the density matrix of the system. The results revealed complicated and somewhat unexpected dependence of the information flow on the coupling strength, and other relevant parameters such as the number of degrees of freedom in the environment. NOMQUT results could be used to develop guidelines for environmental engineering of small quantum devices.
