Ground state angular momentum, spectral asymmetry, and topology in chiral superfluids and superconductors
Teemu Ojanen
Recently it was discovered that the ground state orbital angular momentum in two-dimensional chiral superfluids with pairing symmetry depends on the winding number $…
Chern mosaic - topology of chiral superconductivity on ferromagnetic adatom lattices
Joel Röntynen, Teemu Ojanen
In this work we will explore the properties of superconducting surfaces decorated by two-dimensional ferromagnetic adatom lattices. As discovered recently [Röntynen and Ojanen, Phy…
Topological superconductivity in ferromagnetic atom chains beyond the deep-impurity regime
Kim Pöyhönen, Alex Westström, Teemu Ojanen
Recent developments in the search for topological superconductivity have brought lattices of magnetic adatoms on a superconductor into intense focus. In this work we will study fer…
Visualizing the chiral anomaly in Dirac and Weyl semimetals with photoemission spectroscopy
Jan Behrends, Adolfo G. Grushin, Teemu Ojanen +1
Quantum anomalies are the breaking of a classical symmetry by quantum fluctuations. They dictate how physical systems of diverse nature, ranging from fundamental particles to cryst…
