High-temperature superconductivity and topological phase transition are among the most debated and intriguing phenomena in modern condensed matter physics. Their combined manifestation in either a single or hybrid material structure is of great interest for exhibiting Majorana zero modes. So far, the study of topological materials and the role of electron-phonon coupling in superconductivity...
Motivated by the recently discovered superconductivity in boron-doped Sn/Si(111) with a Tc as high as 10K [1], I will focus on unconventional superconductivity of correlated electrons on the triangular lattice. I will further demonstrate the significance of Rashba spin-orbit couling for materials such as Sn/Si(111) and show that, as a consequence, the superconducting phase possesses a...
Flat bands with narrow energy dispersion can give rise to strongly correlated electronic and topological phases, especially when located at the Fermi level. Whilst flat bands have been experimentally realized in two-dimensional (2D) twisted van der Waals heterostructures, they are highly sensitive to twist angle, necessitating complex fabrication techniques. Geometrically frustrated kagome...
I will discuss topological magnetic textures, such as skyrmions, merons, and (anti)bimerons, which constitute tiny chiral whirls in the magnetic order. They are promising candidates as information carriers for next generation electronics, as they can be efficiently propelled at very high velocities employing current-induced spin torques [1]. First, I will talk about bimerons [2] and...
Scanning tunneling microscopy (STM) is a powerful local probe of correlated electronic states. We introduce a group-theoretical framework for STM analysis that decomposes images into components corresponding to irreducible representations of the local density of states, providing a real-space map of symmetry properties. This decomposition enables the direct detection of spatial...
I will discuss our recent work on various ferroelectric and multiferroic oxide material systems using scanning probe microscopy (SPM) as the main investigative tool, with a focus on nanoscale functional property measurements of individual topological defects and new SPM instrument capability developments.
The nanoscale phonon properties of BiFeO₃ structural variants have rarely been...
