described by the quantum metric of the valence-band Bloch state, has been an intriguing …

Much of the qualitative nature of physical systems can be predicted from the way it scales
with system size. Contrary to the continuum expectation, we observe a profound deviation …

In topological insulators and topological superconductors, the discrete jump of the
topological invariant upon tuning a certain system parameter defines a topological phase …

The correlation functions related to topological phase transitions in inversion-symmetric
