Switching between Mott-Hubbard and Hund physics in moiré quantum simulators
Siheon Ryee, Tim O. Wehling
Mott-Hubbard and Hund electron correlations have been realized thus far in separate classes of materials. Here, we show that a single moiré homobilayer encompasses both kinds of ph…

Frozen spin ratio and the detection of Hund correlations
Siheon Ryee, Sangkook Choi, Myung Joon Han
We propose a way to identify strongly Hund-correlated materials by unveiling a key signature of Hund correlations at the two-particle level. The defining feature is the {\it sign}…

: A site-differentiated Hund metal
Taek Jung Kim, Siheon Ryee, Myung Joon Han
Magnetism in two-dimensional (2D) van der Waals (vdW) materials has lately attracted considerable attention from the point of view of both fundamental science and device applicatio…
