The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy
(STM) have become indispensable tools in the study of correlated quantum materials. Both …

Motivated by recent experiments on Kondo insulators, we theoretically study quantum
oscillations from disorder-induced in-gap states in small-gap insulators. By solving a non …

Searching for heavy fermion (HF) states in non–f-electron systems becomes an interesting
issue, especially in the presence of magnetism, and can help explain the physics of complex …

We investigate collective dynamics in a binary mixture of programmable robots in
experiments and simulations. While robots of the same species align their motion direction …

Flatband systems typically host “compact localized states”(CLS) due to destructive
interference and macroscopic degeneracy of Bloch wave functions associated with a …

The heavy-fermion metal CeCu 2 Si 2 was the first discovered unconventional, non-phonon-
mediated superconductor and, for a long time, was believed to exhibit single-band d-wave …

Quantum many-body systems, particularly, the ones with large near-EF density states, are
well known for exhibiting rich phase diagrams as a result of enhanced electron correlations …

The study of quantum phase transitions that are not clearly associated with broken symmetry
is a major effort in condensed matter physics, particularly in regard to the problem of high …

The effective interactions between the constituents of driven soft matter generically defy
Newton's third law. Combining theory and numerical simulations, we establish that six …
