We present evidence that the two-dimensional bulk of monolayer WTe2 contains electrons
and holes bound by Coulomb attraction—excitons—that spontaneously form in thermal …

Moiré materials with superlattice periodicity many times the atomic length scale have shown
strong electronic correlations and band topology with unprecedented tunability. Non-volatile …

Symmetry-protected topological crystalline insulators (TCIs) have primarily been
characterized by their gapless boundary states. However, in time-reversal-(T-) invariant …

Abstract Systems combining superconductors with topological insulators offer a platform for
the study of Majorana bound states and a possible route to realize fault tolerant topological …

Van der Waals (vdW) magnets both allow exploration of fundamental 2D physics and offer a
route toward exploiting magnetism in next generation information technology, but vdW …

Quantum spin Hall (QSH) insulators, with their unique helical edge states where
counterpropagating edge channels possess opposite spins, have attracted broad interest …

Quantum spin Hall (QSH) insulators are a topologically protected phase of matter in two
dimensions that can support non-dissipative spin transport. A hallmark of the phase is a pair …

Quantum spin Hall (QSH) insulators are topologically protected phases of matter in two
dimensions that can support a pair of helical edge states surrounding an insulating bulk. A …

The physical descriptions of known materials are based on quantum mechanics, which
describes how atoms bond and electrons interact at a fundamental level. However, there is …

Recently, models with long-range interactions—known as Hatsugai-Kohmoto (HK) models—
have emerged as a promising tool to study the emergence of superconductivity and topology …
