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 …

Over the past few years, Sr2IrO4, a single-layer member of the Ruddlesden–Popper series
iridates, has received much attention as a close analog of cuprate high-temperature …

We report angle resolved photoemission experiments on the electron doped Heisenberg
antiferromagnet (Sr 1− x La x) 2 IrO 4. For a doping level of x= 0.05, we find an unusual …

We present an angle-resolved photoemission study of the electronic structure of the three-
dimensional pyrochlore iridate Nd 2 Ir 2 O 7 through its magnetic metal-insulator transition …

Excitonic insulators are usually considered to form via the condensation of a soft charge
mode of bound electron-hole pairs. This, however, presumes that the soft exciton is of spin …

Understanding the role of electron correlations in strong spin-orbit transition-metal oxides is
key to the realization of numerous exotic phases including spin-orbit–assisted Mott …

Layered perovskite iridates realize a rare class of Mott insulators that are predicted to be
strongly spin–orbit coupled analogues of the parent state of cuprate high-temperature …

We study with angle-resolved photoelectron spectroscopy the evolution of the electronic
structure of Sr 2 IrO 4, when holes or electrons are introduced, through Rh or La …

Heavy transition metal magnets with J eff= 1 2 electronic ground states have attracted recent
interest due to their penchant for hosting new classes of quantum spin liquids and …

The confluence of electron correlations and spin-orbit interactions is critical to realizing
quantum phases in 5 d transition metal oxides. Here, we investigate how the strength of the …
