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 …

This paper reviews recent experimental and theoretical work on some low-index surfaces of
the group V semimetal bismuth. The main focus is on the geometric and electronic structure …

Monolayer graphene exhibits many spectacular electronic properties, with superconductivity
being arguably the most notable exception. It was theoretically proposed that …

In crystalline materials, electron-phonon coupling (EPC) is a ubiquitous many-body
interaction that drives conventional Bardeen-Cooper-Schrieffer superconductivity. Recently …

Angle resolved photoemission spectroscopy (ARPES) is commonly known as a powerful
probe of the one-electron removal spectral function in ordered solid state. With increasing …

The significant progress in angle-resolved photoemission spectroscopy (ARPES) in last
three decades has elevated it from a traditional band mapping tool to a precise probe of …

Kagome-nets, appearing in electronic, photonic and cold-atom systems, host frustrated
fermionic and bosonic excitations. However, it is rare to find a system to study their fermion …

We have performed a systematic angle-resolved photoemission spectroscopy (ARPES)
study of the high-T c cuprates La 2− x Sr x CuO 4, ranging from the underdoped insulator to …

Electron–phonon coupling and the emergence of superconductivity in intercalated graphite
have been studied extensively. Yet, phonon-mediated superconductivity has never been …

ITER will use beryllium as a plasma-facing material in the main chamber, covering a total
surface area of about 620 m 2. Given the importance of beryllium erosion and co-deposition …
