Absence of near-ambient superconductivity in LuHN
Xue Ming, Ying-Jie Zhang, Xiyu Zhu +6
Recently near-ambient superconductivity was claimed in N-doped lutetium hydride (ref. 1). This induces a worldwide fanaticism about the dream of room temperature superconductivity…
Unexpected two-fold symmetric superconductivity in few-layer NbSe
Alex Hamill, Brett Heischmidt, Egon Sohn +13
Two-dimensional transition metal dichalcogenides (TMDs) have been attracting significant interest due to a range of properties, such as layer-dependent inversion symmetry, valley-c…
An unusual continuous paramagnetic-limited superconducting phase transition in 2D NbSe
Egon Sohn, Xiaoxiang Xi, Wen-Yu He +9
Time reversal and spatial inversion are two key symmetries for conventional Bardeen-Cooper-Schrieffer (BCS) superconductivity. Breaking inversion symmetry can lead to mixed-parity…
Real-time Observation of Phonon-Mediated - Interband Scattering in MgB2
Edoardo Baldini, Andreas Mann, Lara Benfatto +11
In systems having an anisotropic electronic structure, such as the layered materials graphite, graphene and cuprates, impulsive light excitation can coherently stimulate specific b…
Gate tuning of electronic phase transitions in two-dimensional NbSe
Xiaoxiang Xi, Helmuth Berger, László Forró +2
Recent experimental advances in atomically thin transition metal dichalcogenide (TMD) metals have unveiled a range of interesting phenomena including the coexistence of charge-dens…
Evidence of Ising pairing in superconducting NbSe atomic layers
Xiaoxiang Xi, Zefang Wang, Weiwei Zhao +6
Two-dimensional transition metal dichalcogenides with strong spin-orbit interactions and valley-dependent Berry curvature effects have attracted tremendous recent interests. Althou…
