Pomeranchuk instability from electronic correlations in CsTiBi kagome metal
Chiara Bigi, Matteo Dürrnagel, Lennart Klebl +19
Among many-body instabilities in correlated quantum systems, electronic nematicity, defined by the spontaneous breaking of rotational symmetry, has emerged as a critical phenomenon…

Direct measurement of 2DEG states in shallow Si:Sb -layers
Frode S. Strand, Simon P. Cooil, Quinn T. Campbell +13
We investigate the electronic structure of high-density layers of Sb dopants in a silicon host, so-called Si:Sb -layers. We show that, in spite of the known challenges in produ…

An energy-dependent broadening of Rashba-like spin splitting in Au2Sb surface alloy with periodic structural defect
Jinbang Hu, Xiansi Wang, Anna Cecilie à sland +1
Here, we report a novel AuSb 2D superstructure on Au(111) that shows agreements and discrepancies to the expected electronic features of the ideal 2D surface alloys with $\sqrt{3}\…
