Bulk Superconductivity driven by Disorder-Induced Delocalization in 4Hb-Ta(SSe)
Lu Chen, Sae-Hee Ryu, Avior Almoalem +10
The unconventional superconductor 4Hb-TaS is a natural heterostructure that can be broadly understood as interleaving Mott-like and metallic layers. We study the properties of…
Spectroscopic evidence for a molecular orbital Kondo insulator
Ke-Jun Xu, Kuan H. Hsu, Nathan Giles-Donovan +13
A Kondo insulator (KI) is a prototypical example of a highly entangled phase of matter, where many-body interactions between local moments and delocalized electrons engender the no…
Strongly-coupled hybrid lattice-plasmons in layered cuprates
Ke-Jun Xu, Nathan Giles-Donovan, Stefano Agrestini +11
Metallic systems with delocalized valence electrons host collective charge density oscillations known as plasmons. On the other hand, conventional insulators do not have free elect…
Non-local low energy neutral excitations in a strongly disordered triangular Mott magnet CrSeBr
Wenhao Liu, Dechen Zhang, Yuanqi Lyu +13
Understanding if low-energy excitations can remain itinerant in the presence of strong disorder remains a central challenge in frustrated quantum magnets, where disorder is general…
Weak phonon coupling to nematic quantum critical mode in
S. Wu, D. Ishikawa, A. Q. R. Baron +9
In this work, we investigate the softening of the in-plane transverse acoustic phonon driven by electronic nematicity in BaFe(AsP) using inelastic X-ray scatter…
