Evidence of intertwined pair density and charge density wave orders in UTe2
Zhen Zhu, Yudi Huang, Julian May-Mann +9
The strongly correlated spin-triplet superconductor UTe2 hosts an unusual landscape of magnetic-field-sensitive charge density wave (CDW) phases, positioning it as a compelling sys…
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…
Topological surface states revealed by the Zeeman effect in superconducting UTe2
Zhen Zhu, Hans Christiansen, Yudi Huang +11
Intrinsic topological superconductors with protected boundary modes obeying non-Abelian statistics constitute a vanishingly small class of quantum materials. A defining spectroscop…
Dynamic competition between phason and amplitudon observed by ultrafast multimodal scanning tunneling microscopy
Seokjin Bae, Arjun Raghavan, Soyeun Kim +7
The intertwining between two ordered states that arise from the same interactions is reflected in the dynamics of their coupled collective excitations. While the equilibrium phase…
Visualizing the low-energy electronic structure of the triplet superconductor UTe through quasiparticle interference
Anuva Aishwarya, Hans Christiansen, Sheng Ran +6
The identification, control and theoretical modelling of spin-triplet superconductors (STC) remain a central theme in quantum materials research. Intrinsic STC are rare but offer r…
Axionic tunneling from a topological Kondo insulator
Saikat Banerjee, Anuva Aishwarya, Fei Liu +4
Discoveries over the past two decades have revealed the remarkable ability of quantum materials to emulate relativistic properties of the vacuum, from Dirac cones in graphene to th…
