Change in charge density wave order beyond the Lifshitz transition in 2H-Ta\textsubscript{1 $\pm I^´$ }S\textsubscript{2}

Mihir Date, Jan Berges, Enrico Da Como +6

We investigate electronic instabilities in 2H-TaS\textsubscript{2} and a self-intercalated variant, 2H $^{†}$ -Ta\textsubscript{1+ $I^´$ }S\textsubscript{2}. In conventional samples…

Interplay of Kondo Physics with Incommensurate Charge Density Waves in CeTe $_{3}$

Aymeric Saunot, Vesna Miksic Trontl, Ilya I. Klimovskikh +9

CeTe $_{3}$ is a 2--dimensional (2D) Van der Waals (VdW) material with incommensurate charge density waves (CDW), extremely high transition temperature ( $T_{C D W}$ ) and a large momentu…

Vector spin polarization evolution determined in an entangled muon-fluorine system under pulsed excitation

Dipranjan Chatterjee, Benjamin M. Huddart, Hank C. H. Wu +4

A spin-polarized muon implanted into a fluoride forms a coupled F-- $I^¼$ --F complex in which the muon spin and neighbouring fluorine nuclear spins become entangled. Here we apply ra…

Chiral charge density wave in 4Hb- and 1T-TaS $_{2}$ : The Role of interlayer coupling

Roni Anna Gofman, Abigail Dishi, Hyeonhu Bae +12

We use micro-angle-resolved photoemission spectroscopy (micro-ARPES) to investigate chiral charge density waves (CDWs) in 4Hb-TaS $_{2}$ with micron-scale spatial resolution. In the 1…

Charge transfer empties the flat band in 4H $_{b}$ -TaS $_{2}$ -- except at the surface

Mihir Date, Hyeonhu Bae, Alex Louat +5

The 4H\textsubscript{b} polytype of TaS $_{2}$ is a natural heterostructure of H and T-type layers. Intriguing recent evidence points towards a possibly chiral superconducting ground…

Emergence of a Fermi-surface in the current-driven Hidden state of 1T-TaS $_{2}$

Yuval Nitzav, Roni Gofman, Ilay Mangel +9

The origin of the insulating state in 1T-TaS $_{2}$ has long been a subject of debate. A short current pulse transforms this insulating state into a metastable metallic phase. Using m…
