Thermal transport and low-temperature specific heat in 4Hb-TaS
M. Gillig, I. Mangel, I. Feldman +4
We investigate the low-energy excitation spectrum of the van der Waals heterostructure superconductor 4Hb-TaS using ultra-low-temperature specific-heat and thermal-conductivity…
Trion gas on the surface of a failed excitonic insulator
Yuval Nitzav, Abigail Dishi, Himanshu Lohani +15
Trions, three-body bound states composed of an exciton and an additional charge, are typically fragile and require external excitation to form. Here, we report the spontaneous emer…
Flux-tunable transmon incorporating a van der Waals superconductor via an Al/AlO/4Hb-TaS Josephson junction
Eliya Blumenthal, Ilay Mangel, Amit Kanigel +1
Incorporating van der Waals (vdW) superconductors into Josephson elements extends circuit-QED beyond conventional Al/AlO/Al tunnel junctions and enables microwave probes of unc…
Mixed Triplet-Singlet Order Parameter in Decoupled Superconducting 1H Monolayers of Transition-Metal Dichalcogenides
Avior Almoalem, Sajilesh Kunhiparambath, Roni Anna Gofman +9
Understanding the emergence of unconventional superconductivity, where the order parameter deviates from simple isotropic s-wave pairing, is a central puzzle in condensed matter ph…
Chiral charge density wave in 4Hb- and 1T-TaS: 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 with micron-scale spatial resolution. In the 1…
Emergence of a Fermi-surface in the current-driven Hidden state of 1T-TaS
Yuval Nitzav, Roni Gofman, Ilay Mangel +9
The origin of the insulating state in 1T-TaS has long been a subject of debate. A short current pulse transforms this insulating state into a metastable metallic phase. Using m…
