Ultrasound Evidence for a Low-Temperature Anomaly Inside the Superconducting State of 4Hb-TaS
Yongwei Li, Dmitri V. Efremov, Paul Leask +7
We report low-temperature ultrasound measurements on single crystals of the layered van der Waals superconductor 4Hb-TaS. Specific heat and ac magnetic susceptibility show a sh…
Unconventional Superconductivity in the Chiral Topological Semimetal Ag2Pd3S
Roshan Kumar Kushwaha, Dibyendu Samanta, Sudarshan Sharma +15
Chiral crystals provide a unique setting where broken inversion symmetry, strong spin-orbit coupling, and electronic topology intertwine, yet superconductivity in intrinsically chi…
Competing incommensurability, electronic correlations, and superconductivity in a hybrid transition metal dichalcogenide
Jean C. Souza, Moshe Haim, Lorenzo Crippa +8
The engineering of superlattices in two-dimensional van der Waals materials has enabled the realization of rich phase diagrams hosting topological and strongly correlated phases. W…
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…
Microscopic evidence of dominant excitonic instability in Ta2NiSe5
Seokjin Bae, Arjun Raghavan, Irena Feldman +2
An excitonic insulator (EI) is a charge-neutral bosonic condensate of spontaneously formed electron-hole pairs. Exotic quantum phenomena such as dissipationless charge neutral tran…
Light-induced trion-exciton competition revealed by ultrafast photoemission
Ittai Sidilkover, Nir Hen Levin, Yuval Nitzav +11
Strong Coulomb interactions in low-dimensional quantum materials give rise to emergent bound states such as excitons and trions. Trions are conventionally secondary excitations, re…
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…
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…
Ising superconductivity in the bulk incommensurate layered material (PbS)(TaS)
Sajilesh K. P., Roni Anna Gofman, Yuval Nitzav +8
Exploiting the spin-valley degree of freedom of electrons in materials is a promising avenue for energy-efficient information storage and quantum computing. A key challenge in util…
Ramp reversal memory in bulk crystals of 1T-TaS2
Avital Fried, Ouriel Gotesdyner, Irena Feldman +2
The ramp reversal memory (RRM) is a non-volatile memory effect previously observed in correlated oxides exhibiting temperature-driven metal-insulator transitions (MITs). In essence…
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…
Charge transfer and Spin-Valley locking in 4Hb-TaS
Avior Almoalem, Roni Gofman, Yuval Nitzav +12
4Hb-TaS is a superconductor that exhibits unique characteristics such as time-reversal symmetry breaking, hidden magnetic memory, and topological edge modes. It is a naturally…
Critical charge fluctuations and emergent coherence in a strongly correlated excitonic insulator
Pavel A. Volkov, Mai Ye, Himanshu Lohani +3
Excitonic insulator is a coherent electronic phase that results from the formation of a macroscopic population of bound particle-hole pairs - excitons. With only a few candidate ma…
