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…
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…
Hall anomaly and vortex charge in BiSrCaCuO
Yuval Nitzav, Amit Kanigel
We present a systematic study of the Hall conductance in BiSrCaCuO (Bi2212) thin films over a large range of doping. We find that in a large part of the phase diagr…
Link between superconductivity and a Lifshitz transition in intercalated BiSe
A. Almoalem, I. Silber, S. Sandik +12
Topological superconductivity is an exotic phase of matter in which the fully gapped superconducting bulk hosts gapless Majorana surface states protected by topology. Intercalation…
Observation of Josephson-like tunneling junction characteristics and positive magnetoresistance in Oxygen deficient Nickelate films of
Gad Koren, Anna Eyal, Leonid Iomin +1
Nickelate films have recently attracted broad attention due to the observation of superconductivity in the infinite layer phase of (obtained by reducing Sr…
Band inversion and topology of the bulk electronic structure in FeSeTe
Himanshu Lohani, Tamaghna Hazra, Amit Ribak +5
FeSeTe (FeSeTe) has recently emerged as a promising candidate to host topological superconductivity, with a Dirac surface state and signatures of Majorana bou…
