Direct Evidence of Unconventional Superconductivity in Doped Kagome system RVSb
Avior Almoalem, Yuqing Xing, Iksu Jang +7
The superconducting pairing symmetry of kagome metals remains a central unresolved question largely because phase-sensitive experiments capable of distinguishing between different…
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…
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…
Discovery of a 1D edge mode in a Magnetic Topological semimetal
Avior Almoalem, Rebecca Chan, Brinda Kuthanazhi +6
In rare-earth monopnictides like NdBi, the interplay between magnetism and topology results in an extremely unusual topological semimetal phase which simultaneously hosts Weyl poin…
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…
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…
Visualizing the melting of the charge density wave in UTe2 by generation of pairs of topological defects with opposite winding
Anuva Aishwarya, Julian May-Mann, Avior Almoalem +6
Topological defects are singularities in an ordered phase that can have a profound effect on phase transitions and serve as a window into the order parameter. In this work we use s…
First Order Quantum Phase Transition in the Hybrid Metal-Mott Insulator Transition Metal Dichalcogenide 4Hb-TaS2
Abhay Kumar Nayak, Aviram Steinbok, Yotam Roet +8
Coupling together distinct correlated and topologically non-trivial electronic phases of matter can potentially induce novel electronic orders and phase transitions among them. Tra…
Evidence of a two-component order parameter in 4Hb-TaS2 in the Little-Parks effect
Avior Almoalem, Irena Feldman, Michael Shlafman +5
Finding unambiguous evidence of non-trivial pairing states is one of the greatest experimental challenges in the field of unconventional superconductivity. Such evidence requires p…
Magnetic memory and spontaneous vortices in a van der Waals superconductor
Eylon Persky, Anders V. Bjørlig, Irena Feldman +7
Doped Mott insulators exhibit some of the most intriguing quantum phases of matter, including quantum spin-liquids, unconventional superconductors, and non-Fermi liquid metals. Suc…
Visualization of Topological Boundary Modes Manifesting Topological Nodal-Point Superconductivity
Abhay Kumar Nayak, Aviram Steinbok, Yotam Roet +10
The extension of the topological classification of band insulators to topological semimetals gave way to the topology classes of Dirac, Weyl, and nodal line semimetals with their u…
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…
