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…
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…
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…
Chiral to Nematic Crossover in the Superconducting State of 4Hb-TaS
I. Silber, S. Mathimalar, I. Mangel +10
Most superconductors have an isotropic, single component order parameter, and are well described by the BCS theory for superconductivity. Unconventional, multiple components superc…
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…
Failed excitonic quantum phase transition in TaNi(SeS)
Pavel A. Volkov, Mai Ye, Himanshu Lohani +3
We study the electronic phase diagram of the excitonic insulator candidates TaNi(SeS) [x=0, ... ,1] using Raman spectroscopy. Critical excitonic fluctuations ar…
Lattice dynamics of the excitonic insulator TaNi(SeS)
Mai Ye, Pavel A. Volkov, Himanshu Lohani +4
Recently, we employed electronic polarization-resolved Raman spectroscopy to reveal the strongly correlated excitonic insulator (EI) nature of Ta2NiSe5, Volkov et al. [arXiv:2007.0…
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…
Superconductivity and phonon self-energy effects in FeTeSe
S. -F. Wu, A. Almoalem, I. Feldman +3
We study FeTeSe multi-band superconductor with K by polarization-resolved Raman spectroscopy. Deep in the superconducting state, we detect pair-brea…
