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…
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…
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…
