Hybridization-gap Formation and Superconductivity in the Pressure-induced Semimetallic Phase of the Excitonic Insulator TaNiSe
Kazuyuki Matsubayashi, Hidekazu Okamura, Takashi Mizokawa +19
The excitonic insulator TaNiSe experiences a first-order structural transition under pressure from rippled to flat layer-structure at Ps = 3 GPa, which drives the system fr…
The spontaneous symmetry breaking in TaNiSe is structural in nature
Edoardo Baldini, Alfred Zong, Dongsung Choi +16
The excitonic insulator is an electronically-driven phase of matter that emerges upon the spontaneous formation and Bose condensation of excitons. Detecting this exotic order in ca…
Detecting electron-phonon couplings during photo-induced phase transition
Takeshi Suzuki, Yasushi Shinohara, Yangfan Lu +13
Photo-induced phase transitions have been intensively studied owing to the ability to control a material of interest in the ultrafast manner, which can induce exotic phases unable…
Photo-excited Dynamics in the Excitonic Insulator Ta2NiSe5
Daniel Werdehausen, Tomohiro Takayama, Gelon Albrecht +3
The excitonic insulator is an intriguing correlated electron phase formed of condensed excitons. A promising candidate is the small band gap semiconductor Ta2NiSe5. Here we investi…
Coherent Order Parameter Oscillations in the Ground State of the Excitonic Insulator Ta2NiSe5
Daniel Werdehausen, Tomohiro Takayama, Marc Höppner +6
The excitonic insulator is an intriguing electronic phase of quasi-condensed excitons. A prominent candidate is the small bandgap semiconductor Ta2NiSe5, in which excitons are beli…
