Kondo Screening of Local Moments in a Triangular Triple Quantum Dot Connected to Normal and Superconducting Leads
Masashi Hashimoto, Yoshimichi Teratani, Masaya Shirotani +5
We study the interplay between the Kondo and superconducting (SC) proximity effects, taking place in a triangular triple quantum dot (TTQD) connected to one normal and two SC leads…
Unusual band evolution and persistence of topological surface states in high-T_C magnetic topological insulator
K. Hori, S. Souma, C. -W. Chuang +12
Understanding the mechanism of ferromagnetism in ferromagnetic topological insulators (TIs) is a key to realize exotic time-reversal-symmetry-broken quantum phases. However, electr…
Robust charge-density wave strengthened by electron correlations in monolayer 1T-TaSe2 and 1T-NbSe2
Yuki Nakata, Katsuaki Sugawara, Ashish Chainani +11
Combination of low-dimensionality and electron correlation is vital for exotic quantum phenomena such as the Mott-insulating phase and high-temperature superconductivity. Transitio…
Observation of inverted band structure in topological Dirac-semimetal candidate CaAuAs
Kosuke Nakayama, Zhiwei Wang, Daichi Takane +13
We have performed high-resolution angle-resolved photoemission spectroscopy of ternary pnictide CaAuAs which is predicted to be a three-dimensional topological Dirac semimetal (TDS…
Dimensionality reduction and band quantization induced by potassium intercalation in 1-HfTe
Y. Nakata, K. Sugawara, A. Chainani +9
We have performed angle-resolved photoemission spectroscopy on transition-metal dichalcogenide 1-HfTe to elucidate the evolution of electronic states upon potassium (K) depo…
Monolayer VTe2: Incommensurate Fermi surface nesting and suppression of charge density waves
Katsuaki Sugawara, Yuki Nakata, Kazuki Fujii +4
We investigated the electronic structure of monolayer VTe2 grown on bilayer graphene by angle-resolved photoemission spectroscopy (ARPES). We found that monolayer VTe2 takes the oc…
Pseudogap, Fermi arc, and Peierls-insulating phase induced by 3D-2D crossover in monolayer VSe2
Yuki Umemoto, Katsuaki Sugawara, Yuki Nakata +2
One of important challenges in condensed-matter physics is to realize new quantum states of matter by manipulating the dimensionality of materials, as represented by the discovery…

Takafumi Sato, Zhiwei Wang, Kosuke Nakayama +8
We have performed angle-resolved photoemission spectroscopy of layered ternary telluride Ta3SiTe6 which is predicted to host nodal lines associated with nonsymmorphic crystal symme…
Observation of Chiral Fermions with a Large Topological Charge and and Associated Fermi-Arc Surface States in CoSi
Daichi Takane, Zhiwei Wang, Seigo Souma +12
Topological semimetals materialize a new state of quantum matter where massless fermions protected by a specific crystal symmetry host exotic quantum phenomena. Distinct from well-…
