Direct Observation of the Zigzag Edge States of a Supramolecular Diatomic Kagome Lattice
Ryohei Nemoto, Xiangzhi Meng, Behzad Mortezapour +11
Lattice geometry plays a fundamental role in the behavior of Bloch electrons in a crystal. The diatomic Kagome lattice, an extension of the honeycomb and Kagome lattices, is predic…
- and -wave quantum liquid crystal orders in cuprate superconductors, -(BEDT-TTF)X, and coupled chain Hubbard models: functional-renormalization-group analysis
Rina Tazai, Youichi Yamakawa, Masahisa Tsuchiizu +1
Unconventional symmetry breaking without spin order,such as the rotational symmetry breaking (=nematic or smectic) orders as well as the spontaneous loop-current orders, have been…
Householder transformed density matrix functional embedding theory
Sajanthan Sekaran, Masahisa Tsuchiizu, Matthieu Saubanère +1
Quantum embedding based on the (one-electron reduced) density matrix is revisited by means of the unitary Householder transformation. While being exact and equivalent to (but forma…
Prediction of pseudogap formation due to -wave bond-order in organic superconductor -(BEDT-TTF)X
Rina Tazai, Youichi Yamakawa, Masahisa Tsuchiizu +1
Rich hidden unconventional orders with pseudogap formation, such as the inter-site bond-order (BO), attract increasing attention in condensed matter physics. Here, we investigate t…
A molecular diamond lattice antiferromagnet as a Dirac semimetal candidate
Yasuhiro Shimizu, Akihiro Otsuka, Mitsuhiko Maesato +6
The ground state of a molecular diamond-lattice compound (ET)Ag(CN) is investigated by the magnetization and nuclear magnetic resonance spectroscopy. We found that the syst…
Competing Unconventional Charge-Density-Wave States in Cuprate Superconductors: Spin-Fluctuation-Driven Mechanism
Kouki Kawaguchi, Youichi Yamakawa, Masahisa Tsuchiizu +1
To understand the origin of unconventional charge-density-wave (CDW) states in cuprate superconductors, we establish the self-consistent CDW equation, and analyze the CDW instabili…
