Local multiplet formation around a single vacancy in graphene: an effective Anderson model analysis based on the block-Lanczos DMRG method
Tomonori Shirakawa, Seiji Yunoki
To better understand the electronic structure of a single vacancy in graphene, we study the ground state property of an effective Anderson model, consisting of three dangling $sp^2…
Proximate Kitaev system for an intermediate magnetic phase in in-plane magnetic fields
Beom Hyun Kim, Shigetoshi Sota, Tomonori Shirakawa +2
Motivated by the magnetic phase transition of a proximate Kitaev system -RuCl in the presence of a magnetic field, we study the simplest but essential quantum spin model wit…
Photoinduced pairing in the Kondo lattice model
Tomonori Shirakawa, Shohei Miyakoshi, Seiji Yunoki
The previous theoretical study has shown that pulse irradiation to the Mott insulating state in the Hubbard model can induce the enhancement of superconducting correlation due to t…
Block-Lanczos density-matrix renormalization-group approach to spin transport in Heisenberg chains coupled to leads
F. Lange, S. Ejima, T. Shirakawa +2
We adapt the block-Lanczos density-matrix renormalization-group technique to study the spin transport in a spin chain coupled to two non-interacting fermionic leads. As an example,…
Topological property of a system with a honeycomb lattice structure
Beom Hyun Kim, Kazuhiro Seki, Tomonori Shirakawa +1
A system with a honeycomb lattice structure such as NaIrO was firstly proposed as a topological insulator even though NaIrO and its isostructural materia…
Photoinduced Pairing in the Hubbard Model
Tatsuya Kaneko, Tomonori Shirakawa, Sandro Sorella +1
By employing unbiased numerical methods, we show that pulse irradiation can induce unconventional superconductivity even in the Mott insulator of the Hubbard model. The superconduc…
