Photoinduced Phase Transition in Two-Band model on Penrose Tiling
Ken Inayoshi, Yuta Murakami, Akihisa Koga
We study the effects of the photo irradiation on the band insulating state in the two-band Hubbard model on the Penrose tiling. Examining the time- and site-dependent physical quan…
Unveiling the underlying interactions in Ta2NiSe5 from photo-induced lifetime change
Denis Golez, Sydney K. Y. Dufresne, Min-Jae Kim +14
We present a generic procedure for quantifying the interplay of electronic and lattice degrees of freedom in photo-doped insulators through a comparative analysis of theoretical ma…
Photo-induced Dynamics of Quasicrystalline Excitonic Insulator
Ken Inayoshi, Yuta Murakami, Akihisa Koga
We study the photo-induced dynamics of the excitonic insulator in the two-band Hubbard model on the Penrose tiling by means of the time-dependent real-space mean-field approximatio…
Light-induced hidden odd-frequency order in a model for AC
Philipp Werner, Yuta Murakami
Laser driving in systems with competing or coupled electronic orders can lead to the enhancement of orders, or even to the appearance of hidden phases without an equilibrium analog…
Role of Majorana fermions in spin transport of anisotropic Kitaev model
Hirokazu Taguchi, Yuta Murakami, Akihisa Koga +1
We study a quantum spin Kitaev model with zigzag edges to clarify the effects of anisotropy in the exchange couplings on the spin propagation. We simulate the spin and Majorana dyn…
Exploring nonequilibrium phases of photo-doped Mott insulators with Generalized Gibbs ensembles
Yuta Murakami, Shintaro Takayoshi, Tatsuya Kaneko +4
Photo-excited strongly correlated systems can exhibit intriguing non-thermal phases, but the theoretical investigation of them poses significant challenges. In this work, we introd…
Majorana correlations in the Kitaev model with ordered-flux structures
Akihisa Koga, Yuta Murakami, Joji Nasu
We study the effects of the flux configurations on the emergent Majorana fermions in the Kitaev model on a honeycomb lattice, where quantum spins are fractionalized into it…
Photo-induced phase transition and associated time scales in the excitonic insulator TaNiSe
Tanusree Saha, Denis Golez, Giovanni De Ninno +5
We investigate the non-equilibrium electronic structure and characteristic time scales in a candidate excitonic insulator, TaNiSe, using time- and angle-resolved photoemiss…
Gauge invariance of light-matter interactions in first-principle tight-binding models
Michael Schüler, Jacob A. Marks, Yuta Murakami +2
We study the different ways of introducing light-matter interaction in first-principle tight-binding (TB) models. The standard way of describing optical properties is the velocity…
