Two-color laser control of photocurrent and high harmonics in graphene
Minoru Kanega, Masahiro Sato
We comprehensively investigate two-color-laser-driven photocurrent and high harmonic generation (HHG) in graphene models. By numerically solving the quantum master equation, we uni…

Signature of BKT-like spin transport in a quasi-2D antiferromagnet BaNiVO
Kurea Nakagawa, Minoru Kanega, Tomoyuki Yokouchi +2
In two-dimensional (2D) spin systems, the augmentation of spin fluctuations gives rise to quasi-long-range order; however, how they manifest in spin transport remains unclear. Here…

Triplons, triplon pairs and dynamical symmetries in laser-driven Shastry-Sutherland magnets
Mina Udono, Masahiro Sato
In frustrated magnets, a variety of novel phenomena arise due to their peculiar magnetic states, whose excitations usually reside in the GHz to THz range. Intense THz lasers, there…
