Chern-Simons type cross-correlations and geometric Born effective charge of phonons
Swati Chaudhary, Takashi Oka
The interplay between different degrees of freedom in condensed matter systems engenders a rich variety of emergent phenomena. In particular, fermions with non-trivial quantum geom…
Semi-Analytical Engineering of Strongly Driven Nonlinear Systems Beyond Floquet and Perturbation Theory
Kento Taniguchi, Atsushi Noguchi, Takashi Oka
Strongly driven nonlinear systems are frequently encountered in physics, yet their accurate control is generally challenging due to the intricate dynamics. In this work, we present…
Shockwave-Enhanced Floquet Engineering in Relativistic Quasiparticles
Takashi Oka
We investigate Floquet engineering of three-dimensional Dirac fermions driven by propagating waves, identifying distinct quantum states and phase transitions in the time-like, ligh…
Tunneling Breakdown of a Strongly Correlated Insulating State in VO Induced by Intense Multi-Terahertz Excitation
B. Mayer, C. Schmidt, A. Grupp +8
We directly trace the near- and mid-infrared transmission change of a VO thin film during an ultrafast insulator-to-metal transition triggered by high-field multi-terahertz tra…
