Excitations across the equilibrium and photoinduced `hidden' states of magnetoresistive manganites
Shiyu Fan, Feng Jin, Taehun Kim +16
"Hidden" phases, generated using ultrafast laser pulses (few hundred femtoseconds), with properties distinct from thermodynamic equilibrium, are appealing for technologies because…
Magnetoplasmons in -layer structures
Jinu Park, Taehun Kim, E. H. Hwang +1
We provide a systematic framework to investigate the magnetoplasmons of multilayer two-dimensional electron systems by using the Kac--Murdock--Szegő (KMS) Toeplitz matrix to consid…
Gapped out-of-phase plasmon modes in alternating-twist multilayer graphene
Taehun Kim, Hongki Min
We theoretically investigate the plasmon modes of alternating-twist multilayer graphene. In multilayer systems, interlayer coupling gives rise to distinctive plasmon modes, but cal…
Photoinduced dc Hall current in few-layer black phosphorus with a gate-tunable Floquet gap
Taehun Kim, Hansol Kim, Dongeun Kim +1
We theoretically explore Floquet engineering in few-layer black phosphorus (fBP) under time-periodic driving. Motivated by the ability of circularly polarized light to induce nontr…
Plasmons in N-layer systems
Taehun Kim, E. H. Hwang, Hongki Min
In multilayer structures, the coupling between layers gives rise to unique plasmon modes, but analytic solutions are typically available only for bilayers due to the increasing com…
