Realization of Non-Hermitian Hopf Bundle Matter
Yung Kim, Hee Chul Park, Minwook Kyung +6
Line excitations in topological phases are a subject of particular interest because their mutual linking structures encode robust topological information of matter. It has been rec…
Comment on "Amplified emission and lasing in photonic time crystals"
Jagang Park, Hee Chul Park, Kyungmin Lee +5
Lyubarov et al. (Research Articles, 22 July 2022, p. 425) claim that the spontaneous emission rate of an atom vanishes at the momentum gap edges of photonic Floquet media. We show…
Triangular lattice Hubbard model physics at intermediate temperatures
Kyungmin Lee, Prakash Sharma, Oskar Vafek +1
Moire systems offer an exciting playground to study many-body effects of strongly correlated electrons in regimes that are not easily accessible in conventional material settings.…
Multimagnon dynamics and thermalization in the easy-axis ferromagnetic chain
Prakash Sharma, Kyungmin Lee, Hitesh J. Changlani
Quasiparticles are physically motivated mathematical constructs for simplifying the seemingly complicated many-body description of solids. A complete understanding of their dynamic…
Frustration-induced emergent Hilbert space fragmentation
Kyungmin Lee, Arijeet Pal, Hitesh J. Changlani
Although most quantum systems thermalize locally on short time scales independent of initial conditions, recent developments have shown this is not always the case. Lattice geometr…
Exact three-colored quantum scars from geometric frustration
Kyungmin Lee, Ronald Melendrez, Arijeet Pal +1
Non-equilibrium properties of quantum materials present many intriguing properties, among them athermal behavior, which violates the eigenstate thermalization hypothesis. Such beha…
Spin motive force induced by Rashba interaction in the strong sd coupling regime
Gen Tatara, Noriyuki Nakabayashi, Kyun-Jin Lee
Spin motive force induced by the Rashba interaction in the presence of strong sd interaction between conduction electron and localized spin is theoretically studied. The motive for…
