Proof of nonintegrability of the spin- bilinear-biquadratic chain model
HaRu K. Park, SungBin Lee
Spin- chain models have been extensively studied in condensed matter physics, significantly advancing our understanding of quantum magnetism and low-dimensional systems, which e…
Controllable Skyrmion Islands in a Moiré Magnet
Jemin Park, HaRu K. Park, SungBin Lee
Antiferromagnetic(AFM) skyrmions have been in the spotlight as ideal topological magnetic bits. Although they are topologically protected, they do not exhibit the skyrmion Hall eff…
Graph theoretical proof of nonintegrability in quantum many-body systems : Application to the PXP model
HaRu K. Park, SungBin Lee
A rigorous proof of integrability or non-integrability in quantum many-body systems is among the most challenging tasks, as it involves demonstrating the presence or absence of loc…
Subharmonic fidelity revival in a driven PXP model
HaRu K. Park, SungBin Lee
The PXP model hosts a special set of nonergodic states, referred to as quantum many-body scars. One of the consequences of quantum scarring is the periodic revival of the wave func…
Controllable Floquet edge modes in a multi-frequency driving system
HaRu K. Park, Junmo Jeon, Gil Young Cho +1
A driven quantum system has been recently studied in the context of nonequilibrium phase transitions and their responses. In particular, for a periodically driven system, its dynam…
