Sang Won Seo 교수의 연구실은 신경과학과 초유체 물리학을 융합한 독특한 연구 분야를 선도하고 있습니다. 주로 노화 관련 인지 기능 저하와 관련된 뇌 질환, 특히 정신행동성 지능 저하(FTD/FTLD) 및 비정형 알츠하이머병의 뇌 구조적 변화를 분석하며, 특히 전두엽 및 편측 피각의 손상이 인지 기능 저하와 어떻게 연관되는지 규명하고 있습니다. 동시에 초저온 물리학 분야에서 원자 보즈-아인슈타인 응축체를 이용한 양자 풍성과 반도체 구조에서의 반정수 스핀 비틀림(반자기성 스핀 보존) 현상 등 양자물리적 메커니즘의 실험적 규명에도 기여하고 있습니다.

NAFLD was independently associated with lower cognitive performance independent of CVD and its risk factors. Given the scarcity of risk factors associated with age-related cognitive decline, these findings may have significant implications.
Our findings suggest the presence of hierarchy between svMCI and SVaD, and that the cognitive decline from svMCI to SVaD is associated with lesions in dorsolateral prefrontal and temporal cortices.
We report on the observation of half-quantum vortices (HQVs) in the easy-plane polar phase of an antiferromagnetic spinor Bose-Einstein condensate. Using in situ magnetization-sensitive imaging, we observe that pairs of HQVs with opposite core magnetization are generated when singly charged quantum vortices are injected into the condensate. The dynamics of HQV pair formation is characterized by measuring the temporal evolutions of the pair separation distance and the core magnetization, which re
In a two-dimensional (2D) classical fluid, a large-scale flow structure emerges out of turbulence, which is known as the inverse energy cascade where energy flows from small to large length scales. An interesting question is whether this phenomenon can occur in a superfluid, which is inviscid and irrotational by nature. Atomic Bose-Einstein condensates (BECs) of highly oblate geometry provide an experimental venue for studying 2D superfluid turbulence, but their full investigation has been hinde
Patients with FTD and FTLD often develop symptoms after age 65, and age at onset represents an important consideration when making antemortem neuropathologic predictions.
Our findings suggest that the protective effects of education against cognitive decline remain in early-stage aMCI and disappear in late-stage aMCI.
We present an experimental study on the interaction and dynamics of half-quantum vortices (HQVs) in an antiferromagnetic spinor Bose-Einstein condensate. By exploiting the orbit motion of a vortex dipole in a trapped condensate, we perform a collision experiment of two HQV pairs, and observe that the scattering motions of the HQVs is consistent with the short-range vortex interaction that arises from nonsingular magnetized vortex cores. We also investigate the relaxation dynamics of turbulent co
