研究室紹介
Professor Sam-hyun Lee's research lab specializes in experimental and theoretical particle physics, with a focus on exploring new physics beyond the Standard Model using novel collider concepts such as the $e\mu$ collider. The lab also investigates acoustic metamaterials and topological wave phenomena, particularly resonant states at interfaces with exotic effective properties like negative mass density and modulus. Their work combines fundamental particle physics with advanced materials science, aiming to uncover lepton-number-violating processes and exotic wave behaviors in structured media. The lab emphasizes interdisciplinary research at the intersection of high-energy physics and condensed matter physics.

3We study the potential impacts of a new type of particle collider---an $e\ensuremath{\mu}$ collider---on the search for new physics beyond the standard model. As our first attempt for exploring its physics potential, we demonstrate that the $e\ensuremath{\mu}$ collision experiment can be highly efficient in searching for lepton-number-violating flavor-changing neutral current phenomena.
We observed resonant states on the interface between the acoustic metamaterials of negative effective mass density and negative effective modulus, which were based on membranes and side holes, respectively. All resonances excited by placing the driving pressure at different places have the same spatial pressure distribution and resonance frequency. The amplitude decayed exponentially on both sides of the interface. We present experimental results on the spatial and the spectral characteristics o
