Probing the axion-electron coupling at cavity experiments
Deog Ki Hong, Sang Hui Im, Jinsu Kim +2
Axion dark matter induces electromagnetic radiation in conductors through nearly perpetual oscillations of electrons, driven by axion-electron interactions through the so-called ch…
Planck isocurvature constraint on primordial black holes lighter than a kiloton
TaeHun Kim, Jinn-Ouk Gong, Donghui Jeong +3
We demonstrate that primordial black holes (PBHs) lighter than , which evaporated before the big bang nucleosynthesis, can induce significant isocurvature perturb…
Beyond the Mirror: Personal Analytics through Visual Juxtaposition with Other People's Data
Sungbok Shin, Sunghyo Chung, Hyeon Jeon +6
An individual's data can reveal facets of behavior and identity, but its interpretation is context dependent. We can easily identify various self-tracking applications that help pe…
Topotactic Reduction-Driven Crystal Field Excitations in Brownmillerite Manganite Thin Films
Feng Jin, Shiyu Fan, Mingqiang Gu +12
Topotactic reduction of perovskite oxides offers a powerful approach for discovering novel phenomena, such as superconducting infinite-layer nickelates and polar metallicity, and i…
Strict condition for the -wellposedness of fifth and sixth order dispersive equations
Taehun Kim
We provide a set of conditions that is necessary and sufficient for the -wellposedness of the Cauchy problem for fifth and sixth order variable-coefficient linear dispersive…
