BCS superconductivity in the presence of wave dark matter
Yechan Kim, Hye-Sung Lee, Jiheon Lee +1
In the established era of dark matter, condensed matter Hamiltonians-including those of superconductors-may require extension to account for the surrounding Galactic environment. W…
Oscillating scalar potential and its implications for cosmic neutrino background searches
Yechan Kim, Hye-Sung Lee
We propose a novel mechanism in which an external oscillatory wave modulates the mass-squared term of a scalar potential, periodically switching its sign. As a result of this "pote…
Dark gauge-mediated supersymmetry breaking with a massless dark photon
Brian Batell, Yechan Kim, Hye-Sung Lee +1
We study dark gauge-mediated supersymmetry breaking (dark GMSB) in a theory with a new unbroken local symmetry and massless dark photon. Messenger fields charged under b…
Refined approaches in second leptogenesis for the baryon-lepton asymmetry discrepancy
YeolLin ChoeJo, Kazuki Enomoto, Yechan Kim +1
The temperature-dependent mass of the heavy neutrino can lead to the second leptogenesis occurring below the electroweak scale, potentially explaining the large discrepancy between…
Second leptogenesis: Unraveling the baryon-lepton asymmetry discrepancy
YeolLin ChoeJo, Kazuki Enomoto, Yechan Kim +1
We propose a novel scenario to explain the matter-antimatter asymmetry by twofold leptogenesis, wherein heavy Majorana neutrinos exhibit temperature-dependent masses and engage in…
Dirac-Majorana neutrino type oscillation induced by a wave dark matter
YeolLin ChoeJo, Yechan Kim, Hye-Sung Lee
Some properties of a neutrino may differ significantly depending on whether it is Dirac or Majorana type. The type is determined by the relative size of Dirac and Majorana masses,…
