Infrared Divergences as Itinerant Vacua
Masahiro Morikawa
Infrared divergences (IRDs) are usually treated as pathologies to be cancelled, regularized, or hidden in dressed asymptotic states. This paper develops a complementary and constru…
Seismic 1/f Fluctuations from Amplitude Modulated Earth's Free Oscillation
Akika Nakamichi, Manaya Matsui, Masahiro Morikawa
We first report that the seismic time-sequence data from around the world, excluding major earthquakes, consistently yield the power spectral density inversely proportional to the…
A simple model for pink noise from amplitude modulations
Masahiro Morikawa, Akika Nakamichi
We propose a simple model for the origin of pink noise (or 1/f fluctuation) based on the beat of cooperative waves. These cooperative waves arise spontaneously in a system with syn…
Supermassive Black Holes from Bose-Einstein Condensed Dark Matter -- or Black and Dark Separation by Angular Momentum
Masahiro Morikawa
Many supermassive black holes (SMBH) of mass are observed at the center of each galaxy even in the high redshift () Universe. To explain the early…
Low-Frequency Characterization of Music Sounds -- Ultra-Bass Richness from the Sound Wave Beats
Masahiro Morikawa
The orchestra performance is full of sublime rich sounds. In particular, the unison of violins sounds different from the solo violin. We try to clarify this difference and similari…
Planetary System from the Outer Edge of the Inner Void -- Classes and Populations of Variety
Masahiro Morikawa, Suzuka Amaya
Planets are common objects in the Universe, observationally as well as theoretically. However, the standard theory of their formation encounters many difficulties, such as dust fal…
