Kaluza-Klein monopole with scalar multiplet hair
Takaaki Ishii, Keiju Murata, Keita Sugawara
We construct Kaluza-Klein monopole solutions with scalar hair provied by a massive complex scalar field multiplet that minimally couples to five-dimensional Einstein gravity. Writi…
Oscillons in AdS space
Takaaki Ishii, Takaki Matsumoto, Kanta Nakano +2
We study oscillons in a real scalar field theory in a (3+1)-dimensional AdS space with global coordinates. The initial configuration is given by a Gaussian shape with an appropriat…
Convexity restoration from hairy black hole in Einstein-Maxwell-charged scalar system in AdS
Takaaki Ishii, Yu Nakayama
In the Einstein-Maxwell-charged scalar system with a negative cosmological constant in arbitrary dimensions higher than three, there exists a horizonless charged soliton solution,…
Boundary driven turbulence on string worldsheet
Takaaki Ishii, Keiju Murata, Kentaroh Yoshida
We study the origin of turbulence on the string worldsheet with boundaries laid in anti de Sitter (AdS) spacetime. While the classical motion of a single closed string in AdS is in…
Turbulence on open string worldsheets under non-integrable boundary conditions
Takaaki Ishii, Ryo Kitaku, Keiju Murata +1
We demonstrate the turbulent dynamics of the Nambu-Goto open string in the AdS3 spacetime. While the motion of a classical closed string in AdS is known to be integrable, the integ…
