Wasserstein Space of Quantum Chaos
Koji Hashimoto, Norihiro Tanahashi, Kentaroh Yoshida
We find that the effective dimension of the Wasserstein space of energy eigenstates decreases as a quantum system becomes more chaotic. To demonstrate this, we study a quantum coup…

Resonances in Lifetimes of AdS Oscillon
Takaki Matsumoto, Kanta Nakano, Ryosuke Suda +1
Oscillons are classical oscillatory solutions with very long but finite lifetimes in real scalar field theories with appropriate potentials. An interesting feature is that resonanc…

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…
