Pole-skipping without master variable and holographic superfluids
Makoto Natsuume, Takashi Okamura
The pole-skipping is a universal property of Green's functions at strong coupling found by the AdS/CFT duality. There is a conventional formalism of the pole-skipping, but it relie…
Pole-skipping as missing states
Makoto Natsuume, Takashi Okamura
It remains unclear in general how the pole-skipping appears as a physical phenomenon, and we study the issue in the context of the AdS soliton. The pole-skipping has been discussed…
Pole-skipping in a non-black-hole geometry
Makoto Natsuume, Takashi Okamura
The pole-skipping has been discussed in black hole backgrounds, but we point out that the pole-skipping exists even in a non-black-hole background, the AdS soliton. For black holes…
Semiclassical Einstein equations from holography and boundary dynamics
Akihiro Ishibashi, Kengo Maeda, Takashi Okamura
In this paper, we consider how to formulate semiclassical problems in the context of the AdS/CFT correspondence, based on the proposal of Compere and Marolf. Our prescription invol…
Holographic Meissner Effect
Makoto Natsuume, Takashi Okamura
The holographic superconductor is the holographic dual of superconductivity, but there is no Meissner effect in the standard holographic superconductor. This is because the boundar…
Nonuniqueness of scattering amplitudes at special points
Makoto Natsuume, Takashi Okamura
We point out little discussed phenomenon in elementary quantum mechanics. In one-dimensional potential scattering problems, the scattering amplitudes are not uniquely determined at…
