• Authors: Hiroki Kanda, Masahide Sato, Yu-ki Suzuki, Tadashi Takayanagi and Zixia Wei
• Abstract summary: We study the dynamics of end-of-the-world (EOW) branes in AdS with scalar fields localized on the branes. This allows us to construct explicit solutions dual to boundary RG flows. We also obtain a variety of annulus-like or cone-like shaped EOW branes, which are not possible without the scalar field.

• Abstract: In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds with boundaries. This allows us to construct explicit solutions dual to boundary RG flows. We also obtain a variety of annulus-like or cone-like shaped EOW branes, which are not possible without the scalar field. We also present a gravity dual of a CFT on a strip with two different boundary conditions due to the scalar potential, where we find the confinement/deconfinement-like transition as a function of temperature and the scalar potential. Finally, we point out that this phase transition is closely related to the measurement-induced phase transition, via a Wick rotation.

The interplay between the inherent twisted d-wave nature of the order parameter and the external magnetic flux enables the implementation of different artificial atoms.

  We consider deformations of boundary conditions in flat spacetimes under flat space co-dimension-two holographies, celestial holography and Wedge-like holography. In the former celestial-holographic approach, we imposed boundary conditions on initial and final bulk states in the scattering. In the latter Wedge-like holography, we consider mixed Neumann/Dirichlet boundary conditions on the null infinity of the light-cone.

We observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.

In the first model, we observe that the competition between the bulk X and Z measurements can lead to an entanglement phase transition. We give an interpretation of this transition in terms of random bond Ising model in a similar shallow circuit composed of random Haar gates.

  For wormholes connecting two spacelike regions in gravitational spacetimes, we find that the non-exactness is linked to a variable appearing in the phase space of the boundary CFT. We classify Berry phases in holographic CFTs based on the type of dual bulk diffeomorphism involved. We find that the Berry curvature, given by the Crofton form, characterizes the topological transition of the entanglement entropy in presence of a black hole.

  We study an open Heisenberg XXZ spin chain with long-range Ising-type interaction. We find that the chain lengths for this transition are increasing with decreasing range of the Ising-type interactions between distant spins. The transition can be explained by the suppression of ferromagnetic domains at the edges of the chain.
