Modular chaos, operator algebras, and the Berry phase
Jan de Boer, Bahman Najian, Jeremy van der Heijden +1
Modular Berry transport associates a geometric phase to a zero mode ambiguity in a family of modular operators. In holographic settings, this phase was shown to encode nontrivial i…
Changing states in holography: From modular Berry curvature to the bulk symplectic form
Bartlomiej Czech, Jan de Boer, Ricardo Espíndola +3
We present a new perspective on bulk reconstruction using Berry phases in the boundary CFT. Our parallel transport of modular Hamiltonians is associated to a trajectory in the spac…
Islands in FRW Cosmologies
Ricardo Espíndola, Bahman Najian, Dora Nikolakopoulou
We search for candidate island regions in FRW cosmologies supported by radiation, cosmological constant , and non-zero spatial curvature. The radiation is assumed to be in a the…
Virasoro Entanglement Berry Phases
Jan de Boer, Ricardo Espíndola, Bahman Najian +3
We study the parallel transport of modular Hamiltonians encoding entanglement properties of a state. In the case of 2d CFT, we consider a change of state through action with a suit…
