Modular theory and symmetry resolution in hyperfinite von Neumann algebras
Giuseppe Di Giulio, Moritz Dorband, Johanna Erdmenger +1
We study modular theory in hyperfinite von Neumann algebras, i.e. in those of type II or type III, from the viewpoint of a subregion charge sector decomposition. We address this sy…
Brickwall, Normal Modes and Emerging Thermality
Souvik Banerjee, Suman Das, Moritz Dorband +1
In this article, we demonstrate how black hole quasi-normal modes can emerge from a Dirichlet brickwall model normal modes. We consider a probe scalar field in a BTZ geometry with…
Geometric Phases Characterise Operator Algebras and Missing Information
Souvik Banerjee, Moritz Dorband, Johanna Erdmenger +1
We show how geometric phases may be used to fully describe quantum systems, with or without gravity, by providing knowledge about the geometry and topology of its Hilbert space. We…
Geometric Quantum Discord Signals Non-Factorization
Souvik Banerjee, Pablo Basteiro, Rathindra Nath Das +1
We propose the information-theoretic quantity of geometric quantum discord (GQD) as an indicator of the factorization properties of a given quantum system. In particular, we show h…
Disorder in AdS/CFT
Moritz Dorband, Daniel Grumiller, René Meyer +1
We perturbatively study marginally relevant quenched disorder in AdS/CFT to second order in the disorder strength. Using the Chern-Simons formulation of AdS gravity for…
Berry phases, wormholes and factorization in AdS/CFT
Souvik Banerjee, Moritz Dorband, Johanna Erdmenger +2
For two-dimensional holographic CFTs, we demonstrate the role of Berry phases for relating the non-factorization of the Hilbert space to the presence of wormholes. The wormholes ar…
Geometric phases distinguish entangled states in wormhole quantum mechanics
Flavio S. Nogueira, Souvik Banerjee, Moritz Dorband +3
We establish a relation between entanglement in simple quantum mechanical qubit systems and in wormhole physics as considered in the context of the AdS/CFT correspondence. We show…
