Spread complexity for measurement-induced non-unitary dynamics and Zeno effect
Aranya Bhattacharya, Rathindra Nath Das, Bidyut Dey +1
Using spread complexity and spread entropy, we study non-unitary quantum dynamics. For non-hermitian Hamiltonians, we extend the bi-Lanczos construction for the Krylov basis to the…
Parity anomaly with impurities and the Pauli--Villars subtraction
Ozório Holanda, René Meyer, Dmitri Vassilevich
We calculate the anomalous part of the polarization tensor of Dirac fermions in dimensions in the presence of impurities described by the scattering rate for arbitrary ex…
Symmetry-resolved modular correlation functions in free fermionic theories
Giuseppe Di Giulio, Johanna Erdmenger
As a new ingredient for analyzing the fine structure of entanglement, we study the symmetry resolution of the modular flow of -invariant operators in theories endowed with a…
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…
Fracton-elasticity duality on curved manifolds
Lazaros Tsaloukidis, José J. Fernández-Melgarejo, Javier Molina-Vilaplana +1
The mechanical properties of crystals on curved substrates mix elastic, geometric and topological degrees of freedom. In order to elucidate the properties of such crystals we formu…
Electric conductivity in non-Hermitian holography
Zhuo-Yu Xian, David Rodríguez Fernández, Zhaohui Chen +2
We study the phase structure and charge transport at finite temperature and chemical potential in the non-Hermitian PT-symmetric holographic model of arXiv:1912.06647. The non-Herm…
