Duality between string and computational order in symmetry-enriched topological phases
Paul Herringer, Vir B. Bulchandani, Younes Javanmard +2
We present the first examples of topological phases of matter with uniform power for measurement-based quantum computation. This is possible thanks to a new framework for analyzing…

Accessing eigenstate spin-glass order from reduced density matrices
Younes Javanmard, Soumya Bera, Markus Heyl
Many-body localized phases may not only be characterized by their ergodicity breaking, but can also host ordered phases such as the many-body localized spin-glass (MBL-SG). The MBL…

Sharp entanglement thresholds in the logarithmic negativity of disjoint blocks in the transverse-field Ising chain
Younes Javanmard, Daniele Trapin, Soumya Bera +2
Entanglement has developed into an essential concept for the characterization of phases and phase transitions in ground states of quantum many-body systems. In this work, we use th…
