Quantum storage with flat bands
Carlo Danieli, Jie Liu, Rudolf A. Römer +1
The realization of robust quantum storage devices relies on the ability to generate long-lived, spatially localized quantum states. In this work, we introduce a method for the targ…

Spectral and Entanglement Properties of the Random Exchange Heisenberg Chain
Yilun Gao, Rudolf A. Römer
We study the many-body localization problem in the non-abelian SU(2)-invariant random antiferromagnetic exchange model in 1D. Exact and sparse matrix diagonalization methods are us…

Machine learning of phases and structures for model systems in physics
Djenabou Bayo, Burak ÃivitcioÄlu, Joseph J Webb +2
The detection of phase transitions is a fundamental challenge in condensed matter physics, traditionally addressed through analytical methods and direct numerical simulations. In r…
