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…

Real-space renormalisation approach to the Chalker-Coddington model revisited: improved statistics
Syl Shaw, Rudolf A. Römer
The real-space renormalisation group method can be applied to the Chalker-Coddington model of the quantum Hall transition to provide a convenient numerical estimation of the locali…

Phase determination with and without deep learning
Burak Çivitcioğlu, Rudolf A. Römer, Andreas Honecker
Detection of phase transitions is a critical task in statistical physics, traditionally pursued through analytic methods and direct numerical simulations. Recently, machine-learnin…
