Entanglement Dynamics of Disordered Quantum XY Chains
Houssam Abdul-Rahman, Bruno Nachtergaele, Robert Sims +1
We consider the dynamics of the quantum XY chain with disorder under the general assumption that the expectation of the eigenfunction correlator of the associated one-particle Hami…
Fast and numerically stable circle fit
Houssam Abdul-Rahman, Nikolai Chernov
We develop a new algorithm for fitting circles that does not have drawbacks commonly found in existing circle fits. Our fit achieves ultimate accuracy (to machine precision), avoid…
A uniform area law for the entanglement of eigenstates in the disordered XY chain
Houssam Abdul-Rahman, Günter Stolz
We consider the isotropic or anisotropic XY spin chain in the presence of a transversal random magnetic field, with parameters given by random variables. It is shown that eigenfunc…
