Quantum and classical entropic complexity of the thermal state: coherence, decoherence, and the ergodic-to-localized crossover in random-matrix and many-body models
Imre Varga, Onur Aktan
Does thermal averaging preserve signatures of eigenstate complexity? We study the entropic complexity C = S_1 - S_2 (Shannon minus second-order Renyi entropy) across the ergodic-to…
Complexity in multi-qubit and many-body systems
Imre Varga
Characterizing complexity and criticality in quantum systems requires diagnostics that are both computationally tractable and physically insightful. We apply a measure of quantum s…
Complexity of two-level systems
Imre Varga
Complexity of two-level systems, e.g. spins, qubits, magnetic moments etc, are analysed based on the so-called correlational entropy in the case of pure quantum systems and the the…
A Lloyd-model generalization: Conductance fluctuations in one-dimensional disordered systems
J. A. Mendez-Bermudez, A. J. Martinez-Mendoza, V. A. Gopar +1
We perform a detailed numerical study of the conductance through one-dimensional (1D) tight-binding wires with on-site disorder. The random configurations of the on-site energi…
