Complexity from the Reduced Density Matrix: a new Diagnostic for Chaos
Arpan Bhattacharyya, S. Shajidul Haque, Eugene H. Kim
We investigate circuit complexity to characterize chaos in multiparticle quantum systems. In the process, we take a stride to analyze open quantum systems by using complexity. We p…
Chaos and Complexity in Quantum Mechanics
Tibra Ali, Arpan Bhattacharyya, S. Shajidul Haque +3
We propose a new diagnostic for quantum chaos. We show that time evolution of complexity for a particular type of target state can provide equivalent information about the classica…
Post-Quench Evolution of Complexity and Entanglement in a Topological System
Tibra Ali, Arpan Bhattacharyya, S. Shajidul Haque +2
We investigate the evolution of complexity and entanglement following a quench in a one-dimensional topological system, namely the Su-Schrieffer-Heeger model. We demonstrate that c…
Time Evolution of Complexity: A Critique of Three Methods
Tibra Ali, Arpan Bhattacharyya, S. Shajidul Haque +2
In this work, we propose a testing procedure to distinguish between the different approaches for computing complexity. Our test does not require a direct comparison between the app…
Quantum manipulation via atomic-scale magnetoelectric effects
Anh. T. Ngo, J. Rodriguez-Laguna, S. E. Ulloa +1
Magnetoelectric effects at the atomic scale are demonstrated to afford unique functionality. This is shown explicitly for a quantum corral defined by a wall of magnetic atoms depos…
Spatial correlations in chaotic nanoscale systems with spin-orbit coupling
Anh T. Ngo, Eugene H. Kim, Sergio E. Ulloa
We investigate the statistical properties of wave functions in chaotic nanostructures with spin-orbit coupling (SOC), focussing in particular on spatial correlations of eigenfuncti…
