Information Scrambling and the Correspondence of Entanglement- and Operator Dynamics in Systems with Nonlocal Interactions
Darvin Wanisch, Juan Diego Arias Espinoza, Stephan Fritzsche
How fast quantum information scrambles such that it becomes inaccessible by local probes turns out to be central to various fields. Motivated by recent works on spin systems with n…
Redefined vacuum approach and gauge-invariant subsets in two-photon-exchange diagrams for a closed-shell system with a valence electron
R. N. Soguel, A. V. Volotka, E. V. Tryapitsyna +3
The two-photon-exchange diagrams for atoms with single valence electrons are investigated. Calculation formulas are derived for an arbitrary state within the rigorous bound-state Q…
Near K-Edge Photoionization and Photoabsorption of Singly, Doubly, and Triply Charged Silicon Ions
S. Schippers, S. Stock, T. Buhr +5
Experimental and theoretical results are presented for double, triple, and quadruple photoionization of Si and Si ions and for double photoionization of Si ions b…
Multiple photodetachment of silicon anions via K-shell excitation and ionization
A. Perry-Sassmannshausen, T. Buhr, M. Martins +5
Experimental cross sections for -fold photodetachment () of silicon anions via -shell excitation and ionization were measured in the photon-energy range of 1830-1900 e…
Torus Knot Angular Momentum in Twisted Attosecond Pulses from High Harmonic Generation
Björn Minneker, Birger Böning, Anne Weber +1
Bicircular twisted Laguerre-Gaussian beams possess a definite torus knot angular momentum (TKAM) as a new form of angular momentum. TKAM is conserved in nonlinear atomic processes…
Delocalization of quantum information in long-range interacting systems
Darvin Wanisch, Stephan Fritzsche
We investigate the delocalization of quantum information in the nonequilibrium dynamics of the spin chain with asymptotically decaying interactions . As a figure o…
