Author(s): Nahum C. Chávez, Francesco Mattiotti, J. A. Méndez-Bermúdez, Fausto Borgonovi, and G. Luca Celardo A study of long-range interactions in disordered systems yields a surprising result: Transport can increase with disorder. [Phys. Rev. Lett. 126, 153201] Published Mon Apr 12, 2021

Author(s): M. B. Christensen, T. Vibel, A. J. Hilliard, M. B. Kruk, K. Pawłowski, D. Hryniuk, K. Rzążewski, M. A. Kristensen, and J. J. Arlt Quantum systems are typically characterized by the inherent fluctuation of their physical observables. Despite this fundamental importance, the investigation of the fluctuations in interacting quantum systems at finite temperature continues to pose considerable theoretical and experimental challenge... ...

Löffler Coherent optical states consist of a quantum superposition of different photon number (Fock) states, but because they do not form an orthogonal basis, no photon number states can be obtained from it by linear optics. Here we demonstrate the reverse, by manipulating a random continuous...

Author(s): Alexey Shkarin, Dominik Rattenbacher, Jan Renger, Simon Hönl, Tobias Utikal, Paul Seidler, Stephan Götzinger, and Vahid Sandoghdar We present efficient evanescent coupling of single organic molecules to a gallium phosphide (GaP) subwavelength waveguide (nanoguide) decorated with microelectrodes. By monitoring their Stark shifts, we reveal that the coupled molecules experience fluctuating electric fields. We analyze the spectral... ...

Author(s): Shane P. Kelly, Ana Maria Rey, and Jamir Marino We study the far-from-equilibrium dynamical regimes of a many-body spin-boson model with disordered couplings relevant for cavity QED and trapped ion experiments, using the discrete truncated Wigner approximation. We focus on the dynamics of spin observables upon varying the disorder strength and th... [Phys. Rev. Lett. 126, 133603] Published Fri Apr 02, 2021

Author(s): Aderonke S. Folorunso, Adam Bruner, François Mauger, Kyle A. Hamer, Samuel Hernandez, Robert R. Jones, Louis F. DiMauro, Mette B. Gaarde, Kenneth J. Schafer, and Kenneth Lopata First-principles calculations are employed to elucidate the modes of attosecond charge migration (CM) in halogenated hydrocarbon chains. We use constrained density functional theory (DFT) to emulate the creation of a localized hole on the halogen and follow the...

Author(s): F. Martinez, N. Iwe, M. Müller, K. Raspe, L. Schweikhard, J. Tiggesbäumker, and K.-H. Meiwes-Broer Combining photoelectron spectroscopy with tunable laser pulse excitation allows us to characterize the Coulomb barrier potential of multiply negatively charged silver clusters. The spectra of mass- and charge-selected polyanionic systems, with $z=2–5$ excess electrons, show a characteristic dependen... [Phys. Rev. Lett. 126, 133001...
