Quantum state tracking and control of a single molecular ion in a thermal environment

Aug 15, 2024 | science.org | Fabian Ripka |Yu Chi Liu |Julian Schmidt |Zhimin Liu

Editor’s summaryMolecular dynamics detailing the evolution of molecular states has been an intensively studied topic in the molecular and chemical physics community. However, molecular state control is often limited by the interaction between the object (the molecule) and its environment, which can cause unwanted changes in the object’s state. Liu et al. present an approach in which the state of the molecule is preserved by actively correcting environment-induced transitions.

Hebbian instruction of axonal connectivity by endogenous correlated spontaneous activity

Aug 15, 2024 | science.org | Fabian Ripka |Naoyuki Matsumoto |Daniel Barson |Michael C. Crair

Editor’s summaryHow spontaneous activity sculpts fine-scale functional circuit connectivity before the onset of sensory experience is a fundamental question in neuroscience. Matsumoto et al. performed simultaneous imaging of retinal waves and spontaneous activity in neonatal mice while measuring morphological changes in retinal ganglion cell axons (see the Perspective by Somaiya and Feller).

Animal Behavior Faster in groupsDi JiangForaging in groups helps slower red knots speed up. PHOTO: JIM ZIPP/SCIENCE SOURCEAnimals often exhibit individual differences in behavior. In group-foraging birds, some choose to take risks and explore new territories for food alone, whereas others are more timid and scrounge on the discoveries of the bolder ones. Roncoroni et al.

Phantom energy in the nonlinear response of a quantum many-body scar state

Aug 15, 2024 | science.org | Fabian Ripka |Kangning Yang |Yicheng Zhang |Kuan-Yu Li

AbstractQuantum many-body scars are notable as nonthermal, low-entanglement states that exist at high energies. Here, we use attractively interacting dysprosium gases to create scar states that are stable enough to be driven into a strongly nonlinear regime while retaining their character. We measure how the kinetic and total energies evolve after quenching the confining potential.

PHOTO: NARAYAN MAHARJAN/NURPHOTO VIA GETTY IMAGESIn 2020, more than 2 billion people were estimated to lack access to safely managed drinking water services (1). However, the existing data on safely managed drinking water services are scarce especially in low- and middle-income countries. On page 784 of this issue, Greenwood et al.

Fabian Ripka, Harald Kübler, [...] , Robert Löw, and Tilman Pfau +1 authors fewerAuthors Info & AffiliationsOn 26 October 2018, Science published the Report “A room-temperature singlephoton source based on strongly interacting Rydberg atoms” by F. Ripka et al. (1). During a recent internal reevaluation of the data (unrelated to the Erratum posted in 2020), the authors detected mistakes in data filtering and the calculation of the size of the error bars in Fig. 3.
