Holographic interference in atomic photoionization from a semiclassical standpoint [PDF]
, 2019 A theoretical study of the interference pattern imprinted on the doubly differential momentum distribution of the photoelectron due to atomic ionization induced by a short laser pulse is developed from a semiclassical standpoint. We use the semiclassical

Localizing Gravitational Wave Sources with Single-Baseline Atom Interferometers [PDF]
, 2017 Localizing sources on the sky is crucial for realizing the full potential of gravitational waves for astronomy, astrophysics, and cosmology. We show that the mid-frequency band, roughly 0.03 to 10 Hz, has significant potential for angular localization ...

Current and future perspectives of positronium and muonium spectroscopy as dark sectors probe [PDF]
, 2019 Positronium and Muonium are purely leptonic atoms and hence free of an internal sub-structure. This qualifies them as potentially well suited systems to probe the existence of physics beyond the Standard Model. We hence carry out a comprehensive study of

Dynamics of a single ion spin impurity in a spin-polarized atomic bath [PDF]
, 2018 We report on observations of spin dynamics in single Yb$^+$ ions immersed in a cold cloud of spin-polarized $^6$Li atoms. This species combination has been proposed to be the most suitable system to reach the quantum regime in atom-ion experiments. For $^

Momentum transfers in correlation-assisted tunnelling [PDF]
, 2013 We consider correlation-assisted tunnel ionization of a small molecule by an intense low-frequency laser pulse. In this mechanism, the departing electron excites the state of the ion via a Coulomb interaction.

Frequency shifts in noble-gas magnetometers
, 2019 Polarized nuclei are a powerful tool in nuclear spin studies and in searches for beyond-the-standard model physics. Noble-gas comagnetometer systems, which compare two nuclear species, have thus far been limited by anomalous frequency variations of ...

Review of experimental and theoretical status of the proton radius puzzle [PDF]
, 2017 The discrepancy between the measured Lamb shift in muonic hydrogen and expectations from electron-proton scattering and regular hydrogen spectroscopy has become known as the proton radius puzzle, whose most "mundane" resolution requires a $> 5 \sigma ...
