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 ...

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

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 $^

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

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.

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 ...

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 ...

Recollision scenario without tunneling : Role of the ionic core potential [PDF]
, 2013 The standard model of strong laser physics, the recollision scenario, omits the ionic core potential after tunneling. Strikingly, although the Coulomb interaction drives all stages of recollision, the maximum energy the electrons bring back to the core ...

Variation of fundamental constants in space and time: theory and observations
, 2008 Review of recent works devoted to the temporal and spatial variation of the fundamental constants and dependence of the fundamental constants on the gravitational potential (violation of local position invariance) is presented. We discuss the variation

Constraints on muon-specific dark forces
, 2014 The recent measurement of the Lamb shift in muonic hydrogen allows for the most precise extraction of the charge radius of the proton which is currently in conflict with other determinations based on $e-p$ scattering and hydrogen spectroscopy.
