Comparison of Two Optimization Methods for a Rydberg Quantum Gate
Luis S. Yagüe Bosch, Sandro Wimberger
A shortcut-to-adiabaticity is compared with a numerically optimized protocol for implementing a high-fidelity quantum gate on Rydberg atoms. The counterdiabatic method offers an an…
Excitation of narrow x-ray transitions in thin-film cavities by focused pulses
Dominik Lentrodt, Christoph H. Keitel, Jörg Evers
A method to compute the excitation of narrow transitions at hard x-ray energies by short focused x-ray pulses is developed. In particular, the effect of thin-film cavities on the p…
Towards nonlinear optics with Mössbauer nuclei using x-ray cavities
Dominik Lentrodt, Christoph H. Keitel, Jörg Evers
Strong excitation of nuclear resonances, particularly of Mössbauer nuclei, has been a longstanding goal and the advance of novel x-ray sources is promising new options in this rega…
Production of entangled x rays through nonlinear double Compton scattering
T. D. C. de Vos, J. J. Postema, B. H. Schaap +2
An accessible tabletop source for the production of entangled x rays is crucial for the field of high-energy quantum optics. Here, we present a detailed analysis of the entanglemen…
Decoherence-Free Entropic Gravity for Dirac Fermion
Eric J. Sung, Andre G. Campos, Hartmut Abele +1
The theory of entropic gravity conjectures that gravity emerges thermodynamically rather than being a fundamental force. One of the main criticisms of entropic gravity is that it w…
Observing dynamical phases of BCS superconductors in a cavity QED simulator
Dylan J. Young, Anjun Chu, Eric Yilun Song +7
In conventional Bardeen-Cooper-Schrieffer (BCS) superconductors, electrons with opposite momenta bind into Cooper pairs due to an attractive interaction mediated by phonons in the…
Hadronic vacuum polarization correction to atomic energy levels
Sören Breidenbach, Eugen Dizer, Halil Cakir +1
The shift of atomic energy levels due to hadronic vacuum polarization is evaluated in a semiempirical way for hydrogenlike ions and for muonic hydrogen. A parametric hadronic polar…
Relativistic dynamical inversion in manifestly covariant form
A. G. Campos, Luca Fabbri
The Relativistic Dynamical Inversion technique, a novel tool for finding analytical solutions to the Dirac equation, is written in explicitly covariant form. It is then shown how t…
Inverse design in nuclear quantum optics: From artificial x-ray multi-level schemes to spectral observables
Oliver Diekmann, Dominik Lentrodt, Jörg Evers
Ensembles of Mössbauer nuclei embedded in thin-film cavities form a promising platform for x-ray quantum optics. A key feature is that the joint nuclei-cavity system can be conside…
Angular-Radial Integrability of Coulomb-like Potentials in Dirac Equations
Luca Fabbri, Andre G. Campos
We consider the Dirac equation, written in polar formalism, in presence of general Coulomb-like potentials, that is potentials arising from the time component of the vector potenti…
Sub-femtosecond optical control of entangled states
Farshad Shobeiry, Patrick Fross, Hemkumar Srinivas +3
For photo-dissociation of a single hydrogen molecule (H2) with combined XUV and IR laser pulses, we demonstrate optical control of the emission direction of the photoelectron with…
Inverse design of artificial two-level systems with Mössbauer nuclei in thin-film cavities
Oliver Diekmann, Dominik Lentrodt, Jörg Evers
Thin-film cavities containing layers of Mössbauer nuclei have been demonstrated to be a rich platform for x-ray quantum optics. At low excitation, these systems can be described by…
Certifying multi-mode light-matter interaction in lossy resonators
Dominik Lentrodt, Oliver Diekmann, Christoph H. Keitel +2
Quantum models based on few-mode Master equations have been a central tool in the study of resonator quantum electrodynamics, extending the seminal single-mode Jaynes-Cummings mode…
Tank-Circuit Assisted Coupling Method for Sympathetic Laser Cooling
Bingsheng Tu, Felix Hahne, Ioanna Arapoglou +9
We discuss the coupling of the motion of two ion species in separate Penning traps via a common tank circuit. The enhancement of the coupling assisted by the tank circuit is demons…
Superradiance and anomalous hyperfine splitting in inhomogeneous ensembles
Petar Andrejić, Adriana Pálffy
Collective effects in the interaction of light with ensembles of identical scatterers play an important role in many fields of physics. However, often the term ``identical'' is not…
Decomposition of the transition phase in multi-sideband RABBITT schemes
Divya Bharti, David Atri-Schuller, Gavin Menning +6
Reconstruction of Attosecond Beating By Interference of Two-photon Transitions (RABBITT) is a technique that can be used to determine the phases of atomic transition elements in ph…
Construction of Dirac spinors for electron vortex beams in background electromagnetic fields
Andre G. Campos, Karen Z. Hatsagortsyan, Christoph H. Keitel
Exact solutions of the Dirac equation, a system of four partial differential equations, are rare. The vast majority of them are for highly symmetric stationary systems. Moreover, o…

Xiangjin Kong, Darrick E. Chang, Adriana Pálffy
The resonant interaction between x-ray photons and nuclei is one of the most exciting subjects of the burgeoning field of x-ray quantum optics. A resourceful platform used so far a…
The onset time of Fermi's golden rule
V. Debierre, E. Lassalle
Fermi's golden rule describes the decay dynamics of unstable quantum systems coupled to a reservoir, and predicts a linear decay in time. Although it arises at relatively short tim…
