Engineering thermal reservoirs for ultracold dipole–dipole-interacting Rydberg atoms

New Journal of Physics, 2018
We consider an open quantum system of ultracold Rydberg atoms. The system part consists of resonant dipole–dipole-interacting Rydberg states. The environment part is formed by ‘three-level atoms’: each atom has a ground state, a short-lived excited state,

Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function

International Statistical Review, EarlyView.
Summary Goodness‐of‐fit tests are suggested for several popular jump‐diffusion processes. The suggested test statistics utilise the marginal characteristic function of the model and its L2‐type discrepancy from an empirical counterpart. Model parameters are estimated either by minimising the aforementioned L2‐type discrepancy or by maximum likelihood ...

High-Resolution Spectroscopy of High Rydberg States: Chemical and Technological Applications

CHIMIA, 2000
High Rydberg states of atoms and molecules possess unusual properties that can be exploited in chemistry and technology. The extreme sensitivity of these states to external influences makes them ideal probes of their environment and they can be ...

Trapping potentials and quantum gates for microwave-dressed Rydberg atoms on an atom chip

Physical Review Research
Rydberg atoms in dc electric fields acquire static dipole moments. When the atoms are close to a surface producing an inhomogeneous electric field, such as by the adsorbates on an atom chip, depending on the sign of the dipole moment of the Rydberg-Stark

Quantum programming of the satisfiability problem with Rydberg atom graphs

Physical Review Research, 2023
Finding a quantum computing method to solve nondeterministic polynomial time (NP)-complete problems is currently of paramount importance in quantum information science. Here we propose and experimentally demonstrate a Rydberg atom approach to program the

Bacillus subtilis RNase HII Is Inefficient at Processing Guanosine Monophosphate and Damaged Ribonucleotides

Molecular Microbiology, EarlyView.
Bacillus subtilis RNase HII corrects ribonucleotide errors and mismatched ribonucleotides, but not damaged ribonucleotides. Mismatched ribonucleotides would also serve as substrates for mismatch repair while damaged ribonucleotides would be addressed through base excision repair.

Electrokinetic Manipulations Combined With Direct and Ambient Ionization Mass Spectrometry

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 244-259, March/April 2026.
ABSTRACT Mass spectrometry (MS) is a powerful analytical technique that typically involves sample preparation and online analytical separation before MS detection. Traditional methods often face bottlenecks in sample preparation and analytical separation, despite the rapid detection capabilities of MS.

Fast Entangling Gates for Rydberg Atoms via Resonant Dipole-Dipole Interaction

PRX Quantum
The advent of digital neutral-atom quantum computers relies on the development of fast and robust protocols for high-fidelity quantum operations. In this work, we introduce a novel scheme for entangling gates using four atomic levels per atom: a ground ...

Spin–Phonon Relaxation Dynamics from a Conical Intersection of Trapped Rydberg Ions

Photonics
Non-adiabatic processes near conical intersections are rooted in the stronger coupling between electronic and nuclear degrees of freedom. Using a system of two trapped Rydberg ions, their high polarizability and strong dipolar interactions allow to form ...

Spectroscopy of Highly Excited States of the Hydrogen Atom

CHIMIA, 2020
In this contribution, we describe the status of the development of a precision-spectroscopic experiment aimed at measuring transitions to states of high principal quantum number n of the hydrogen atom (H). These states form series (called Rydberg series)
