Fast, noise-free atomic optical memory with 35-percent end-to-end efficiency

Communications Physics, 2023
Coherent optical memories will likely play an important role in future quantum communication networks. Among the different platforms, memories based on ladder-type orbital transitions in atomic gasses offer high bandwidth (>100 MHz), continuous (on ...

Quantitative measurement of orbital angular momentum in electron microscopy

, 2014
Electron vortex beams have been predicted to enable atomic scale magnetic information measurement, via transfer of orbital angular momentum. Research so far has focussed on developing production techniques and applications of these beams.

Development of dual-beamline photoelectron momentum microscopy for valence orbital analysis

Journal of Synchrotron Radiation
The soft X-ray photoelectron momentum microscopy (PMM) experimental station at the UVSOR Synchrotron Facility has been recently upgraded by additionally guiding vacuum ultraviolet (VUV) light in a normal-incidence configuration.

Shell model estimate of electric dipole moments in medium and heavy nuclei

EPJ Web of Conferences, 2015
Existence of the electric dipole moment (EDM) is deeply related with time-reversal invariance. The EDMof a diamagnetic atom is mainly induced by the nuclear Schiff moment.

Orbital coupling of hetero-diatomic nickel-iron site for bifunctional electrocatalysis of CO2 reduction and oxygen evolution

Nature Communications, 2021
Diatomic site catalysts utilize two adjacent atomic metal species for their complementary functionalities and synergistic actions. Here, the authors report the orbital coupling of hetero-diatomic nickel-iron site boosts CO2 reduction reaction and oxygen ...

On the keV sterile neutrino search in electron capture

, 2014
A joint effort of cryogenic microcalorimetry (CM) and high-precision Penning-trap mass spectrometry (PT-MS) in investigating atomic orbital electron capture (EC) can shed light on the possible existence of heavy sterile neutrinos with masses from 0.5 to ...

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Overexpression of CDT1 inhibits cell cycle progression at S phase by interacting with the mini‐chromosome maintenance complex and causes DNA damage

FEBS Open Bio, EarlyView.
CDT1 is an essential protein for DNA replication licensing that loads the MCM complex, the eukaryotic replicative DNA helicase, onto replication origins. Overexpression of CDT1 induces cell cycle arrest at the S phase. Here we showed CDT1 inhibits the progression of replication forks by interacting with the MCM complex, leading to the stalling and ...

Collective photon emission from symmetric states created with Rydberg atoms on a ring lattice

, 2010
We discuss the creation of non-classical light from collective atomic states that are prepared in a ring-shaped lattice. These states are realized by exploiting the strong interaction between atoms in high lying energy levels - so-called Rydberg states -
