Negative Stiffness Induced and Controlled by Constriction

open access: yesphysica status solidi (b), EarlyView.
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).

Ambient Condition Superconductivity via Engineered Polaronic Environment

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
A novel strategy for increasing the critical temperature Tc of superconductors is proposed. It involves mating ultrathin layers of superconductors (e.g. MgB2) and metal‐organic framework materials, with a renormalized dielectric response yielding a new system with strengthened Cooper pairing via resonant antishielding. This study's estimates of Tc show

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

High‐Purity Single‐Photon Emission in the Telecom O‐Band from Droplet‐Epitaxy InAs Quantum Dots Integrated into a GaAs/AlGaAs Planar Microcavity on Vicinal GaAs(111)A Platform

open access: yesAdvanced Quantum Technologies, EarlyView.
High‐purity single‐photon emission at telecom O‐band is demonstrated from droplet‐epitaxy InAs quantum dots embedded in a GaAs/AlGaAs microcavity. Strain engineering via an InAlAs buffer enables broadband telecom emission with high purity, short lifetimes, and enhanced extraction.

Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...
