Atomic‐Scale Epitaxy for Tailoring Crystalline GeSbTe Alloys Into Bidimensional Phases

Advanced Materials Interfaces, EarlyView.
This Study Shows How Molecular Beam Epitaxy Can Precisely Control the Growth of Ge–Sb–Te Alloys By Tuning Temperature and Elemental Flux Ratio. A Predictive Growth Diagram is established, Linking Structural Ordering to Electrical Transport, and Enabling Efficient, low‐power Switching in Memory Devices.

Investigating and controlling the quantum resources of bipartite-qubit detectors of scalar fields in the process of spacetime expansion

European Physical Journal C: Particles and Fields, 2023
Quantum resources construct new avenues to explore the cosmos. Considering bipartite-qubit detectors subjected to scalar fields in an expanding spacetime, quantum resources (including quantum coherence, quantum discord, Bell-nonlocality, and nonlocal ...

Creation of quantum correlations between two atoms in a dissipative environment from an initial vacuum state

, 2012
We have investigated the effect of counter-rotating terms on the dynamics of entanglement and quantum discord between two identical atoms interacting with a lossy single mode cavity field for a system initially in a vacuum state.

Self‐Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Axial Heterostructures Grown by Molecular Beam Epitaxy

Advanced Materials Interfaces, EarlyView.
Following the parameter modulation described in the manuscript, a high yield of branch‐free self‐catalyzed AlGaAs nanowires at various nominal Al contents with high material quality has been acquired. These branchless structures are ideal hosts for narrower bandgap GaAs quantum dots, promising for non‐classical light‐emitting applications.

Correlations in Two-Qubit Systems under Non-Dissipative Decoherence

Axioms, 2020
We built a new set of suitable measures of correlations for bipartite quantum states based upon a recently introduced theoretical framework [Bussandri et al. in Quantum Inf. Proc. 18:57, 2019].

Quantum correlations in the collective spin systems

, 2012
Quantum and classical pairwise correlations in two typical collective spin systems (i.e., the Dicke model and the Lipkin-Meshkov-Glick model) are discussed.

Nanophotonic Strategies for Chiral Biosensing: Nanoparticles, Metasurfaces, Magneto‐Optical, and Quantum Approaches

Advanced Photonics Research, EarlyView.
Recent advances in nanophotonics‐based chiral biosensing approaches are comprehensively reviewed, highlighting key trends, advantages, and limitations of each technology. Special attention is given to emerging strategies that exploit magneto‐optical and quantum plasmonic phenomena to enhance sensitivity down to the level of a few molecules, or even a ...

Impact of Intended Isocaloric Early versus Late Time‐Restricted Eating on Plasma Lipidome in Women with Overweight or Obesity: Secondary Analysis of the ChronoFast Trial

Advanced Science, EarlyView.
Women with overweight or obesity follow intended isocaloric early and late time‐restricted eating (TRE) in a crossover trial. Shotgun plasma lipidomics reveals no significant differences between interventions, but identify pronounced lipid changes—including reductions in ceramides and phosphatidylcholines—within the early TRE.

Quantum discord evolution of three-qubit states under noisy channels

, 2012
We investigated the dissipative dynamics of quantum discord for correlated qubits under Markovian environments. The basic idea in the present scheme is that quantum discord is more general, and possibly more robust and fundamental, than entanglement ...
