Time-evolution of tripartite quantum discord and entanglement under local and non-local random telegraph noise

open access: yes, 2013
Few studies explored the dynamics of non-classical correlations besides entanglement in open multipartite quantum systems. Here, we address the time-evolution of quantum discord and entanglement in a model of three non-interacting qubits subject to a ...

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes

open access: yesAdvanced Materials, EarlyView.
A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.

On the Effect of Random Alternating Perturbations on Hazard Rates

open access: yes, 2006
We consider a model for systems perturbed by dichotomous noise, in which the hazard rate function of a random lifetime is subject to additive time-alternating perturbations described by the telegraph process.

Non linear transport properties of an insulating YBCO nano-bridge

open access: yes, 2009
We have investigated the transport properties of an insulating sub-micrometric YBa2Cu3O7-d bridge, patterned on a thin film. As expected for a variable-range-hopping insulator, transport is found non linear.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Super-reflection of light from a random amplifying medium with disorder in the complex refractive index : Statistics of fluctuations

open access: yes, 1999
The probability distribution of the reflection coefficient for light reflected from a one-dimensional random amplifying medium with {\it cross-correlated} spatial disorder in the real and the imaginary parts of the refractive index is derived using the ...

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

open access: yesAdvanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

From Random Telegraph to Gaussian Stochastic Noises: Decoherence and Spectral Diffusion in a Semiconductor Quantum Dot

open access: yesAdvances in Mathematical Physics, 2010
We present a general theoretical description of the extrinsic dephasing mechanism of spectral diffusion that dominates the decoherence dynamics in semiconductor quantum dots at low temperature.

Computation using Noise-based Logic: Efficient String Verification over a Slow Communication Channel

open access: yes, 2010
Utilizing the hyperspace of noise-based logic, we show two string verification methods with low communication complexity. One of them is based on continuum noise-based logic.
