Chirped Pulses Meet Quantum Dots: Innovations, Challenges, and Future Perspectives
Advanced Quantum Technologies, Volume 8, Issue 2, February 2025.Chirped laser pulse excitation is the most robust method to generate high‐quality photon states from quantum dots. Here, a comprehensive overview of methods is presented to produce and characterize chirped pulses, by providing numerical design examples with experimental advantages and challenges in each.

Int.J.Mod.Phys.D11:1585-1590,2002, 2002 Spacetime is composed of a fluctuating arrangement of bubbles or loops called spacetime foam, or quantum foam. We use the holographic principle to deduce its structure, and show that the result is consistent with gedanken experiments involving spacetime measurements.

Quantification of Interfacial Charges in Multilayered Nanocapacitors by Operando Electron Holography
Advanced Materials, Volume 37, Issue 4, January 29, 2025.Operando off‐axis electron holography is used to quantify the charges trapped at the dielectric/dielectric interfaces and metal/dielectric interfaces in HfO2‐ and Al2O3‐based nanocapacitors. The electrostatic potential maps, recorded with a sub‐nanometer spatial resolution while applying a bias, demonstrate that these interfaces present a high density ...

Plasma diagnostics using digital holographic interferometry [PDF]
arXiv, 2008 The advances in Charge Coupled Devices in one hand and the high resolution measurements of holographic technique on the other hand, we have adopted the method of digital real-time holographic interferometry for the diagnostics of high density plasma. The measured values of plasma electron density agree with the measurements from other techniques.
