Nonlinear Dynamics of a Cavity Containing a Two-Mode Coherent Field Interacting with Two-Level Atomic Systems

Applied Sciences, 2020
This study analytically explored two coupled two-level atomic systems (TLAS) as two qubits interacting with two modes of an electromagnetic field (EMF) cavity via two-photon transitions in the presence of dipole–dipole interactions between the atoms and ...

Breaking the limits of purification: postselection enhances heat-bath algorithmic cooling

Journal of Physics Communications, 2023
Quantum technologies require pure states, which are often generated by extreme refrigeration. Heat-bath algorithmic cooling is the theoretically optimal refrigeration technique: it shuttles entropy from a multiparticle system to a thermal bath, thereby ...

Cybersecurity Driven Quantum Digital Twin for Proactive Threat Reversal in Open RAN

IET Quantum Communication, Volume 7, Issue 1, January/December 2026.
This paper presents a novel cybersecurity‐driven quantum digital twin (CQDT) architecture for proactive defence in 6G Open RAN. By integrating quantum observables and reinforcement learning, the framework maintains high fidelity and suppresses entropy under adversarial CPTP noise. CQDT achieves real‐time adaptation with sub‐20 ms latency, meeting URLLC

Honorary Whites and Overlooked People of Color: The Racial Conundrum of Multiracial Americans and Asian Americans

Sociology Compass, Volume 20, Issue 1, January 2026.
ABSTRACT Multiracial Americans and Asian American populations are two of the fastest growing racial groups in the United States. Our article is the first to highlight three similarities that show how these groups are uniquely racially misunderstood: (a) both are subsumed under racial umbrella terms that obscure tremendous diversity, (b) both have been ...

From bound states to quantum spin models: chiral coherent dynamics in topological photonic rings

Nanophotonics, Volume 14, Issue 24, Page 4397-4409, December 2025.
Abstract Topological photonic systems offer a robust platform for guiding light in the presence of disorder, but their interplay with quantum emitters remains a frontier for realizing strongly correlated quantum states. Here, we explore a ring‐shaped Su‐Schrieffer‐Heeger (SSH) photonic lattice interfaced with multiple quantum emitters to control ...

Turbulent Exchange of CO2 ${\text{CO}}_{2}$ in the Lower Tropical Troposphere Across Clear‐to‐Cloudy Conditions

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 19, 16 October 2025.
Abstract This study investigates the roles of clear air entrainment and shallow cloud ventilation, alongside rainforest CO2 ${\text{CO}}_{2}$‐assimilation, in the turbulent exchange of CO2 ${\text{CO}}_{2}$ within the lower tropical troposphere under clear‐to‐cloudy conditions.

Quasi-Probability Husimi-Distribution Information and Squeezing in a Qubit System Interacting with a Two-Mode Parametric Amplifier Cavity

Mathematics, 2020
Squeezing and phase space coherence are investigated for a bimodal cavity accommodating a two-level atom. The two modes of the cavity are initially in the Barut–Girardello coherent states. This system is studied with the SU(1,1)-algebraic model.

Studying mixing in Non-Newtonian blue maize flour suspensions using color analysis. [PDF]

PLoS ONE, 2014
BACKGROUND: Non-Newtonian fluids occur in many relevant flow and mixing scenarios at the lab and industrial scale. The addition of acid or basic solutions to a non-Newtonian fluid is not an infrequent operation, particularly in Biotechnology applications

Elastic Properties of Returned Samples From Asteroid (162173) Ryugu

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The successful sample return from asteroid (162173) Ryugu by Hayabusa2 has contributed to our understanding of the solar system evolution. Over the course of the initial sample analysis, various measurements were conducted, such as mineralogical observation, chemical analysis, and mechanical property measurement.
