摘要: We consider the interaction between two identical two-level atoms prepared in superposition states and an SU(1 and the Perelomov coherent parameter , as well as the atomic phase parameters.关键词: two two-level atoms entanglement quantum correlations ...
A free-standing two-dimensional sheet composed solely of Mo atoms shows metallic character, with an electrical conductivity of ~940 S m−1. Tumesh Kumar Sahu ,Nishant Kumar &Prashant Kumar Article|31 August 2023 Atomically precise vacancy-assembled quantum antidots ...
In this scenario, the interaction strength—either the dipole–dipole coupling, J, or more often the weaker second-order van der Waals shift, V—is larger than the coupling ΩCW from ground to Rydberg states with continuous-wave (CW) lasers, such that excitation of two atoms is prohibited....

This also demonstrated photocatalytic overall water splitting ability in the absence of a sacrificial agent or precious metal. More significantly, the proposed photocatalyst effectively absorbed water and performed water splitting under simulated Mars conditions; the 70 h averaged hydrogen and oxygen ...

In a recent work [56], we studied a system of two coupled atoms (qubits) with dipole–dipole interaction in the presence of an off-resonance radiation field. We presented an analytic solution for the time evolution of the system and showed how the combined effect of the dipole coupling and...
The purpose of invoking structuralism is to demonstrate the feasibility of a transdisciplinary methodology bridging the Two (or more than Two) Cultures. 2. The Two Cultures or Many More? 2.1. The Two Cultures and Other Divisions The story of the Tower of Babel, explaining the diversity of ...
What is formed when elements of matter are chemically combined? What is formed when particles of two or more substances are distributed evenly among each other? What bond is formed when electrons are shared between atoms? When two hydrogen atoms chemically bond to one oxygen atom, what do they...
