Quantum superchemistry: What is it? Know about the phenomenon observed for the first time by scientists

economictimes.indiatimes.com:

quantum superchemistry manifests when atoms or molecules sharing the same quantum state engage in chemical reactions at a heightened pace compared to those in differing quantum states. A quantum state encompasses specific characteristics of a quantum particle, such as its energy level or angular momentum.

In their pursuit of unveiling this novel phenomenon, scientists undertook the challenge of aligning entire molecules within the same quantum state. The outcomes of their efforts revealed that chemical reactions ensued collectively rather than individually when atoms or molecules partook in the same quantum state. Additionally, the researchers observed that denser collections of atoms led to accelerated chemical reactions, reinforcing the phenomenon's occurrence.

Cheng Chin, a physics professor at the University of Chicago who spearheaded the research, emphasized the alignment of their findings with theoretical predictions. He expressed the significance of this accomplishment, remarking, «This has been a scientific goal for 20 years, so it's a very exciting era.»

The team's study, published in Nature Physics on July 24, centered on cesium atoms forming molecules. To create the conditions for observation, the researchers cooled cesium gas nearly to absolute zero, arresting all motion. In this cooled environment, they skillfully orchestrated each cesium atom to assume the same quantum state. By manipulating the surrounding magnetic field, they initiated the chemical bonding of these atoms.

The outcome was revelatory: cesium
