Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxation processes known as conical intersections. Such dynamics, which are at the basis of many biological and chemical relevant functions, are extremely … Read more
A collaborative research team from Nanjing University of Science and Technology (NJUST) and East China Normal University (ECNU) has theoretically proposed that a pump-probe high-harmonic spectroscopy (HHS) driven by VUV-IR pulses can catch the geometric phase (GP) effect around the conical intersection (CI) and distinguish its quantitative behavior from the case of avoided crossing (AC). … Read more
The origin and evolution of the universe have fascinated humanity for millennia. Modern scientific theories, such as the Big Bang theory, provide a framework for understanding these cosmic processes. The universe began as an unimaginably dense and hot singularity around 13.8 billion years ago, expanding rapidly and cooling over time. Through cosmic inflation, galaxies, stars, … Read more
The Standard Model of Particle Physics represents one of modern physics’ crowning achievements, offering a comprehensive framework for understanding the fundamental forces and building blocks of the universe. This model has been developed through decades of experimental discoveries and theoretical advancements, culminating in a description of particles and forces that govern the behavior of matter … Read more
Chiral optical materials have garnered considerable interest across various disciplines due to their versatile applications in remote sensing, three-dimensional displays, information communication, and optical information storage. In response to the growing demand for stable and environmentally friendly materials, there is a keen anticipation surrounding two-dimensional, chiral, lead-free halide double perovskites, which are poised to exhibit … Read more
Quantum Field Theory (QFT) stands as one of the cornerstones of modern theoretical physics, providing a powerful framework for understanding the fundamental particles and forces that make up the universe. Born out of the synthesis of quantum mechanics and special relativity, quantum field theory describes particles as excitations of underlying fields permeating space and time. … Read more
