Understanding Quantum Materials
The staple of material science, particularly in the quantum realm, has been the pursuit of understanding how materials function on atomic and subatomic levels. Quantum materials hold immense significance due to their unique properties and behaviors as governed by quantum mechanics. Unlike classical materials, whose properties are straightforwardly described by Newtonian physics, quantum materials exhibit complex interactions that defy classical logic. These interactions arise from the principles of quantum mechanics, such as superposition, entanglement, and the quantization of energy levels. Delving into these underlying principles reveals why quantum materials are at the forefront of transformative technological advancements.
The allure of quantum materials is primarily rooted in their atomic and subatomic intricacies. At these scales, electrons do not follow deterministic paths as classical particles would.
