In spaces smaller than a wavelength of light, electric currents jump from point to point and magnetic fields corkscrew through atomic lattices in ways that defy intuition. Scientists have only ever dreamed of observing these ...
Phonons are sound particles or quantized vibrations of atoms in solid materials. The Debye model, a theory introduced by physicist Peter Debye in 1912, describes the contribution of phonons to the specific heat of materials ...
Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla (T), spins (i.e., intrinsic ...
Electricity powers our lives, including our cars, phones, computers, and more, through the movement of electrons within a circuit. While we can't see these electrons, electric currents moving through a conductor flow like ...
A theoretical framework predicts the emergence of non-reciprocal interactions that effectively violate Newton's third law in solids using light, report researchers from Japan. They demonstrate that by irradiating light of ...
Bose-Einstein condensates (BECs) are fascinating states of matter that emerge when atoms or molecules are cooled to extremely low temperatures just slightly above absolute zero (0 K). In 2023, physicists at Columbia University ...
The simulation of strongly interacting many-body systems is a key objective of quantum physics research, as it can help to test the predictions of physics theories and yield new valuable insight. Researchers at Quantinuum, ...
The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly Interacting Massive Particles, ...
Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century. While conventional superconductors are well understood, a new class of materials known as topological ...
Ferrimagnets are a special type of magnet where different atoms' magnetic moments partially cancel each other out, creating a rich internal structure. They are widely used in technologies from magneto-optical devices to spin-based ...
