The Alpha Magnetic Spectrometer (AMS) collaboration, a large group of researchers from CERN and other institutes worldwide, has recently presented a series of precision measurements of the properties of cosmic Helium isotopes 3He and 4He. These measurements were...
Researchers at the MIT-Harvard Center for ultracold atoms and research laboratory of electronics have proposed a new method for producing 3-D Bose-Einstein condensates using laser cooling only. In their study, featured in Physical Review Letters, they demonstrated the...
In quantum physics, scrambling is the dispersal of quantum information across a complex quantum system, such as chaotic quantum many-body systems. This process can make quantum information difficult or impossible to access, particularly when using simple and...
A team of researchers at Utrecht University, the Norwegian University of Science and Technology and the University of Konstanz has recently proposed a new method to determine magnon coherence in solid-state devices. Their study, outlined in a paper published in...
Quantum gauge theories are mathematical constructs that are typically used by physicists to describe subatomic particles, their associated wave fields and the interactions between them. The dynamics outlined by these theories are difficult to compute, yet effectively...
To date, research in quantum optics has primarily investigated the relation between light and matter using small atoms interacting with electromagnetic fields that have substantially larger wavelengths. In an unconventional new study, a team at Chalmers University of...
In physics, non-Hermitian systems are systems that cannot be described by standard (i.e., Hermitian) laws of quantum mechanics, or more precisely, that can only be described by non-Hermitian Hamiltonians. Non-Hermitian systems are ubiquitous in nature. Many open...
Although researchers have been studying dark matter and trying to observe it, its nature is a longstanding scientific mystery. The standard cosmological model suggests that approximately one-quarter of cosmological energy and matter is almost immune to electromagnetic...
A team of researchers at the University of Oxford have recently introduced a new way to model polarons, a quasiparticle typically used by physicists to understand interactions between electrons and atoms in solid materials. Their method, presented in a paper published...
Superconducting circuits, which have zero electrical resistance, could enable the development of electronic components that are significantly more energy-efficient than most chips used today. Importantly, superconducting circuits rely on an electronic element known as...
