The ALICE collaboration is a large group of researchers from over 100 physics institutes worldwide that focuses on the study of quark-gluon plasma using data collected by the ALICE (A Large Ion Collider Experiment) detector. ALICE is a heavy-ion detector designed to...

A new test to investigate the origin of cosmic structure
Many cosmologists believe that the universe's structure is a result of quantum fluctuations that occurred during early expansion. Confirming this hypothesis, however, has proven highly challenging so far, as it is hard to discern between quantum and classical...
A method to predict the properties of complex quantum systems
Predicting the properties of complex quantum systems is a crucial step in the development of advanced quantum technologies. While research teams worldwide have already devised a number of techniques to study the characteristics of quantum systems, most of these have...
Probing the properties of a 2-D fermi gas
When a new physical system is created or uncovered, researchers generally study it in depth to unveil its distinctive properties and characteristics. For example, they might try to determine how the system reacts when it is disturbed, and in what ways this disturbance...
Researchers apply the anti-de Sitter/conformal field theory to cosmology
The anti-de Sitter/conformal field theory (AdS/CFT) correspondence, also referred to as gauge/gravity duality, hypothesizes the existence of a relationship between two types of physics theories, namely gravity theories in AdS spacetimes and CFTs. Over the past few...
Investigating the interplay between axions and dark photons in the early universe
Axions and dark photons are two of the most promising types of particles for unveiling new physics. The axion scalar field explains the absence of an electric dipole moment for the neutron, while the dark photon resembles regular photons responsible for...
Simultaneous nodal superconductivity and broken time-reversal symmetry in CaPtAs
In the vast majority of superconducting materials, Cooper pairs have what is known as even parity, which essentially means that their wave function does not change when electrons swap spatial coordinates. Conversely, some unconventional superconductors have been found...
A quantum metrology protocol for locating noncooperative targets in 3-D space
Radar technology, which stands for radio detection and ranging, has been around for several decades and has a wide range of real-world applications. Radar is currently used to detect targets or other objects in many settings. For instance, it is employed during...
A quantum memory that operates at telecom wavelengths
To create large quantum networks, researchers will first need to develop efficient quantum repeaters. A key component of these repeaters are quantum memories, which are the quantum-mechanical equivalents of more conventional computer memories, such as random-access...
A new theorem predicts that stationary black holes must have at least one light ring
Black holes, regions in space with such an intense gravitational field that no matter or radiation can escape from them, are among the most mysterious and fascinating cosmological phenomena. Over the past five years or so, astrophysicists collected the first...
