Similar to how a radio antenna plucks a broadcast from the air and concentrates the energy into a song, individual atoms can collect and concentrate the energy of light into a strong, localized signal that researchers can use to study the fundamental building blocks of matter.

Quantum field theory reveals potential flaws in models predicting numerous primordial black holes, suggesting fewer exist, which may impact theories of dark matter and the universe’s structure.

Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.

The study, which was published recently in Physical Review Letters, was conducted by researchers at the Research Center for the Early Universe (RESCEU) and Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) at the University of Tokyo.

Researchers from the Photonics Research Laboratory (PRL)-iTEAM at the Universitat Politècnica de València, in collaboration with iPRONICS, have developed a groundbreaking photonic chip. This chip is the world’s first to be universal, programmable, and multifunctional, making it a significant advancement for the telecommunications industry, data centers, and AI computing infrastructures. It is poised to enhance a variety of applications including 5G communications, quantum computing, data centers, artificial intelligence, satellites, drones, and autonomous vehicles.

The development of this revolutionary chip is the main result of the European project UMWP-Chip, led by researcher José Capmany and funded by an ERC Advanced Grant from the European Research Council. The work has been published in the Nature Communications journal.

Principles behind gravity-mediated entanglement were experimentally demonstrated in a simulation using photons, providing new insights into the nature of gravity.

Researchers are making significant progress in the field of quantum gravity, aiming to reconcile Einstein’s theory of gravity with quantum mechanics. Recent experiments demonstrate the principles of gravity-mediated entanglement using photons, a breakthrough in testing theories like string theory and loop quantum gravity. These experiments could transform our understanding of the universe and support future theoretical frameworks.

Quantum Gravity Research Advances

Researchers from Princeton University, University of California Santa Barbara, University of Basel, and ETH Zurich have discovered new applications for nitrogen vacancy (NV) centre quantum sensors in condensed matter physics. These sensors, which offer nanoscale resolution across a wide range of temperatures, have been used to measure static magnetic fields in condensed matter systems.

NV centres can probe beyond average magnetic fields, enabling high precision noise sensing in diverse systems. They offer several advantages over other nanoscale probes, including the ability to probe both static and dynamic properties in a momentum and frequency-resolved way.

Condensed matter physics is a field that studies the physical properties of condensed phases of matter, such as solids and liquids. Recently, researchers from Princeton University, University of California Santa Barbara, University of Basel, and ETH Zurich have discovered new opportunities in this field for nanoscale quantum sensors, specifically nitrogen vacancy (NV) centre quantum sensors. These sensors offer unique advantages in studying condensed matter systems due to their quantitative, noninvasive, physically robust nature, and their ability to offer nanoscale resolution across a wide range of temperatures.

In physics, nonreciprocity occurs when a system’s response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which essentially means that a system’s processes observed as they evolve over time will be different compared to those processes observed on rewind.
