The so-called Casimir force or Casimir effect is a quantum mechanical phenomenon resulting from fluctuations in the electromagnetic field between two conducting or dielectric surfaces that are a short distance apart. Studies have shown that this force can be either be...

Exploring the origin of polaron formation in halide perovskites
Halide perovskites are a class of materials with an underlying structure resembling that of mineral perovskites, but with X sites occupied by halide ions, while their A and B sites are occupied by cations. These materials have various advantageous properties that make...
How does light interact with matter at extreme intensities, near the Schwinger limit?
The experimental generation of increasingly intense light beams could help to unveil new physical regimes occurring in the presence of very strong electromagnetic fields. While some progress has been made towards this goal, physicists are yet to develop a reliable...
Nonreciprocal quantum batteries exhibit remarkable capacities and efficiency
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...
A model outlining the microscopic origin of black hole entropy
Black holes are intriguing astronomical objects that have a gravitational pull so strong that it prevents any object and even light from escaping. While black holes have been the topic of numerous astrophysical studies, their origins and underlying physics remain...
The observation of a Spin Berry curvature-enhanced orbital Zeeman effect in a kagome metal
In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction.
Study sheds light on the origin of elasticity in glasses and gels
Glasses and gels are two different types of solid materials that are commonly used in a wide range of settings. Despite their markedly different compositions, these distinct materials share some similar properties, for instance, they exhibit rigidity without a...
The BREAD Collaboration is searching for dark photons using a coaxial dish antenna
Approximately 80% of the matter in the universe is predicted to be so-called "dark matter," which does not emit, reflect, or absorb light and thus cannot be directly detected using conventional experimental techniques.
Generating graph states of atomic ensembles via photon-mediated entanglement
Graph states, a class of entangled quantum states that can be represented by graphs, have been the topic of numerous recent physics studies, due to their intriguing properties. These unique properties could make them particularly promising for quantum computing...
Demonstration of heralded three-photon entanglement on a photonic chip
Photonic quantum computers are computational tools that leverage quantum physics and utilize particles of light (i.e., photons) as units of information processing. These computers could eventually outperform conventional quantum computers in terms of speed, while also...
