An important part of physics research is examining why theoretical calculations and experimental results sometimes don’t match. A recent experiment in Germany studied the helium-4 nucleus, also known as an alpha particle. Helium-4 consists of only two protons and two neutrons, making it relatively easy to describe using theoretical calculations. This makes it useful for […]

Using two optically-trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and non-linear dynamic driven by non-reciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating non-conservative interactions.

If you make a material thinner and thinner, at a certain point it undergoes a seemingly miraculous transformation: A two-dimensional material that consists of only one or two layers of molecules sometimes has completely different properties than the same material when it is thicker.

The trunk of an elephant is among the versatile appendages in the animal kingdom. Now a research team has shown that most of its dexterity can be reproduced with a model using just three “muscles.” And they built a physical model to do just that. The findings are published in the journal Physical Review Letters. […]

A search for “air fryer recipe” on most social media platforms likely returns a flood of food videos touting quick and easy meal ideas. The market touts these devices as a convenient, clean, quick way to heat and crispen food, that offers a typically healthier option to using conventional deep fryers.

Structured light can significantly enhance information capacity, due to its coupling of spatial dimensions and multiple degrees of freedom. In recent years, the combination of structured light patterns with image processing and machine intelligence has shown vigorous development potential in fields such as communication and detection.

A dissipative time crystal is a phase of matter characterized by periodic oscillations over time, while a system is dissipating energy. In contrast with conventional time crystals, which can also occur in closed systems with no energy loss, dissipative time crystals are observed in open systems with energy freely flowing in and out of them. […]

Atomic nuclei come in different shapes, varying from football-like (“prolate”) to pancake-like (“oblate”). Prolate and oblate shapes have different moments of inertia. This is a body’s resistance to having its speed of rotation altered by an external force. Atomic nuclei having different shapes with different moments of inertia implies that it takes different amounts of […]
