Quantum tomography is a process that involves the reconstruction and characterization of a quantum state using a series of collected measurements. Over the past few years, many physicists have been trying to use this process ...
In their latest study, a team led by Tracy Northup at the Department of Experimental Physics unveils the successful creation of a levitated nanomechanical oscillator with an ultra-high quality factor, significantly surpassing ...

Too much background noise is usually guaranteed to disrupt work. But physicists have developed a micro-scale engine–made from a glass bead–that can not only withstand the distracting influence of noise, but can harness ...

The cosmic optical background (COB) is the visible light emitted by all sources outside of the Milky Way. This faint glow of light, which can only be observed using very precise and sophisticated telescopes, could help astrophysics ...
For many years, most astrophysical models assumed that planets beyond our solar system, known as exoplanets, are heated at similar depths by their host stars (i.e., stars like the sun around which planetary systems are formed). ...
Primordial black holes (PBHs) are fascinating cosmic bodies that have been widely investigated by astrophysicists worldwide. As suggested by their name, these are black holes believed to have appeared in the universe's early ...
Topological wave structures are wave patterns that exhibit specific topological properties, or in other words, properties that remain unvaried under smooth deformations of a physical system. These structures, such as vortices ...
Five independent teams of researchers have reviewed the work and claims made by a group at the National Ignition Facility (NIF) who announced in December 2022 that they had achieved the first laser-powered fusion reaction ...
A small team of astrophysicists affiliated with several institutions in China has found evidence that suggests if wormholes are real, they might magnify light by 100,000 times. In their paper published in the journal Physical ...
Excitations in solids can also be represented mathematically as quasiparticles; for example, lattice vibrations that increase with temperature can be well described as phonons. Mathematically, also quasiparticles can be described ...
