Understanding the interactions between quantum physics and gravity within a black hole is one of the thorniest problems in physics, but quantum computers could soon offer an answer
Physicists have simulated strange objects from string theory to determine what they look like – if they exist, they could be mistaken for a black hole when imaged from very far away
Condensed matter is a huge field of physics that gets less attention than it deserves. We must show people its subtle magic if we are to draw in a diverse set of researchers for the next generation, says Felix Flicker
A 2021 paper has got physicists discussing whether our inability to use classical physics to describe reality on a quantum scale is a human failing - and what proof is necessary to show that the world really is quantum mechanical, says Chanda Prescod-Weinstein
Energetic quasiparticles possess a collection of quantum characteristics that operate in a particle-like way in superconducting nanostructures, and they can undergo relaxation by involving many cascaded interactions between electrons, phonons and Cooper pairs. These interactions are significant to the performance of devices such as qubits or photon detectors, yet they remain to be well understood via quasiparticle regulated experiments. Typically, such experiments have incorporated solid-state tunnel junctions with a fixed tunnel barrier.
An object made of hundreds of atoms exhibits a quantum property normally only associated with very small objects
The DarkSide experiment is an ambitious research effort aimed at detecting dark matter particle interactions in liquid argon using a dual-phase physics detector located at the underground Gran Sasso National Laboratory. These interactions could be observed by minimizing background signals, and this could be possible thanks to the remarkable discrimination power of the scintillation pulse of liquefied argon in the DarkSide-50 detector, which can separate nuclear recoil events associated with these interactions from more than 100 million electronic recoil events linked to radioactive background.
Ultralight dark matter particles that behave like waves, called axions, seem to be a better match for gravitational lensing measurements than more traditional explanations for dark matter
