Study proves the difficulty of simulating random quantum circuits for classical computers
Quantum computers, technologies that perform computations leveraging quantum mechanical phenomena, could eventually outperform classical computers on many complex computational and optimization problems. While some quantum computers have attained remarkable results on...
A theory of strong-field non-perturbative physics driven by quantum light
Non-perturbative interactions (i.e., interactions too strong to be described by so-called perturbation theory) between light and matter have been the topic of numerous research studies. Yet the role that quantum properties of light play in these interactions and the...
LHCb collaboration observes a doubly charged tetraquark and its neutral partner for the first time
The observation of elusive, exotic particles is the key objective of countless studies, as it could open new avenues for research, while also improving present knowledge of the matter contained in the universe and its underlying physics. The quark model, a theoretical...
A dynamic matrix with DNA-encoded viscoelasticity to support the development of organoids and other biological tissues
Over the past few decades, material scientists and chemists have been working on designing increasingly sophisticated materials for a wide range of technological and scientific applications. These materials include synthetic polymers and hydrogels that could be...
The first observation of neutrinos at CERN’s Large Hadron Collider
Neutrinos are tiny and neutrally charged particles accounted for by the Standard Model of particle physics. While they are estimated to be some of the most abundant particles in the universe, observing them has so far proved to be highly challenging, as the...
The superconducting diode effect in a device based on coupled Josephson junctions
The so-called superconducting (SC) diode effect is an interesting nonreciprocal phenomenon, occurring when a material is SC in one direction and resistive in the other. This effect has been the focus of numerous physics studies, as its observation and reliable control...
Study reveals an asymmetric dispersion of phason excitations in a skyrmion lattice
Magnetic skyrmions, statically stable magnetic quasiparticles with a topological charge, have been the focus of numerous recent studies, as they could support the development of so-called spintronics. These devices, which leverage the spin of electrons, could perform...
Study demonstrates many-body chemical reactions in a quantum degenerate gas
In recent years, physicists have been trying to attain the control of chemical reactions in the quantum degenerate regime, where de Broglie wavelength of particles becomes comparable to the spacing between them. Theoretical predictions suggest that many-body reactions...
Researchers observe ubiquitous superconductive diode effect in thin superconducting films
The so-called superconducting (SC) diode effect has recently attracted significant attention within the physics research community, due to its potential value for developing new technologies. This effect provides a key example of nonreciprocal superconductivity, as...
