A new robotic platform to reproduce and study complex ciliary behavior
Cilia are sensory structures extending from the surface of some cells. These hair-like structures are known to contribute to the sensorimotor capabilities of various living organisms, including humans.
Study unveils limits on the extent to which quantum errors can be ‘undone’ in large systems
Quantum computers have the potential of outperforming conventional computers on some practically relevant information processing problems, possibly even in machine learning and optimization. Yet their large-scale deployment is not yet feasible, largely due to their...
Cosmic microwave background experiments could probe connection between cosmic inflation, particle physics
Various large-scale astrophysical research projects are set to take place over the next decade, several of which are so-called cosmic microwave background (CMB) experiments. These are large-scale scientific efforts aimed at detecting and studying CMB radiation, which...
A new technique to calculate the physical running of couplings in quadratic gravity
Researchers at the International School for Advanced Studies in Trieste, University of Massachusetts, and Instituto de Física Teórica at Universidade Estadual Paulista in Brazil recently introduced an alternative approach to derive the correct physical beta functions...
Exploring what happens when different spherical objects hit the water
When an object hits a body of water vertically, it is accompanied by a strong hydrodynamic force fueled by the flow of water around it, which propels it forward. The magnitude of this force is known to vary depending on the mass of the object hitting the water.
Physicists introduce method for mechanical detection of individual nuclear decays
In recent years, physicists and engineers have developed increasingly sophisticated instruments to study particles and the interactions between them with high precision. These instruments, which include particle detectors, sensors and accelerometers, could help...
Optimization algorithm successfully computes the ground state of interacting quantum matter
Over the past decades, computer scientists have developed various computing tools that could help to solve challenges in quantum physics. These include large-scale deep neural networks that can be trained to predict the ground states of quantum systems. This method is...
An optical lattice clock based on strontium atoms achieves unprecedented accuracy
Researchers at the Ye Lab at JILA (the National Institute of Standards and Technology and the University of Colorado Boulder) and University of Delaware recently created a highly precise optical lattice clock based on trapped strontium atoms. Their...
The experimental observation of a dissipative time crystal in a Rydberg gas
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...
