A team of international researchers successfully controlled the quantum states of matter at ultrafast time scales and its chemical properties with extreme precision using light in the extreme ultraviolet. The technique was demonstrated on helium atoms, enabling the enhancement of selected quantum processes while suppressing others.
Researchers have identified a shared genetic mechanism driving the emergence of similar traits in distantly related plants with prickles. The study reveals that mutations in a specific gene can lead to prickle loss in various species, including crops like eggplants and rice.
Scientists at Tsinghua University and TU Wien have created a time crystal made of giant Rydberg atoms, exhibiting spontaneous symmetry breaking and oscillating light absorption. This breakthrough deepens our understanding of the time crystal phenomenon, offering potential applications in sensors.
The research team created a mathematical model showing that no clock can have both infinite energy and perfect time resolution, setting limits to quantum computer capabilities. This realization impacts the speed and reliability of quantum computers, as current accuracy is limited by other factors.
A team of scientists calculated that most of the Moon's permanently shadowed regions are younger than previously estimated and contain relatively young deposits of water ice. The findings suggest that current estimates for cold-trapped ices are too high, which could impact future missions to the Moon.
Researchers from Kyoto University have demonstrated the thermal quantum Mpemba effect in a wide range of initial conditions, where hotter quantum systems cool faster than initially colder ones. The team used a quantum dot connected to a heat bath and observed anomalous thermal relaxation at later times.
Researchers have developed a novel air-laser-based standoff Raman spectrometer with high temporal and frequency resolutions. The device enables remote detection of chemical species in real time, monitoring their rovibronic levels and populations in the frequency domain.
Researchers at CUNY Graduate Center explore how particles and cells give rise to large-scale dynamics that we experience as the passage of time. They found that the arrow of time emerges from simple interactions between pairs of neurons, not large groups. This discovery has implications for physics, neuroscience, and biology.
Researchers at NYU Tandon School of Engineering propose a paradigm to solve the problem of inferring collective size from individual behaviors. By observing self-propelled Vicsek particles, they show that the time rate of growth of mean square heading is sufficient to predict the number of particles under particular parameters.
Researchers at University of Innsbruck discover that digital quantum simulation can retain controlled Trotter errors for local observables, reducing the number of required gate operations. This breakthrough makes digital quantum simulation more accessible to current day quantum devices.
