Thought experiments and conservation laws: Reevaluating quantum conservation principles
Conservation laws are central to our understanding of the universe, and now scientists have expanded our understanding of these laws in quantum mechanics.

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 ...
Study proves a generalization of Bell's theorem: Quantum correlations are genuinely tripartite and nonlocal
Quantum theory predicts the existence of so-called tripartite-entangled states, in which three quantum particles are related in a way that has no counterpart in classical physics. Theoretical physicists would like to understand ...
Multiple copies of the Standard Model could solve the hierarchy problem
(Phys.org)—One of the unanswered questions in particle physics is the hierarchy problem, which has implications for understanding why some of the fundamental forces are so much stronger than others. The strengths of the ...
CP violation or new physics?
(Phys.org)—Over the past few years, multiple neutrino experiments have detected hints for leptonic charge parity (CP) violation—a finding that could help explain why the universe is made of matter and not antimatter. ...
Of Einstein and entanglement: Quantum erasure deconstructs wave-particle duality
(Phys.org)—Quantum physics presents several counterintuitive features, including entanglement, tunneling and – as demonstrated in double-slit experiments – wave-particle duality. When studying wave-particle duality, ...
Eye on ionization: Visualizing and controlling bound electron dynamics in strong laser fields
(PhysOrg.com) -- Subatomic events can be remarkably counterintuitive. Such is the case in theoretical physics when, under certain specific conditions, atoms exposed to intense infrared laser pulses remain stable rather than ...
Muon g-2 doubles down with latest measurement, explores uncharted territory in search of new physics
Physicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2.

Heaviest Schrödinger cat achieved by putting a small crystal into a superposition of two oscillation states
Even if you are not a quantum physicist, you will most likely have heard of Schrödinger's famous cat. Erwin Schrödinger came up with the feline that can be alive and dead at the same time in a thought experiment in 1935. ...

Study proves compatibility of two fundamental principles of quantum theory
Quantum theory, which was formulated in the first three decades of the twentieth century, describes a wide array of phenomena at the molecular, atomic and subatomic scales. Among its many technological applications, three ...
