Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems.
Sub-cycle confinement and control of phase transitions in strongly correlated materials are theoretically demonstrated, potentially providing a way to investigate electron dynamics on timescales previously unattainable with these materials.
A highly precise timekeeping instrument has been adapted for the real world. The compact and robust device is smaller than its commercial counterparts and performs comparably in the laboratory and aboard a naval ship.
Frequency combs, which are important for applications in precision spectroscopy, depend on material nonlinearities for their function, which can be hard to engineer. Now an approach combining magnons and exceptional points is shown to be effective.
Quantum low-density parity-check codes are highly efficient in principle but challenging to implement in practice. This proposal shows that these codes could be implemented in the near term using recently demonstrated neutral-atom arrays.
Attosecond core-level spectroscopy is used to probe the ultrafast molecular dynamics of furan at the carbon K-edge, demonstrating its ability to simultaneously probe electronic and vibrational dynamics.
Iodide-related defects pose serious challenges to the irradiation, thermal, light or reverse-bias stabilities of perovskite solar cells. Here, the authors find that by using the iodide/polyiodide capture and confine effects of perfluorodecyl iodide interfacing with perovskites, inverted perovskite solar cells achieve much improved stabilities.
From extreme cold to strong magnets and high pressures, the Synergetic Extreme Condition User Facility (SECUF) provides conditions for researching these potential wonder materials.
Sub-cycle confinement and control of phase transitions in strongly correlated materials are theoretically demonstrated, potentially providing a way to investigate electron dynamics on timescales previously unattainable with these materials.
We highlight the vibrant discussions on quantum computing and quantum algorithms that took place at the 2024 American Physical Society March Meeting and invite submissions that notably drive the field of quantum information science forward.
By suppressing questions they considered too ‘philosophical’, post-war physicists created an unquestioning orthodoxy that influences science to this day.
Ranga Dias sued his university, in part, for allegedly conducting a biased investigation, which found he had committed extensive scientific misconduct.
