A time crystal, as originally proposed in 2012, is a new state of matter in which the particles are in continuous oscillatory motion. Time crystals break time-translation symmetry. Discrete time crystals do so by oscillating ...
In quantum electrodynamics, the choice of gauge (i.e. specific mathematical formalism used to regulate degrees of freedom) can greatly influence the form of light-matter interactions. Interestingly, however, the "gauge invariance" ...
In the unending effort to reduce the size of computing nodes, scientists at University of Liège, Belgium, The Hebrew University, Jerusalem, University of Padova, Italy, and University of California, Los Angeles have employed ...
(Phys.org) -- Finding new connections between different disciplines leads to new – and sometimes useful – ideas. That’s exactly what happened when scientists in the Department of Physics, Queens College, ...
A scientist might want to do cartwheels upon making a discovery, but this time the discovery itself relies on cartwheels.
