Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

The discussion begins casually, but the moment scientific topics arise, everything falls apart. One speaker tries to defend ideas with no grasp of the principles involved. Each clarification only ...

The race to release world models is on as AI image and video generation company Runway joins an increasing number of startups and Big Tech companies by launching its first one. Dubbed GWM-1, the model ...

Welcome to the Department of Physics and Astronomy at the University of Delaware, where the pursuit of scientific discovery and innovation meets cutting-edge research and academic excellence. Our ...

Passive, lossy materials with positive index at real frequencies can be used to realize optical antimatter under complex frequency excitation. Our approach enables arbitrary complex \(\epsilon ,\,\mu\ ...

Theoretical physics is the development of mathematical formalisms and computational protocols for describing all aspects of objects found in the world around us and their interaction. This can involve ...

Slow spectroscopy The experiment was able to detect the extremely faint, long-timescale signals emitted by luminescent materials. This material is illuminated by a laser and the faint signals long ...

Working in the dark Because silver iodide is photosensitive, the scientists performed their experiments largely in the dark, with only dim red lighting used. (Courtesy: TU Wien) Silver iodide crystals ...
