Time crystals are time-periodic self-organized structures postulated by Frank Wilczek in
2012. While the original concept was strongly criticized, it stimulated at the same time an …

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

Some subtleties and apparent difficulties associated with the notion of spontaneous
breaking of time-translation symmetry in quantum mechanics are identified and resolved. A …

Advances in artificial intelligence (AI) are fueling a new paradigm of discoveries in natural
sciences. Today, AI has started to advance natural sciences by improving, accelerating, and …

Optical metasurfaces with high-quality-factor resonances and selective chirality
simultaneously are desired for nanophotonics. Here, an all-dielectric planar chiral …

'Der Kopf, so gesehen, hat mit dem Kopf, so gesehen, auch nicht die leiseste Ahnlichkeit (...)
Der Aspektwechsel.“Du würdest doch sagen, dass sich das Bild jetzt gänzlich geändert hat!” …

Time crystals are periodic states exhibiting spontaneous symmetry breaking in either time-
independent or periodically-driven quantum many-body systems. Spontaneous modification …

Abstract Models with non-minimal Higgs sectors represent a mainstream direction in
theoretical exploration of physics opportunities beyond the Standard Model. Extended scalar …

Thermoelectric effects in metals are typically small due to the nearly perfect particle–hole
symmetry around their Fermi surface. Furthermore, thermo-phase effects and linear …

Phase transitions--changes between different states of organization in a complex system--
have long helped to explain physics concepts, such as why water freezes into a solid or …
