For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of ...

Ever since Einstein posited that space and time were inextricably linked, scientists have wondered where the cosmic web called spacetime comes from. When two particles are able to simultaneously and ...

State Key Laboratory of Low-Dimensional Quantum Physics, Tsinghua has the following research output in the current window (1 October 2024 - 30 September 2025) of the Nature Index. Click on Count to ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

What if the Universe – and fundamentally, space itself – were like a pile of laundry? Have one. See this laundry pile? Looks just like our universe. No? Here, have another. See it now? It’s got three ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, revealing light-like particles with a strikingly high-dimensional character. By ...

When someone mentions "different dimensions," we tend to think of things like parallel universes – alternate realities that exist parallel to our own, but where things work or happened differently.

Scientists have succeeded in conducting a new experiment that supports the existence of the long-sought-after Luttinger liquid state. How would electrons behave if confined to a wire so slender they ...

A refreshingly simple new idea has emerged in the complicated world of high energy physics. It proposes that the early universe was a one-dimensional line. Not an exploding sphere, not a chaotic ball ...
