Artificial gravity field, astrophysical analogues, and topological phase transitions in strained topological semimetals

Condensed matter: Creating black holes in materials A material that mimics the behavior of a black hole is developed by researchers in China and Singapore. Yugui Yao from the Beijing Institute of Technology and colleagues show that mechanical strain in a material known as Dirac semimetal can imitate...
