The researchers discovered that a new theoretical framework to unify Hermitian and non-Hermitian physics is established by the duality between non-Hermiticity and curved spaces. A physics puzzle is resolved through a new duality. According to traditional thinking, distorting a flat space by bending it or stretching it is necessary to create a curved space. A group of scientists at Purdue University has developed a new technique for making curved spaces that also provides the answer to a physics mystery. The team has developed a method using non-Hermiticity, which occurs in all systems coupled to environments, to build a hyperbolic surface...
