晶体究竟只是一种数学上的假设、还是真的存在呢?自打诺贝尔得主弗朗克·韦尔切克于2012年首次提出时间晶体概念以来,物理学家就一直在这个问题上争论不休,韦尔切克称,这些假想中的晶体可以呈现出周期性的运动状态,如在低能量状态(又称基态)下沿着环形轨道运动等。而从理论上来说,处于基态的物体所具备的能量是根本不够让其运动起来的。于是在他提出该理念之后的几年中,其他物理学家纷纷给出了时间晶体不可能存在 Is crystal really just a mathematical assumption or is it true? Physicists have been debating this issue ever since the Nobel laureate Franco Vercek first proposed the concept of time crystals in 2012, Verceck said these imaginary crystals can exhibit periodic motions, such as moving along orbits in a low-energy state (also known as ground state). Theoretically speaking, the energy of the object in the ground state is not enough to make it move. So a few years after he came up with the idea, other physicists gave time crystals impossible
