چکیده
Some subtleties and apparent difficulties associated with the notion of spontaneous breaking of time-translation symmetry in quantum mechanics are identified and resolved. A model exhibiting that phenomenon is displayed. The possibility and significance of breaking of imaginary time-translation symmetry is discussed.

Time Crystals
In this talk we will discuss the new idea of "Time Crystals" †. The most important idea in physics is that physics laws are governed by symmetry. Equally important is the result of symmetry breaking. A standard example of symmetry breaking is the existence of crystals: the symmetry breaking of the continuous spatial translation symmetry to the discrete spatial translation symmetry gives the var...
متن کاملLiquid crystal phases of two-dimensional dipolar gases and Berezinskii-Kosterlitz-Thouless melting
Liquid crystals are phases of matter intermediate between crystals and liquids. Whereas classical liquid crystals have been known for a long time and are used in electro-optical displays, much less is known about their quantum counterparts. There is growing evidence that quantum liquid crystals play a central role in many electron systems including high temperature superconductors, but a quanti...
متن کاملCrystals of Time
Spontaneous symmetry breaking is ubiquitous in nature. It occurs when the ground state (classically, the lowest energy state) of a system is less symmetrical than the equations governing the system. Examples in which the symmetry is broken in excited states are common—one just needs to think of Kepler’s elliptical orbits, which break the spherical symmetry of the gravitational force. But sponta...
متن کاملPre-thermal Time Crystals and Floquet topological phases without disorder
We show that both discrete and continuous time-translation symmetry can be broken in the prethermal regime of quantum systems that eventually thermalize. We prove a theorem that states that such “time crystals” persist until times that are nearly exponentially-long in the couplings and, in driven systems, the drive frequency. After this thermalization time, the time-translational symmetry break...
متن کاملFabrication of three-dimensional woodpile photonic crystals in a PbSe quantum dot composite material.
Incorporating active media into three-dimensional (3D) photonic crystals (PCs) is a useful step towards exploring the functionalities of PCs. Here we report, for the first time, on the fabrication of 3D woodpile PCs with a commercial PbSe quantum dot (QD) composite material by using the two-photon polymerization technique. The fabricated crystals possess photonic band gaps in the near-infrared ...
متن کاملAbsence of Quantum Time Crystals.
In analogy with crystalline solids around us, Wilczek recently proposed the idea of "time crystals" as phases that spontaneously break the continuous time translation into a discrete subgroup. The proposal stimulated further studies and vigorous debates whether it can be realized in a physical system. However, a precise definition of the time crystal is needed to resolve the issue. Here we firs...
