Physicists have come up with the mind-boggling concept of a time crystal. This intriguing proposal, which is based on the notion of broken time-translation symmetry, might open up a whole new field of research.

Nonlocal quantum computing theory and Poincare cycle in spherical states
Four new fundamental nonlocal quantum computing diagonal operator-state relations are derived which model the interaction between two adjacent atoms of an entangled atomic chain. Each atom possesses
Quantum interferences revealed by neutron diffraction accord with a macroscopic-scale quantum-theory of ferroelectrics KH2(1−ρ)D2ρPO4
Abstract Neutron diffraction by single-crystals KH2(1−ρ)D2ρPO4 at 293 K reveal quantum interferences consistent with a static lattice of entangled proton-deuteron scatterers. These crystals are
A neutron diffraction study of the crystal of benzoic acid from 6 to 293 K and a macroscopic-scale quantum theory of the lattice of hydrogen-bonded dimers
Abstract Measurements via different techniques of the crystal of benzoic acid have led to conflicting conceptions of tautomerism: statistical disorder for diffraction; semiclassical jumps for
Novel composites with asymmetrical elastic wave properties
Abstract The traditional structural composites are known as materials with a spatial order. The temporal order is introduced into structural composites in this paper. We theoretically describe and

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
Classical time crystals.
TLDR
This work considers the possibility that classical dynamical systems display motion in their lowest-energy state, forming a time analogue of crystalline spatial order, and exhibits models of that kind, including a model with traveling density waves.
Supersolid Discoverer’s New Experiments Show No Supersolid
The first evidence of a superfluidlike state in solid helium came from 2004 experiments that, with improvements, now find no supersolidity.
Concept of Off-Diagonal Long-Range Order and the Quantum Phases of Liquid He and of Superconductors
This review is concerned with the concept that in a many-body system of bosons or fermions, it is possible to have an off-diagonai long-range order of the reduced density matrices in the coordinate
Space-time crystals of trapped ions.
TLDR
The proposed space-time crystals of trapped ions provide a new dimension for exploring many-body physics and emerging properties of matter and are robust for direct experimental observation.
