- Abstract summary: We introduce Stark time crystals based on a type of localization that is created in the absence of any spatial disorder.
We argue that Stark time crystals constitute a phase of matter coming very close to the original idea and exhibit a symmetry breaking in space and time.

- Abstract: The compelling original idea of a time crystal has referred to a structure
that repeats in time as well as in space, an idea that has attracted
significant interest recently. While obstructions to realize such structures
became apparent early on, focus has shifted to seeing a symmetry breaking in
time in periodically driven systems, a property of systems referred to as
discrete time crystals. In this work, we introduce Stark time crystals based on
a type of localization that is created in the absence of any spatial disorder.
We argue that Stark time crystals constitute a phase of matter coming very
close to the original idea and exhibit a symmetry breaking in space and time.
Complementing a comprehensive discussion of the physics of the problem, we move
on to elaborating on possible practical applications and argue that the
physical demands of witnessing genuine signatures of many-body localization in
large systems may be lessened in such physical systems.

We propose a new Floquet time crystal model that responds in arbitrary multiples of the driving period.
Transitions between these time crystals with different periods give rise to a novel phase of matter that we call subspace-thermal discrete time crystals.

We study how the quantum dynamics transforms into a classical-like behaviour when conditions related with macroscopicity are met by the clock alone.
In the description of this emerging behaviour finds its place the classical notion of time, as well as that of phase-space and trajectories on it.

We report the experimental observation of such dissipative time crystalline order in a room-temperature atomic gas.
The observed limit cycles arise from the coexistence and competition between distinct Rydberg components.
The nondecaying autocorrelation of the oscillation, together with the robustness against temporal noises, indicate the establishment of true long-range temporal order.

The concept of space-evolution (or space-time duality) has emerged as a promising approach for studying quantum dynamics.
We show that temporal entanglement always follows a volume law in time.
This unexpected structure in the temporal entanglement spectrum might be the key to an efficient computational implementation of the space evolution.
