Time crystals represent temporal analogues of the spatial self-ordering exhibited by atomic or molecular building blocks of solid-state crystals. The pursuit of discrete time crystals (DTCs) in periodically forced Floquet closed systems has revealed how they can evade thermalization and loss of ...
Time crystals are many-body states that spontaneously break translation symmetry in time the way that ordinary crystals do in space. While experimental observations have confirmed the existence of discrete or continuous time crystals, these realizations have relied on the utilization of periodic forces o...
STIRAP consists of an efficient population transfer between two discrete quantum states of an ensemble of emitters (usually the lowest levels of Λ systems) by coherently coupling them with two radiation fields (well-controlled classical pulses) through an unpopulated intermediate state. The connection ...

14–16 In the future we can expect to see further exploration of quantum control of more complicated and realistic systems, such as polyatomic molecules, clusters, solvated particles, crystals, etc. Theoretically, the challenge lies in the numerical difficulties of quantum dynamical cal- culation...

We explore the boundary time-crystal transition at the level of quantum trajectories which result from continuous monitoring. This Letter is motivated by recent experiments [G. Ferioli, A. Glicenstein, I. Ferrier-Barbut, and A. Browaeys, Nat. Phys. 19, 1345 (2023)] realizing this many-...
Time-continuous and time-discrete (incremental) formulations are derived. A particular attention is dedicated to numerical algorithms which can be constructed from the variational formulation: for a broad class of isotropic material models, efficient predictor–corrector schemes can be derived, in the ...
It has been described that size control is achieved when the nucleation and growth processes are separated in time (Fig. 1)40. Nucleation is when a discrete particle of a new phase, a cluster, is formed in a previously single-phase system. These clusters are called nuclei in wet chemistry...
