Science Daily: Ultrafast and coupled: Atomic vibrations in the quantum material boron nitride
Each instantiation and full specialization of the std::atomic template defines an atomic type. If one thread writes to an atomic object while another thread reads from it, the behavior is well-defined (see memory model for details on data races). In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by std::memory ...
Constructs a new atomic variable. ... 2) Initializes the underlying object with desired. The initialization is not atomic. 3) Atomic variables are not CopyConstructible.
Explanation Objects of atomic types are the only objects that are free from data races; that is, they may be modified by two threads concurrently or modified by one and read by another. Each atomic object has its own associated modification order, which is a total order of modifications made to that object.

Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental ...
