The overlap between two states differing by a small phase shift δφ is approximately equal to Thus, the state overlap is the same for a phase shift reduced by a factor 1/√N. This is the quantum ...

An exotic state of matter has been found lurking within a previous exotic state that was discovered in a magnetic compound last decade.

In their study published in the journal Nature Physics, the group used microwave ... They found that rather than seeing the expected gradual shift as a phase change occurred due to a rise in ...
