Observation of a phononic quadrupole topological insulator

Nature, 2017
The modern theory of charge polarization in solids is based on a generalization of Berry’s phase. The possibility of the quantization of this phase arising from parallel transport in momentum space is essential to our understanding of systems with ...

TOPOLOGICAL SPACES

1966
Publisher Summary This chapter defines topological spaces and the related theorems. The condition for a set A to be open in a metric space is that each point of A belongs to an open ball contained in A. A space that contains no other closed-open subset is called connected. The union of two closed sets is a closed set.
