Abstract
We propose controlled splay of artificial columnar defects in cuprate superconductors as a strategy to enhance transport properties in a field compared to parallel columns. The theory predicts a new ‘‘splayed glass’’ phase characterized by a reduced flux creep, an entangled ground state, and an astronomically slow response to an applied transverse field.Keywords
