Field-induced charge symmetry revealed by nuclear magnetic resonance in the topological insulator Bi_{2}Te_{3}
Nuclear magnetic resonance (NMR) was recently shown to measure the bulk band inversion of Bi_{2}Se_{3} through changes in the ^{209}Bi nuclear quadrupole interaction, and the corresponding tensor of the local electric field gradient was found to follow, surprisingly, the direction of the external ma...
