Abstract

We report on the discovering of a quantum phase which possesses neither continuous nor discrete translational symmetry. The phase emerges from the Quantum Hall state of matter and is induced by a toroidal moment which is a cross product of “built‐in” transverse electric field and tilted quantizing magnetic field. The phase is detected by the method of terahertz photo‐voltaic spectroscopy which is insensitive to the vast majority of electrons remaining in conventional Quantum Hall states. The electrons in the new phase are demonstrated to have spatially‐separated macroscopic‐scale orbitlike wavefunctions distributed over a macroscopic sample with no spatial periodicity.
