Abstract

Further experiments showed the incorrectness of proposed interpretation. We have studied an in-plane resonant photo-response of an integer quantum Hall system in which time-reversal and parity symmetries are broken. The response of initially homogeneous system exhibits a complicate spatial structure sensitive to the system macroscopic sizes. Conceptually, the effect is explained by the large-scale quantum entanglement originated from an indistinguishable particle statistics. The concept is supported by the demonstration of entanglement-related transfer of information in the system interior.
