Quantized transconductance emerges from non-symmetric quantum fluctuations: theoretical prediction

TL;DR

This paper predicts that non-symmetric quantum fluctuations can induce a quantized transconductance in multi-terminal quantum contacts, potentially enabling quantum Hall effects without traditional conditions.

Contribution

It introduces a theoretical framework showing quantum fluctuations can produce quantized transconductance, challenging conventional understanding of quantum transport phenomena.

Findings

Quantum fluctuations can lead to quantized transconductance

Quantized transconductance can occur without traditional quantum Hall conditions

Potential realization of topological quantum states without magnetic fields

Abstract

We show theoretically that weak quantum fluctuations induced by a non-symmetric electromagnetic environment may lead to a quantized transconductance of a multi-terminal quantum contact rather than to a blockade of transport in the contact. The result suggests the possibility to realize Quantum Hall phenomenology without its common ingredients and/or a topological quantum state.
