Interaction-induced oscillations of the tunneling density of states in a non-quantizing magnetic field

TL;DR

This paper investigates how electron-electron interactions cause novel oscillations in the tunneling density of states in a disordered 2D electron gas under a non-quantizing magnetic field, revealing a new quantum phenomenon.

Contribution

It demonstrates that interactions induce a new type of oscillations in the tunneling density of states, distinct from standard quantum oscillations, in a non-quantizing magnetic field.

Findings

Interaction causes oscillations with cyclotron quantum period

Oscillations occur without standard de Haas--van Alphen effect

Reveals a new quantum oscillation phenomenon

Abstract

We study tunneling into interacting disordered two-dimensional electron gas in a non-quantizing magnetic field, which does not cause the standard de Haas-- van Alphen oscillations. Interaction induces a new type of oscillations in the tunneling density of states with the characteristic period of cyclotron quantum.
