• Fine structure of large‐amplitude chorus wave packets (2014, background): “These values are consistent with a possible nonlinear generation mechanism of the fine structure of chorus related to the threshold amplitude for the nonlinear wave growth [Omura et al., 2009;Omura and Nunn, 2011; Kurita et al., 2012; Summers et al., 2013].”

• An unusual enhancement of low‐frequency plasmaspheric hiss in the outer plasmasphere associated with substorm‐injected electrons (2013, background): “Chorus waves are believed to be excited due to cyclotron resonance with anisotropic energetic electrons (a few keV to ~100 keV) injected from the plasma sheet [Kennel and Petschek, 1966; Anderson and Maeda, 1977; Meredith et al., 2001; Omura et al., 2009].”
• Modeling the evolution of chorus waves into plasmaspheric hiss (2011, background): “…are at present not well understood and remain a topic of intense research [e.g., Nunn, 1971; 1974; Nunn et al., 2009; Trakhtengerts et al., 1996, 2004; Shklyar and Matsumoto, 2009; Bespalov et al., 2010; Lampe et al., 2010; Omura et al., 2008, 2009; Schriver et al., 2010; Santolik et al., 2010].”
• Electron losses from the radiation belts caused by EMIC waves (2014, background): “Although, particularly, chorus waves are known to be highly nonlinear due to their short-duration rising tone frequency structure [e.g., Omura et al., 2009; Santoĺık et al., 2014], it is not yet computationally feasible to simulate chorus waves using nonlinear models over the duration and spatial…”
• Resonant scattering of plasma sheet electrons leading to diffuse auroral precipitation: 2. Evaluation for whistler mode chorus waves (2011, background): “[6] Nonlinear wave growth theories have also been developed to better understand the generation process and wave characteristics of chorus emissions [e.g., Nunn et al., 1997, 2009; Omura et al., 2008, 2009].”
• Three‐dimensional electron radiation belt simulations using the BAS Radiation Belt Model with new diffusion models for chorus, plasmaspheric hiss, and lightning‐generated whistlers (2014, background): “In view of the fact that chorus interactions are highly nonlinear [e.g., Trakhtengerts, 1999; Nunn et al., 1997; Omura et al., 2009], quasi-linear theory is surprisingly good at reproducing the observed variations in electron flux.”
