Collective excitations at filling factor 5/2: The view from superspace
Published 13 Sep 2019 in cond-mat.str-el, cond-mat.mes-hall, and hep-th | (1909.06384v1)
Abstract: We present a microscopic theory of the neutral collective modes supported by the non-Abelian fractional quantum Hall states at filling factor 5/2. The theory is formulated in terms of the trial states describing the Girvin-MacDonald-Platzman (GMP) mode and its fermionic counterpart. These modes are superpartners of each other in a concrete sense, which we elucidate.
