Large composite fermion effective mass at filling factor 5/2 [PDF]

open access: yesNature Communications, 2023
The 5/2 fractional quantum Hall effect in the second Landau level of extremely clean two-dimensional electron gases has attracted much attention due to its topological order predicted to host quasiparticles that obey non-Abelian quantum statistics and ...

Composite vectorlike fermions

open access: yesPhysics Letters B, 2014
We study a dynamical mechanism that generates a composite vectorlike fermion, formed by the binding of an N-tuplet of elementary chiral fermions to an N-tuplet of scalars.

Hund’s rule for composite fermions [PDF]

open access: greenPhysical Review B, 1994
We consider the ``fractional quantum Hall atom" in the vanishing Zeeman energy limit, and investigate the validity of Hund's maximum-spin rule for interacting electrons in various Landau levels. While it is not valid for {\em electrons} in the lowest Landau level, there are regions of filling factors where it predicts the ground state spin correctly ...

Bipartite Composite Fermion States

open access: greenPhysical Review Letters, 2011
We study a class of ansatz wave functions in which composite fermions form two correlated "partitions." These "bipartite" composite fermion states are demonstrated to be very accurate for electrons in a strong magnetic field interacting via a short-range 3-body interaction potential over a broad range of filling factors.

Composite fermion liquid to Wigner solid transition in the lowest Landau level of zinc oxide [PDF]

open access: yesNature Communications, 2018
In two-dimensional electron systems, strong Coulomb interactions lead to the formation of new phases. Here the authors observe a transition between two of these correlated phases, a composite fermion liquid and Wigner solid, in a zinc oxide ...

Conductivity of Paired Composite Fermions [PDF]

open access: greenPhysical Review Letters, 2003
We develop a phenomenological description of the nu=5/2 quantum Hall state in which the Halperin-Lee-Read theory of the half-filled Landau level is combined with a p-wave pairing interaction between composite fermions (CFs). The electromagnetic response functions for the resulting mean-field superconducting state of the CFs are calculated and used in ...

Evidence for Topological Protection Derived from Six-Flux Composite Fermions [PDF]

open access: yesNature Communications
The composite fermion theory opened a new chapter in understanding many-body correlations through the formation of emergent particles. The formation of two-flux and four-flux composite fermions is well established.

Electroweak precision tests of composite Higgs models

open access: yesJournal of High Energy Physics, 2023
We study constraints on Composite Higgs models with fermion partial compositeness from electroweak precision measurements, including the 2022 W-boson mass result from the CDF collaboration.
