A Supersymmetric Composite Model of Quarks and Leptons [PDF]
, 1996 We present a class of supersymmetric models with complete generations of composite quarks and leptons using recent non-perturbative results for the low energy dynamics of supersymmetric QCD. In these models, the quarks arise as composite "mesons" and the

Interlayer coherent composite Fermi liquid phase in quantum Hall bilayers [PDF]
, 2009 Composite fermions have played a seminal role in understanding the quantum Hall effect, particularly the formation of a compressible `composite Fermi liquid' (CFL) at filling factor nu = 1/2. Here we suggest that in multi-layer systems interlayer Coulomb

On Highly Composite and Similar Numbers [PDF]
Transactions of the American Mathematical Society, 1944 A (positive whole) number is called highly composite if it has more divisors than any smaller number, highly abundant if the sum of its divisors is greater than that for any smaller number, and superabundant if the sum of the reciprocals of its divisors is greater than that for any smaller number. The author uses \textit{A. E.
