The Futility of Chasing Shadows of Patriarchal Liberation: the African National Congress Women’s League (ANCWL) and Anti-Colonial Feminist Politics

open access: yesMetacritic Journal for Comparative Studies and Theory, 2018
In this paper, I combine critical feminist theories and postcolonial/decolonial feminist theories to examine the persistence of patriarchy in South Africa’s postcolonial moment.

The quantum Hall effect: A sum rule

open access: yesSurface Science, 1984
Abstract The influence of disorder on the Hall conductivity of a two-dimensional electron gas in a strong magnetic field is examined by studying the scattering of a single particle from an arbitrary potential in crossed electric and magnetic fields. The Hall current in a large system is shown to be unaffected by “islands” of disorder.

Fractional quantum Hall effect, Jain’s rule, and topological textures [PDF]

open access: yesJournal of Experimental and Theoretical Physics Letters, 2003
It is demonstrated that Jain’s rule for determining fractions in the quantum Hall effect can be obtained without recourse to the phenomenological concept of composite fermions. The possibility of existence is considered for topologically nontrivial many-electron wave functions, whose group classification gives an indication of special values of ...

Small-angle scattering in a marginal Fermi-liquid

open access: yes, 2002
We study the magnetotransport properties of a model of small-angle scattering in a marginal Fermi liquid. Such a model has been proposed by Varma and Abrahams [Phys. Rev. Lett.

Skew quantum Murnaghan-Nakayama rule [PDF]

open access: yes, 2011
In this paper, we extend recent results of Assaf and McNamara on skew Pieri rule and skew Murnaghan-Nakayama rule to a more general identity, which gives an elegant expansion of the product of a skew Schur function with a quantum power sum function in ...

Associations of Sleep and Shift Work with Osteoarthritis Risk

open access: yesArthritis Care &Research, Accepted Article.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships between circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000‐person cohort, we evaluated associations between sleep duration, sleeplessness/insomnia, and ...

Pseudogap behavior in charge density wave kagome material ScV6Sn6 revealed by magnetotransport measurements

open access: yesnpj Quantum Materials, 2023
Over the last few years, significant attention has been devoted to studying the kagome materials A V3Sb5 (A = K, Rb, Cs) due to their unconventional superconductivity and charge density wave (CDW) ordering. Recently $${{{{\rm{ScV}}}}}_{6}{{{{\rm{Sn}}}}}_{

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Relating the Hall conductivity to the many-body Chern number using Fermi’s Golden rule and Kramers–Kronig relations

open access: yesComptes Rendus. Physique
This work provides a surprisingly simple demonstration that the quantized Hall conductivity of correlated insulators is given by the many-body Chern number, a topological invariant defined in the space of twisted boundary conditions.

Rationality, the Bayesian standpoint, and the Monty-Hall problem

open access: yesFrontiers in Psychology, 2015
The Monty-Hall Problem ($MHP$) has been used to argue against a subjectivist view of Bayesianism in two ways. First, psychologists have used it to illustrate that people do not revise their degrees of belief in line with experimenters' application of ...
