Cultivating in the Indigenous Way, Eating in the National Way: Changing Food and Identity among the Malo, Southwestern Ethiopia
This article is a revised and updated version of the author’s previous article published in Japanese (Fujimoto 2019).Although teff (Eragrostis tef) is a minor cereal worldwide, it is cultivated most extensively in Ethiopia and still expanded in cultivation area. This article considers why this millet is so important in this region by analyzing the case of the Malo society in southwestern Ethiopia. Their indigenous techniques used for cultivating teff suggest that they have been cultivating it since long before the incorporation of their territory into the Ethiopian empire at the end of 19th century. However, it is also known that teff cultivation began extensively in this area no more than a half century ago. Although several factors contribute to the expansion of teff cultivation, the most important factor is the adoption of a national food item known as injera in the mid-1970s. Malo people knew about it before but did not eat it because it was strongly associated with the imperial settlers who exploited them. Following the Ethiopian revolution during 1974–1975, however, they started to enjoy injera. Currently, it is one of their most popular dietary items consumed on holidays and at markets. Not only the taste of injera but also the rising identity of the people as Ethiopians seem to be involved with the food's popularity
Possible Realization of Topological Crystalline Superconductivity with Time-Reversal Symmetry in UTe2
The recent measurement of the de Haas-van Alphen effect in the spin-triplet
superconductor UTe2 [D. Aoki et al., J. Phys. Soc. Jpn. 91, 083704 (2022)]
supports cylindrical electron and hole Fermi surfaces, which implies that UTe2
is trivial as a 3D time-reversal-invariant topological superconductor. Inspired
by this observation, we investigate the possible realization of a topological
crystalline superconductor protected by the crystalline symmetry of UTe2. We
examine Majorana surface states protected by mirror and two-fold rotational
symmetries for all symmetry-allowed odd-parity pairing states with
time-reversal symmetry and clarify the corresponding topological invariants. It
is found that topological crystalline superconductivity can be realized for all
irreducible representations of odd-parity pairing states of UTe2 even for
cylindrical Fermi surfaces.Comment: 12 pages, 7 figure
Introduction to the Supplementary Issue “Progress in African Food Culture Research”
Historically, food cultures in various parts of Africa have been nurtured through the interrelationships among people, crops and the natural environment. However, the study on food in sub-Saharan Africa so far has largely been confined to agriculture and food production; there has been little discussions on consumption patterns or eating cultures. Based on fieldwork in rural villages and literature studies, this supplementary issue focuses on the diverse food choices made by local farmers in sub-Saharan Africa in the context of crop selection and consumption and analyzes indigenous knowledge that informs farmers' choices. Moreover, it considers the relationships among the natural environment, crops and food cultures, and should facilitate future study of food cultures in sub-Saharan Africa and elsewhere
Enhanced -periodic Aharonov-Bohm Effect as a Signature of Majorana Zero Modes Probed by Nonlocal Measurements
We propose the -periodic Aharonov-Bohm (AB) effect as a nonlocal probe
of Majorana zero modes (MZMs) without the restriction of fermion parity. We
demonstrate the enhancement of the AB effect, where the topological protection
of MZMs yields amplified and robust Andreev reflection mediated by MZMs at
multiple superconductor-normal metal junctions. We investigate the influence of
trivial bound states and show that a nonlocal index enables a more explicit
distinction between the trivial and topological bound states than local probes.Comment: 9 pages, 11 figure
