On duality between Cosserat elasticity and fractons

open access: yesSciPost Physics, 2020
We present a dual formulation of the Cosserat theory of elasticity. In this theory a local element of an elastic body is described in terms of local displacement and local orientation.

Field-orientation dependent heat capacity measurements at low temperatures with a vector magnet system [PDF]

open access: yes, 2003
We describe a heat capacity measurement system for the study of the field-orientation dependence for temperatures down to 50 mK. A “vector magnet” combined with a mechanical rotator for the dewar enables the rotation of the magnetic field without ...
