Further fundamental bounds on the Hall effect in three-dimensional metamaterials
Christian Kern, Graeme W. Milton
We consider the problem of bounding the effective nonreciprocal properties of metamaterials. Recently, significant progress was made by showing that this problem can be reduced to…

A rediscovery of stiff pentmodes. A comment on "High bulk modulus pentamodes: the three-dimensional metal water"
Graeme W. Milton
We bring attention to the fact that the claim of Brambilla et.al. [Extreme Mechanics Letters 74 (2025) 102267; arXiv:2406.14502] of discovering a novel design for pentamode materia…

Limits to the Hall effect and other nonreciprocal effects in three-dimensional metamaterials
Christian Kern, Graeme W. Milton
Metamaterials can exhibit exotic nonreciprocal properties, yet corresponding fundamental limits and design blueprints achieving them are largely unexplored. Here, we derive compreh…
