Emergence of dual axion response in condensed matter
Elina Kokurina, Dmitry Vagin, Eduardo Barredo-Alamilla +1
Recently, it was predicted that nonreciprocal magneto-electric effect in antiferromagnetic multilayered metamaterials occurs in two distinct versions. One is the conventional axion…

Complex-valued Tellegen response
Fedor Nutskii, Eduardo Barredo-Alamilla, Maxim A. Gorlach
We consider a medium exhibiting non-reciprocal magneto-electric effect known as Tellegen response captured by the equations of axion electrodynamics. Here, we investigate the impli…

Probing ultrafast magnetization dynamics via synthetic axion fields
Leon Shaposhnikov, Eduardo Barredo-Alamilla, Frank Wilczek +1
Spatial structuring of materials at subwavelength scales underlies the concept of metamaterials possessing exotic properties beyond those of the constituent media. Temporal modulat…
