tart szemináriumot "Unconventional magnetotransport in Weyl semimetals"
címmel

Az előadás összefoglalója:

In this talk I will review some transport properties in Weyl semimetals
that are connected to the geometrical properties of the bandstructure in
these systems, like the (now) famous B^2 dependent negative
magnetoresistance, observed in these materials[1]. Within this context, I
will describe other transport phenomena that were supposed not to be
allowed in these materials[2], like the linear magnetochiral effect[3]. I
will describe how this effect also allows for the presence of second order
non linear optical responses in inversion symmetric Dirac semimetals under
the presence of an external magnetic field[4].
