UNUSUAL ROOM

One of the outstanding problems facing applied holography is the development of a complete understanding of how the traditional Fermi surfaces of condensed matter physics are realized in the bulk. Whilst the general problem is very hard, in this talk I shall describe a regime in which progress can be made. In the presence of a strong magnetic field the dynamics of fermions undergoes a dimensional reduction and we are able to use Coleman’s classic technique of bosonization. This allows us to obtain a description of the Landau level physics of the boundary theory in terms of a `star’ of gravitating sine-Gordon kinks in the bulk.
