High Energy Theory Seminar

Charge transport near quantum critical points partly occur in phases with spontaneously broken symmetries. In an effective field theory approach, this transport can be described in a hydrodynamic theory with Goldstone modes encoding the broken symmetries. The symmetry can be restored gradually, modelling properties in the quantum critical region. I will discuss the case of broken translations (fluctuating stripes), partly in the presence of a high magnetic field (magnetophonons).
