* ABSTRACT

I will discuss electronic liquid crystalline phases classified by their broken symmetries. I will present a simple theory of quantum phase transition
between electronic nematic and isotropic phases. As an example of experimental signatures of electronic nematic order, I will show that metamagnetic transition can occur via the formation of an electronic nematic order. The spin-dependent Fermi surface instability gives rise to
the formation of an electronic nematic phase upon increasing the applied Zeeman magnetic field. This leads to two consecutive metamagnetic transitions that separate the nematic phase from the low-field and high-field 'isotropic' metallic phases. Possible connection to the physics of the bilayer Ruthenate, Sr3Ru2O7 will be also discussed.
