Event Details

The competition of paired and nematic ground states occurring in strongly correlated systems, such as high Tc superconductors and transition metal dicalchogenides, remains poorly understood. Paired and nematic states are also known to exist in the two-dimensional electron gas. However, these phases form in different areas of the phase space and, therefore, a phase transition between them was not possible. In this talk I will discuss the observation of a pressure-driven direct phase transition between a paired fractional quantum Hall state and a nematic phase in the electron gas. The role of the pressure driving the transition and special properties of this phase transition will be discussed.
