▼a A many-body electron system in two dimensions at high magnetic field hosts a diverse set of electron ground states. Many of these ground states have been well understood for years, yet some continue to challenge researchers. The nu = 5/2 fractio |

▼a Hydrostatic pressure is a widely-used tool that provides a great deal of insight into condensed matter physics. By shrinking the lattice constant in crystalline systems, pressure changes the Bloch wavefunction and the band structure. As a result |

▼a With the application of pressure, we observed an unexpected result: a never-before-seen phase transition at filling factor nu = 5/2 from the fractional quantum Hall state to the nematic phase. The nematic phase is a phase characterized by sponta |

▼a There are many examples of quantum phase transitions in condensed matter, but the one we have observed at nu = 5/2 is unusual. This is a quantum phase transition which changes topological order, as the quantum Hall state is destroyed, as well as |

▼a To gain further insight into the underlying mechanism of the fractional quantum Hall state-to-nematic transition, we also studied the filling factor nu = 7/2, the closely- related cousin of nu = 5/2, under pressure. The fractional quantum Hall s |
