Quarter- and half-filled quantum Hall states and their competing interactions in bilayer graphene

Autor: Kumar, Ravi, Haug, André, Kim, Jehyun, Yutushui, Misha, Khudiakov, Konstantin, Bhardwaj, Vishal, Ilin, Alexey, Watanabe, Kenji, Taniguchi, Takashi, Mross, David F., Ronen, Yuval

Bilayer graphene has emerged as a key platform for non-Abelian fractional quantum Hall (FQH) states, exhibiting multiple half-filled plateaus with large energy gaps. Here, we report four unexpected quarter-filled states and complete the sequence of h

Aharonov-Bohm interference and the evolution of phase jumps in fractional quantum Hall Fabry-Perot interferometers based on bi-layer graphene

Autor: Kim, Jehyun, Dev, Himanshu, Kumar, Ravi, Ilin, Alexey, Haug, André, Bhardwaj, Vishal, Hong, Changki, Watanabe, Kenji, Taniguchi, Takashi, Stern, Ady, Ronen, Yuval

Quasi-particles in fractional quantum Hall states are collective excitations that carry fractional charge and anyonic statistics. While the fractional charge affects semi-classical characteristics such as shot noise and charging energies, the anyonic

Excess noise in the anomalous metallic phase in amorphous indium oxide

Autor: Haug, André, Shahar, Dan

More than 25 years ago, unexpected metallic behavior was discovered on the superconducting side of the superconductor-to-insulator transition. To this day, the origin of this behavior is unclear. In this work, we present resistance and broadband volt

Microwave response of the heavy-fermion superconductor CeCu2Si2

Autor: Haug, André

This thesis covers microwave experiments carried out on CeCu2Si2 as my master's project. Our data cover a range from 200 MHz to 20 GHz and 80 mK up to 25 K. Our measurements indicate that, in spite of the recent findings from specific-heat measuremen
