Ferroelectric and anomalous quantum Hall states in bare rhombohedral trilayer graphene
Felix Winterer, Fabian R. Geisenhof, Noelia Fernandez +3
Nontrivial interacting phases can emerge in elementary materials. As a prime example, continuing advances in device quality have facilitated the observation of a variety of spontan…
Ultrafast nano-imaging of dark excitons
David Schmitt, Jan Philipp Bange, Wiebke Bennecke +15
The role and impact of spatial heterogeneity in two-dimensional quantum materials represents one of the major research quests regarding the future application of these materials in…
Ultrafast dynamics of bright and dark excitons in monolayer WSe and heterobilayer WSe/MoS
Jan Philipp Bange, Paul Werner, David Schmitt +15
The energy landscape of optical excitations in mono- and few-layer transition metal dichalcogenides (TMDs) is dominated by optically bright and dark excitons. These excitons can be…
Formation of moiré interlayer excitons in space and time
David Schmitt, Jan Philipp Bange, Wiebke Bennecke +11
Moiré superlattices in atomically thin van-der-Waals heterostructures hold great promise for an extended control of electronic and valleytronic lifetimes, the confinement of excito…
Quantum cascade of new correlated phases in trigonally warped bilayer graphene
Anna M. Seiler, Fabian R. Geisenhof, Felix Winterer +5
Divergent density of states offers the unique opportunity to explore a wide variety of correlated electron physics. In the thinnest limit, this has been predicted and verified in t…
Interplay between topological protected valley and quantum Hall edge transport
Fabian R. Geisenhof, Felix Winterer, Anna M. Seiler +3
An established way of realizing topologically protected states in a two-dimensional electron gas is by applying a perpendicular magnetic field thus creating quantum Hall edge chann…
Spontaneous Gully Polarized Quantum Hall States in ABA Trilayer Graphene
F. Winterer, A. M. Seiler, A. Ghazaryan +5
Bernal-stacked multilayer graphene is a versatile platform to explore quantum transport phenomena and interaction physics due to its exceptional tunability via electrostatic gating…
Tunable quantum anomalous Hall octet driven by orbital magnetism in bilayer graphene
Fabian R. Geisenhof, Felix Winterer, Anna M. Seiler +4
The quantum anomalous Hall (QAH) effect - a macroscopic manifestation of chiral band topology at zero magnetic field - has only been experimentally realized by magnetic doping of t…
Transconductance fluctuations as a probe for interaction induced quantum Hall states in graphene
Dong Su Lee, Viera Skakalova, R. Thomas Weitz +2
Transport measurements normally provide a macroscopic, averaged view of the sample, so that disorder prevents the observation of fragile interaction induced states. Here, we demons…
