Broken symmetries and excitation spectra of interacting electrons in partially filled Landau levels
Gelareh Farahi, Cheng-Li Chiu, Xiaomeng Liu +5
Interacting electrons in flat bands give rise to a variety of quantum phases. One fundamental aspect of such states is the ordering of the various flavours - such as spin or valley…
Visualizing Broken Symmetry and Topological Defects in a Quantum Hall Ferromagnet
Xiaomeng Liu, Gelareh Farahi, Cheng-Li Chiu +5
The interaction between electrons in graphene under high magnetic fields drives the formation of a rich set of quantum Hall ferromagnetic phases (QHFM), with broken spin or valley…
Evidence for a Monolayer Excitonic Insulator
Yanyu Jia, Pengjie Wang, Cheng-Li Chiu +19
The interplay between topology and correlations can generate a variety of quantum phases, many of which remain to be explored. Recent advances have identified monolayer WTe2 as a p…
Spectroscopy of a Tunable Moiré System with a Correlated and Topological Flat Band
Xiaomeng Liu, Cheng-Li Chiu, Jong Yeon Lee +5
Moiré superlattices created by the twisted stacking of two-dimensional crystalline monolayers can host electronic bands with flat energy dispersion in which interaction among elect…
Dirac Nodal Line and Rashba Splitting Surface States in Nonsymmorphic ZrGeTe
Yun Yen, Cheng-Li Chiu, Ping-Hui Lin +4
Dirac semimetals (DSMs) are three dimensional analogue to graphene with symmety enforced bulk Dirac nodes. Among various DSMs, ZrSiS has been attracting more interests recently, du…
Spectroscopic signatures of many-body correlations in magic angle twisted bilayer graphene
Yonglong Xie, Biao Lian, Berthold Jäck +6
The discovery of superconducting and insulating states in magic angle twisted bilayer graphene (MATBG) has ignited considerable interest in understanding the nature of electronic i…
