Fractional Quantum Hall Effect at
Ajit C. Balram, A. Wójs
Motivated by two independent experiments revealing a resistance minimum at the Landau level (LL) filling factor , characteristic of the fractional quantum Hall effect (FQH…
Interplay between fractional quantum Hall liquid and crystal phases at low filling
Zheng-Wei Zuo, Ajit C. Balram, Songyang Pu +4
The nature of the state at low Landau-level filling factors has been a longstanding puzzle in the field of the fractional quantum Hall effect. While theoretical calculations sugges…
Fine structure of negatively charged and neutral excitons in monolayer MoS
Joanna Jadczak, Joanna Kutrowska-Girzycka, Maciej Bieniek +10
We present experimental and theoretical results on the high-quality single-layer MoS which reveal the fine structure of charged excitons, i.e., trions. In the emission spectr…
Theoretical phase diagram of two-component composite fermions in double layer graphene
William N. Faugno, Ajit C. Balram, Arkadiusz Wójs +1
Theory predicts that double layer systems realize "two-component composite fermions," which are formed when electrons capture both intra- and inter-layer vortices, to produce a wid…
Topological phase transitions in Chern insulators within three-band models
P. Potasz, B. Jaworowski, M. Kupczyński +3
We investigate topological phase transitions in Chern insulators within three-band models, focusing on the empty band and lowest band populated by spinless fermions. We consider Li…
Quantum Hall Systems: Braid groups, composite fermions, and fractional charge
Lucjan Jacak, Piotr Sitko, Konrad Wieczorek +1
The book presents the wide range of topics in two-dimensional physics of quantum Hall systems, especially fractional quantum Hall states. It starts with the fundamental problems of…
