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…
superconductivity of composite bosons and the fractional quantum Hall effect
Ajit C. Balram, J. K. Jain, Maissam Barkeshli
The topological -wave pairing of composite fermions, believed to be responsible for the 5/2 fractional quantum Hall effect (FQHE), has generated much exciting physics. Motivated…
Charge and spin textures of Ising quantum Hall ferromagnet domain walls
Jeroen Danon, Ajit C. Balram, Samuel Sánchez +1
We investigate the charge and spin structures associated with arbitrary smooth polarization textures in Ising (integer) quantum Hall ferromagnets. We consider the case where the tw…
Elementary Excitations in Fractional Quantum Hall Effect from Classical Constraints
Bo Yang, Ajit C. Balram
Classical constraints on the reduced density matrix of quantum fluids in a single Landau level, termed as local exclusion conditions (LECs) [B. Yang, arXiv:1901.00047], have recent…
Prediction of a non-Abelian fractional quantum Hall state with -wave pairing of composite fermions in wide quantum wells
William N. Faugno, Ajit C. Balram, Maissam Barkeshli +1
We theoretically investigate the nature of the state at quarter filled lowest Landau level and predict that, as the quantum well width is increased, a transition occurs from the co…
Parton construction of particle-hole-conjugate Read-Rezayi parafermion fractional quantum Hall states and beyond
Ajit C. Balram, Maissam Barkeshli, Mark S. Rudner
The Read-Rezayi (RR) parafermion states form a series of exotic non-Abelian fractional quantum Hall (FQH) states at filling . Computationally, the wave functions of the…
Current-induced gap opening in interacting topological insulator surfaces
Ajit C. Balram, Karsten Flensberg, Jens Paaske +1
Two-dimensional topological insulators (TIs) host gapless helical edge states that are predicted to support a quantized two-terminal conductance. Quantization is protected by time-…
