Universality of long-wavelength behavior of composite-fermion Fermi liquid
Aamir A. Makki, Mytraya Gattu, J. K. Jain
A recent article evaluated the long-wavelength behavior of the projected static structure factor of the composite-fermion (CF) liquid within the zeroth-order microscopic theory and…
Probing fractional quantum Hall effect by photoluminescence
Aamir A. Makki, Mytraya Gattu, J. K. Jain
The recent discovery of fractional quantum anomalous Hall (FQAH) states - fractional quantum Hall (FQH) states realized without an external magnetic field - in twisted transition-m…
Exploring the nature of the emergent gauge field in composite-fermion metals: A large-scale microscopic study
Amogh Anakru, Mytraya Gattu, Ajit C. Balram +4
Field theories of the composite-fermion (CF) metal model it as a Fermi sea of composite fermions coupled to an emergent gauge field. Within a random phase approximation, these theo…
Interplay of superconducting, metallic, and crystalline states of composite fermions at in wide quantum wells
Ajit C. Balram, Anirban Sharma, J. K. Jain
Evidence for developing fractional quantum Hall effect (FQHE) at filling fraction and has recently been reported in wide GaAs quantum wells [Wang \emph{et al.}, PR…
Molecular anyons in fractional quantum Hall effect
Mytraya Gattu, J. K. Jain
One of the profound consequences of the fractional quantum Hall (FQH) effect is the notion of fractionally charged anyons. In spite of extensive experimental study, puzzles remain,…
Unlocking new regimes in fractional quantum Hall effect with quaternions
Mytraya Gattu, J. K. Jain
We demonstrate that formulating the composite-fermion theory of the fractional quantum Hall (FQH) effect in terms of quaternions greatly expands its reach and opens the door into m…
