Hall viscosity of the composite-fermion Fermi seas for fermions and bosons [PDF]
Physical review B, 2020 The Hall viscosity has been proposed as a topological property of incompressible fractional quantum Hall states and can be evaluated as Berry curvature.

Electroweak precision tests of composite Higgs models
Journal of High Energy Physics, 2023 We study constraints on Composite Higgs models with fermion partial compositeness from electroweak precision measurements, including the 2022 W-boson mass result from the CDF collaboration.

s-Wave Paired Electron and Hole Composite Fermion Trial State for Quantum Hall Bilayers with ν=1.
Physical Review Letters, 2021 We introduce a new variational wave function for a quantum Hall bilayer at total filling ν_{T}=1, which is based on s-wave BCS pairing between electron composite fermions in one layer and hole composite fermions in the other.

Gauge fields as constrained composite bosons
Physics Letters B, 2021 We reconsider a scenario in which photons and other gauge fields appear as the composite vector bosons made of the fermion pairs that may happen with or without spontaneous violation of Lorentz invariance. The class of composite models for emergent gauge

Loop-generated neutrino masses in composite Higgs models
Journal of High Energy Physics, 2021 We present a composite scotogenic model for neutrino masses, which are generated via loops of ℤ2-odd composite scalars. We consider three different approaches to the couplings of the neutrinos (including three right-handed singlets) and the composite ...

Composite Laguerre pseudospectral method for Fokker-Planck equations
Mathematical Modelling and Analysis, 2023 A composite generalized Laguerre pseudospectral method for the nonlinear Fokker-Planck equations on the whole line is developed. Some composite generalized Laguerre interpolation approximation results are established.

Berry phase of the composite-fermion Fermi sea: Effect of Landau-level mixing [PDF]
Physical review B, 2018 We construct explicit lowest-Landau-level wave functions for the composite-fermion Fermi sea and its low-energy excitations following a recently developed approach [Pu, Wu, and Jain, Phys. Rev.

Hamiltonian theory for quantum Hall systems in a tilted magnetic field: Composite-fermion geometry and robustness of activation gaps [PDF]
Physical review B, 2018 We use the Hamiltonian theory developed by Shankar and Murthy to study a quantum Hall system in a tilted magnetic field. With a finite width of the system in the z direction, the parallel component of the magnetic field introduces anisotropy into the ...

Electroweak baryogenesis and gravitational waves in a composite Higgs model with high dimensional fermion representations [PDF]
Journal of High Energy Physics, 2020 We study electroweak baryogenesis in the SO(6)/SO(5) composite Higgs model with the third generation quarks being embedded in the 20′ representation of SO(6). The scalar sector contains one Higgs doublet and one real singlet, and their potential is given

European Physical Journal C: Particles and Fields, 2021 We introduce a unique model for a fermion-antifermion pair interacting via Dirac oscillator coupling in the presence of an external uniform magnetic field.
