Inner workings of fractional quantum Hall parent Hamiltonians: A matrix product state point of view
Matheus Schossler, Sumanta Bandyopadhyay, Alexander Seidel
We study frustration-free Hamiltonians of fractional quantum Hall (FQH) states from the point of view of the matrix product state (MPS) representation of their ground and excited s…
Axion-matter coupling in multiferroics
Henrik S. Røising, Benjo Fraser, Sinéad M. Griffin +4
Multiferroics (MFs) are materials with two or more ferroic orders, like spontaneous ferroelectric and ferromagnetic polarizations. Such materials can exhibit a magnetoelectric effe…
Classification of superconducting orders in nonhermitian systems
Sumanta Bandyopadhyay, Alexander Balatsky
We have investigated the effects of nonhermiticity on superconducting states. We have shown the definition of the time-ordered product in the Green's function requires the introduc…
Quantum Pairing Time Orders
A. V. Balatsky, P. O. Sukhachov, S. Bandyopadhyay
We propose the concept of the time-independent correlators for the even- and odd-frequency pairing states that can be defined for both bosonic and fermionic quasiparticles. These c…
Local two-body parent Hamiltonians for the entire Jain sequence
Sumanta Bandyopadhyay, Gerardo Ortiz, Zohar Nussinov +1
Using an algebra of second quantized operators, we develop local two-body parent Hamiltonians for all unprojected Jain states at filling factor , with integer ,…
Composite fermions in Fock space: Operator algebra, recursion relations, and order parameters
Li Chen, Sumanta Bandyopadhyay, Kun Yang +1
We develop recursion relations, in particle number, for all (unprojected) Jain composite fermion (CF) wave functions. These recursions generalize a similar recursion originally wri…
Entangled Pauli Principles: the DNA of Quantum Hall Fluids
Sumanta Bandyopadhyay, Li Chen, Mostafa Tanhayi Ahari +3
A formalism is developed for the rigorous study of solvable fractional quantum Hall parent Hamiltonians with Landau level mixing. The idea of organization through "generalized Paul…
The Jain-2/5 parent Hamiltonian: structure of zero modes, dominance patterns, and zero mode generators
Li Chen, Sumanta Bandyopadhyay, Alexander Seidel
We analyze general zero mode properties of the parent Hamiltonian of the unprojected Jain-2/5 state. We characterize the zero mode condition associated to this Hamiltonian via proj…
A New Class of Solutions of Combined KdV-mKdV Equation
Sumanta Bandyopadhyay
In this work, the exact solutions for combined KdV-mKdV generalized equation as a linear superposition of Jacobi elliptic functions, , . When is set to one,…
