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…
