Magnetic phase diagram of a two-orbital model for bilayer nickelates varying doping
Ling-Fang Lin, Yang Zhang, Nitin Kaushal +4
Motivated by the recently discovered high- bilayer nickelate superconductor LaNiO, we comprehensively research a bilayer cluster for different el…
Quantum error mitigation in quantum annealing
Mohammad H. Amin, Andrew D. King, Jack Raymond +32
Quantum Error Mitigation (QEM) presents a promising near-term approach to reduce error when estimating expectation values in quantum computing. Here, we introduce QEM techniques ta…
Majorana zero modes in Y-shape interacting Kitaev wires
Bradraj Pandey, Nitin Kaushal, Gonzalo Alvarez +1
Motivated by the recent experimental realization of minimal Kitaev chains using quantum dots, we investigate the Majorana zero modes (MZM) in -shape Kitaev wires. We solve the a…
Kanamori-Moiré-Hubbard model for transition metal dichalcogenide homobilayers
Nitin Kaushal, Elbio Dagotto
Ab-initio and continuum model studies predicted that the valley transition metal dichalcogenide (TMD) homobilayers could simulate the conventional multi-orbital Hubbard model o…
Magnetic ground states of honeycomb lattice Wigner crystals
Nitin Kaushal, Nicolás Morales-Durán, Allan H. MacDonald +1
Lattice Wigner crystal states stabilized by long-range Coulomb interactions have recently been realized in two-dimensional moiré materials. We employ large-scale unrestricted Hartr…
Range of biquadratic and triquadratic Heisenberg effective couplings deduced from multiorbital Hubbard models
Rahul Soni, Nitin Kaushal, Cengiz Şen +3
We studied a multi-orbital Hubbard model at half-filling for two and three orbitals per site on a two-site cluster via full exact diagonalization, in a wide range for the onsite re…
