Tutorial: Extracting entanglement signatures from neutron spectroscopy
Allen Scheie, Pontus Laurell, Wolfgang Simeth +2
This tutorial is a pedagogical introduction to recent methods of computing quantum spin entanglement witnesses from spectroscopy, with a special focus on neutron scattering on quan…
Pairing tendencies in the doped Kitaev-Heisenberg model
Pontus Laurell, Bradraj Pandey, Gábor B. Halász +3
We study the impact of hole-doping on the Kitaev-Heisenberg model on the honeycomb lattice. We investigate the pairing tendencies and correlation functions in the framework of a $t…
Magnetic Correlations and Pairing Tendencies of the Hybrid Stacking Nickelate Superlattice LaNiO (LaNiO/LaNiO) under Pressure
Yang Zhang, Ling-Fang Lin, Adriana Moreo +2
Motivated by the recent rapid progress in high- nickelate superconductors, we comprehensively study the physical properties of the alternating bilayer trilayer stacking nickel…
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…
Dynamics and Fusion of Majorana Zero Modes in Quantum-dot based Interacting Kitaev Chains
Bradraj Pandey, Elbio Dagotto
Motivated by the recent experimental realization of a minimal Kitaev chain in quantum dot systems, we present our theoretical findings on the dynamics and fusion of MZMs at or near…
Crystalline-Symmetry-Protected Majorana Modes in Coupled Quantum Dots
Bradraj Pandey, Gonzalo Alvarez, Elbio Dagotto +1
We propose a minimalist architecture for achieving various crystalline-symmetry-protected Majorana modes in an array of coupled quantum dots. Our framework is motivated by the rece…
