S. Lima This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-6280315/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract We investigate the influence of exchange interactions on quantum entanglement and magnon Nernst effect in the two-dimensional ferromagnet on honeycomb lattice. We analyze the effect of the variation induced on spin Nernst coefficient induced by the variation of the exchange parameters on entanglement. We use entanglement negativity as quantifier of entanglement and quantum correlations which is a useful measure to study entanglement in mixed state. Moreover, we studied the spin Nernst coefficient where we get that it tends to zero at T = 0, due to absence of thermally excited magnons at zero temperature. Simulations using Lanczos algorithm and exact diagonalization are performed for a finite size lattice and exhibit a behavior for entanglement negativity different from mean field theory.
