Molecular hydrogen adsorption on MOF-210 was evaluated at the density functional theory level. The most stable H2 adsorption occurs near the acetenyls in the organic linker, but its binding energy (0.113 eV) is not sufficient to satisfy the minimum value (0.24 eV) required for practical...

Spin-dependent electron transport in a periodically stubbed quantum wire in the presence of Rashba spin-orbit interaction (SOI) is studied via the nonequilibrium Green’s function (GF) method combined with the Landauer-Büttiker formalism. By comparing with a straight Rashba quantum wire, the...

Starting from a general Hamiltonian which may undergo a quantum phase transition (QPT) with the change of a controllable parameter, we obtain a general conclusion that in a sudden quench system, when the final Hamiltonian is fixed, the behavior of the time-averaged expectation of any observable...

We carry out Density Matrix Renormalization Group (DMRG) calculations on the interchain coupling model for the quasi-one-dimensional organic ferromagnets under open boundary condition. Considering the topology of the system, the two-step DMRG technique is adopted. It is found that in the high...
