High-order connected moments expansion for the Rabi Hamiltonian
(De Gruyter, 2011-12-03)
We analyze the convergence properties of the connected moments expansion (CMX) for the Rabi Hamiltonian. To this end we calculate the moments and connected moments of the Hamiltonian operator to a sufficiently large order. ...
Prony's method and the connected-moments expansion
(IOP Publishing, 2013-01)
We show that Prony's method provides the full solution to the nonlinear equations of the connected-moments expansion (CMX). Knowledge of all the parameters in the CMX ansatz is useful for the analysis of the convergence ...
Seismic performance of moment connections in steel moment frames with HSS columns
(Techno Press, 2017)
The use of Hollow Structural Sections (HSS) provides an alternative for steel buildings in seismic zones, with the advantage over WF columns that the HSS columns have similar resistance along both axes and enhanced performance ...
Numerical study on cyclic response of end-plate biaxial moment connection in box columns
(MDPI, 2020)
The 2008 Wenchuan-China earthquake showed the importance of considering the bidirectional seismic action as a cause of failure in column hinge mechanisms. Subsequently, the large 2011 Tohoku-Japan earthquake revealed that ...
