Quarterly seminars open to anyone where we talk about any subject related to scientific computation in condensed matter physics. Please register at least one day before the seminar. Once registered, you will receive information on upcoming seminars. The 13th MCSeminar Controlled bond expansion: a rank-adaptive approach for single-site DMRG and TDVP Speaker: Jheng-Wei Li (CEA Grenoble)Time & Date: 16:00 – 17:00, Jan 7 (Wednesday), 2026 (JST)Place: Zoom Traditional single-site density matrix renormalization group (DMRG) does not allow bond expansion; multi-site DMRG does but at much higher computational costs. For matrix product states (MPS), we present a controlled bond expansion (CBE) algorithm that yields two-site accuracy at single-site costs.Given an MPS, $\Psi$, with a confined … Continue reading Model Calculation Seminars
