Boosting the effective performance of massively parallel tensor network state algorithms on hybrid CPU-GPU based architectures via non-Abelian symmetries
Andor Menczer, Örs Legeza
We present novel algorithmic solutions together with implementation details utilizing non-Abelian symmetries in order to boost the current limits of tensor network state algorithms…
Quantum sensor in a single layer van der Waals material
Rohit Babar, Gergely Barcza, Anton Pershin +8
Point defect qubits in semiconductors have demonstrated their outstanding high spatial resolution sensing capabilities of broad multidisciplinary interest. Two-dimensional (2D) sem…
How creating one additional well can generate Bose-Einstein condensation
Mihály Máté, Örs Legeza, Rolf Schilling +2
The realization of Bose-Einstein condensation in ultracold trapped gases has led to a revival of interest in that fascinating quantum phenomenon. This experimental achievement nece…
Ground State of the Fe(II)-porphyrin Model System Corresponds to the Quintet State: A DFT and DMRG-based Tailored CC Study
Andrej Antalík, Dana Nachtigallová, Rabindranath Lo +6
Fe(II)-porphyrins (FeP) play an important role in many reactions relevant to material science and biological processes, due to their closely lying spin states. However, this small…
Massively parallel quantum chemical density matrix renormalization group method
Jiří Brabec, Jan Brandejs, Karol Kowalski +3
We present, to the best of our knowlegde, the first attempt to exploit the supercomputer platform for quantum chemical density matrix renormalization group (QC-DMRG) calculations.…
Ab initio theory of negatively charged boron vacancy qubit in hBN
Viktor Ivády, Gergely Barcza, Gergő Thiering +5
Highly correlated orbitals coupled with phonons in two-dimension are identified for paramagnetic and optically active boron vacancy in hexagonal boron nitride by first principles m…
