Efficient and Scalable Calculation of Complex Band Structure using Sakurai-Sugiura Method
Shigeru Iwase, Yasunori Futamura, Akira Imakura +2
Complex band structures (CBSs) are useful to characterize the static and dynamical electronic properties of materials. Despite the intensive developments, the first-principles calc…
Contour integral method for obtaining the self-energy matrices of electrodes in electron transport calculations
Shigeru Iwase, Yasunori Futamura, Akira Imakura +3
We propose an efficient computational method for evaluating the self-energy matrices of electrodes to study ballistic electron transport properties in nanoscale systems. To reduce…
Efficient implementations of the modified Gram-Schmidt orthogonalization with a non-standard inner product
Akira Imakura, Yusaku Yamamoto
The modified Gram-Schmidt (MGS) orthogonalization is one of the most well-used algorithms for computing the thin QR factorization. MGS can be straightforwardly extended to a non-st…
Simulations of core-collapse supernovae in spatial axisymmetry with full Boltzmann neutrino transport
Hiroki Nagakura, Wakana Iwakami, Shun Furusawa +6
We present the first results of our spatially axisymmetric core-collapse supernova simulations with full Boltzmann neutrino transport, which amount to a time-dependent 5-dimensiona…
