Towards Efficient Low-Order Hybrid Optimizer for Language Model Fine-Tuning Open
As the size of language models notably grows, fine-tuning the models becomes more challenging: fine-tuning with first-order optimizers (e.g., SGD and Adam) requires high memory consumption, while fine-tuning with a memory-efficient zeroth-…

Strongly enhanced shift current at exciton resonances in a noncentrosymmetric wide-gap semiconductor Open
Excitons are fundamental quasiparticles that are ubiquitous in photoexcited semiconductors and insulators. Despite causing a sharp and strong photoabsorption near the interband absorption edge, charge-neutral excitons do not yield photocur…

Large shift current via in-gap and charge-neutral exciton excitations in BN nanotubes and single BN layer Open
We perform {\it ab initio} many-body calculations to investigate the exciton shift current in small diameter zigzag BN nanotubes and also single BN sheet, using the GW plus Bethe-Salpeter equation (GW-BSE) method with the newly developed e…
