DOI: 10.1002/mana.201900190
Abstract: We study instanton bundles E on P1×P1×P1 . We construct two different monads which are the analog of the monads for instanton bundles on P3 and on the flag threefold F(0, 1, 2). We characterize… read more here.

DOI: 10.1007/jhep07(2021)205
Abstract: Abstract In perturbative amplitudes in quantum field theory and string field theory, Cutkosky rule expresses the anti-hermitian part of a Feynman diagram in terms of sum over all its cut diagrams, and this in turn… read more here.

DOI: 10.1021/acs.jctc.2c00124
Abstract: A combined approach that uses the vibrational configuration interaction (VCI) and semiclassical instanton theory was developed to study vibrational tunneling spectra of molecules with multiple wells in full dimensionality. The method can be applied to… read more here.

DOI: 10.1021/acs.jctc.8b00068
Abstract: Instanton theory is an established method to calculate rate constants of chemical reactions including atom tunneling. Technical and methodological improvements increased its applicability. Still, a large number of energy and gradient calculations is necessary to… read more here.
