• Modeling swelling effects during coffee extraction with smoothed particle hydrodynamics 

  Mo, C.; Navarini, F.; Ellero, M.; Liverani, F.S. (2022-04-01)

  It is commonly assumed that coffee particles swell during filtration, but it has not been clarified how different degrees of swelling affect the extraction. In this article, we propose a grain swelling model to investigate ...

• Time Dynamics in Quantum Field Theory Systems 

  LIll, S. (2022-12-23)

  In this doctoral thesis, we develop and investigate new mathematical tools that are intended to allow for a rigorous description of non–perturbative quantum field theory (QFT) dynamics. Here, the term QFT is to be understood ...

• Implementing Bogoliubov Transformations Beyond the Shale-Stinespring Condition 

  LIll, S. (2022-04-28)

  We provide two extensions of a dense subspace of Fock space, such that Bogoliubov transformations become implementable on them, even though they violate the Shale-Stinespring condition, so they are not implementable on ...

• Extended State Space for Describing Renormalized Fock Spaces in QFT 

  LIll, S. (2022-06-04)

  In quantum field theory (QFT) models, it often seems natural to use, instead of wave functions from Fock space, wave functions that are not square-integrable and have prefactors involving divergent integrals (known as ...

• On the interfacial lithium dynamics in Li7La3Zr2O12:poly(ethylene oxide) (LiTFSI) composite polymer-ceramic solid electrolytes under strong polymer phase confinement 

  Rincón, M.; García, F.; Cortés, H.E.; Carrasco, J.; Akhmatskaya, E. (2022-05-27)

  A better molecular-level understanding of Li+ diffusion through ceramic/polymer interfaces is key to designing high-performance composite solid-state electrolytes for all-solid-state batteries. By considering as a case ...
