      We consider a heterotic version of six-dimensional Kodaira-Spencer gravity derived from the heterotic superpotential. We compute the one-loop partition function and find it can be expressed as a product of holomorphic ...

      McOrist, Jock; Svanes, Eirik Eik (Peer reviewed; Journal article, 2022-11)
      It is believed, but not demonstrated, that the large radius massless spectrum of a heterotic string theory compactified to four-dimensional Minkowski space should obey equations that split into ‘F-terms’ and ‘D-terms’ in ...

      Boguslavski, K; Kurkela, Aleksi; Lappi, T; Peuron, J (Peer reviewed; Journal article, 2019-11)
      Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar ...

      Li, Qing; Geng, Jiahui; Evje, Steinar (Peer reviewed; Journal article, 2023-09)
      Machine learning methods have in various ways emerged as a useful tool for modeling the dynamics of physical systems in the context of partial differential equations (PDEs). Nonlinear conservation laws (NCLs) of the form ...

      Purpose Adjuvant endocrine treatment is essential for treating luminal subtypes of breast cancer, which constitute 75% of all breast malignancies. However, the detrimental side effects of treatment make it difficult for ...
    • Importance Sampling-based Transport Map Hamiltonian Monte Carlo for Bayesian Hierarchical Models 

      Osmundsen, Kjartan Kloster; Kleppe, Tore Selland; Liesenfeld, Roman (Peer reviewed; Journal article, 2021-06)
      We propose an importance sampling (IS)-based transport map Hamiltonian Monte Carlo procedure for performing a Bayesian analysis in nonlinear high-dimensional hierarchical models. Using IS techniques to construct a transport ...
    • Improved background subtraction and a fresh look at jet sub-structure in JEWEL 

      Milhano, José Guilherme; Zapp, Korinna Christine (Peer reviewed; Journal article, 2022)
      Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed ...
    • Improved Gauss law model and in-medium heavy quarkonium at finite density and velocity 

      Lafferty, David; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2020-03)
      We explore the in-medium properties of heavy-quarkonium states at finite baryochemical potential and finite transverse momentum based on a modern complex-valued potential model. Our starting point is a novel, rigorous ...
    • In-medium kinetic theory of D mesons and heavy-flavor transport coefficients 

      Torres-Rincon, Juan M.; Montaña, Glòria; Ramos, Àngels; Rigueiro, Laura Tolos (Peer reviewed; Journal article, 2022)
      We extend the kinetic theory of D mesons to accommodate thermal and off-shell effects due to the medium modification of the heavy-meson spectral functions. From the Kadanoff-Baym approach we derive the off-shell Fokker-Planck ...
    • Inhomogeneous chiral condensate in the quark-meson model 

      Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article, 2017)
      The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ...
    • Interpolation of weighted extremal functions 

      Rashkovskii, Alexander (Peer reviewed; Journal article, 2021-03)
      An approach to interpolation of compact subsets of Cn, including Brunn–Minkowski type inequalities for the capacities of the interpolating sets, was developed in [8] by means of plurisubharmonic geodesics between relative ...
