    Andersen, Jens Oluf; Tranberg, Anders; Eriksson, Magdalena Britt (Peer reviewed; Journal article, 2022-02)
    The non-linear dynamics of long-wavelength cosmological fluctuations may be phrased in terms of an effective classical, but stochastic evolution equation. The stochastic noise represents short-wavelength modes that continually ...
  • Quarkonium production and suppression: Theory 

    Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2021-01)

  • DD¯ ∗ scattering and χc1(3872) in nuclear matter 

    Albaladejo, M.; Nieves, J.; Tolos Rigueiro, Laura (Peer reviewed; Journal article, 2021-09)
    We study the behavior of the χc1(3872), also known as X(3872), in dense nuclear matter. We begin from a picture in vacuum of the X(3872) as a purely molecular (DD¯¯¯∗-c.c) state, generated as a bound state from a heavy-quark ...

    Since 2015 the gravitational-wave observations of LIGO and Virgo have transformed our understanding of compact-object binaries. In the years to come, ground-based gravitational-wave observatories such as LIGO, Virgo, and ...

    We demonstrate that oxygen-oxygen collisions at the LHC provide unprecedented sensitivity to parton energy loss in a system whose size is comparable to those created in very peripheral heavy-ion collisions. With leading ...
  • Soft Interactions in Cold Quark Matter 

    Gorda, Tyler; Kurkela, Eero Aleksi; Paatelainen, Risto; Säppi, Saga; Vuorinen, Aleksi (Peer reviewed; Journal article, 2021-10)
    Accurate knowledge of the thermodynamic properties of zero-temperature, high-density quark matter plays an integral role in attempts to constrain the behavior of the dense QCD matter found inside neutron-star cores, ...
  • Transport Properties of Superfluid Phonons in Neutron Stars 

    Manuel, Cristina; Tolos Rigueiro, Laura (Peer reviewed; Journal article, 2021-03)

  • Interpolation of weighted extremal functions 

    Rashkovskii, Alexander (Peer reviewed; Journal article, 2021-03)
