A . Roldan-Molina, A.S. Nunez, and R.A. Duine, Magnonic black holes, Phys. Rev. Lett. 118, 061301 (2017); this work is the first to give a concrete proposal for implementing event horizons for spin waves. It was mentioned as a research highlight in Nature Physics 13, 1 (2017).

B. Flebus, S. A. Bender, Y. Tserkovnyak, and R. A. Duine, Two-Fluid Theory for Spin Superfluidity in Magnetic Insulators, Phys. Rev. Lett. 116, 117201 (2016); this paper provides a unified theoretical description of coherent (superfluid) and incoherent (thermal) spin transport carried by magnons that is rooted in a microscopic theory.
L.J. Cornelissen, J. Liu, R.A. Duine, J. Ben Youssef, B.J. Van Wees, Long distance transport of magnon spin information in a magnetic insulator at room temperature, Nature Physics 11, 1022 (2015); This paper is the first to demonstrate spin currents through a magnetic insulator. My group contributed by developing its theoretical description that unifies magnon and electron spin transport. I expect this paper to be among the defining publications of “magnon spintronics”, the field which holds the prospect of achieving room-temperature transfer of information without dissipation. See here for the FOM press release. Here you can find a short radio item of BNR about this work, and here you can find a short piece in the Digitaal U-Blad.

Rosch, Spin Transfer Torques in MnSi at Ultra-low Current Densities, Science 330, 1648 (2010); this paper is the first to demonstrate spin-transfer torques in chiral magnets, in particular in the skyrmion lattice phase. The critical currents are several order of magnitude lower than what was previously achieved, and the finding of this paper led to the field of "skyrmionics", spintronics with skyrmions.

J.W. Reijnders and R.A. Duine, Pinning of vortices in a Bose-Einstein condensate by an optical lattice, Phys. Rev. Lett. 93, 060401 (2004); this article is the first to propose vortex pinning in atomic Bose-Einstein condensates. This is my first publication that does not involve my Ph. D. supervisor, and its theoretical predictions were experimentally confirmed a few years later in the group of Nobel laureate Eric Cornell [Phys. Rev. Lett. 97, 240402 (2006)].
