Quantized Keys Steal Attention: Bias Correction for KV-Cache Compression in Video Diffusion
Tuna Tuncer, Felix Becker, Thomas Pfeil
Chunk-wise autoregressive video diffusion models rely on a KV cache of previously generated chunks to avoid redundant computation, but this cache quickly becomes a memory bottlenec…
Turning the knobs on dust evolution: Comparing codes, parameters and their effects on planet formation and disc observables
Linn E. J. Eriksson, Thomas Pfeil, Nicolas Kaufmann +1
Protoplanetary discs contain a wide range of dust sizes that influence their thermal structure and planet formation processes such as planetesimal formation and pebble accretion. D…
Planet formation at the inner edge of the dead zone -- I. the interplay between accretion outbursts and dust growth
Alexandros Ziampras, Tilman Birnstiel, Nicolas Kaufmann +2
The inner edge of the dead zone in protoplanetary disks has been shown to periodically go unstable, leading to accretion outbursts and annular substructure within the dead zone. Wh…
TriPoDPy: 1D Tri-Population size distributions forDust evolution in protoplanetary disks
Nicolas Leo Kaufmann, Thomas Pfeil, Sebastian Stammler +3
TriPoDPy is a code simulating the dust evolution, including dust growth and dynamics in protoplanetary disks using the parametric dust model presented in (Pfeil et al., 2024). The…
Dust Collisions in Protoplanetary Disks: Atomic Simulations of the Surface Free Energy
L. S. Morrissey, D. S. Ebel, L. E. J. Eriksson +4
Coagulation of dust particles in protoplanetary disks is the first step on the journey to the formation of planets. The surface free energy (SFE) of the dust particles determines t…
Fragmentation-limited dust filtration in 2D simulations of planet-disk systems with dust coagulation. Parameter study and implications for the inner disk's dust mass budget and composition
Thomas Pfeil, Philip J. Armitage, Yan-Fei Jiang
Super-thermal gas giant planets or their progenitor cores are known to open deep gaps in protoplanetary disks, which stop large, drifting dust particles on their way to the inner d…
