Dynamic Modulated Arc Therapy (DMAT): A Time Aware, Modulation Steered Optimization Framework for Next Generation Radiotherapy Delivery
Taoran Li, Esa Kuusela, Emmi Ruokokoski +10
Background: Conventional VMAT optimization treats delivery time and deliverability as emergent properties of control-point-centric models that ignore finite acceleration and other…
Tying Quantum Knots
David S. Hall, Michael W. Ray, Konstantin Tiurev +3
Knots are familiar entities that appear at a captivating nexus of art, technology, mathematics, and science. As topologically stable objects within field theories, they have been s…
Decay of an isolated monopole into a Dirac monopole configuration
K. Tiurev, E. Ruokokoski, H. Mäkelä +2
We study numerically the detailed structure and decay dynamics of isolated monopoles in conditions similar to those of their recent experimental discovery. We find that the core of…
Creation and dynamics of two-dimensional skyrmions in antiferromagnetic spin-1 Bose-Einstein condensates
T. Ollikainen, E. Ruokokoski, M. Möttönen
We numerically simulate the creation process of two-dimensional skyrmionic excitations in antiferromagnetic spin-1 Bose--Einstein condensates by solving the full three-dimensional…
Stationary States of Trapped Spin-Orbit-Coupled Bose-Einstein Condensates
Emmi Ruokokoski, Jukka A. M. Huhtamäki, Mikko Möttönen
We numerically investigate low-energy stationary states of pseudospin-1 Bose-Einstein condensates in the presence of Rashba-Dresselhaus-type spin-orbit coupling. We show that for e…
Ground-State Dirac Monopole
Emmi Ruokokoski, Ville Pietilä, Mikko Möttönen
We show theoretically that a monopole defect, analogous to the Dirac magnetic monopole, may exist as the ground state of a dilute spin-1 Bose-Einstein condensate. The ground-state…
