We have just published two @PhysRevLett papers in 14 days 💪 Both about the dissipative effects in fermionic superfluids. First in fermionic Josephson-Junction (link.aps.org/doi/10.1103/Phy…). Second of fermionic quantum vortices (link.aps.org/doi/10.1103/Phy…) 🌪️

Paper Alert! 🚨 The analysis of the structure of fermionic vortices with the spin-polarized core in two coupling limits is presented. We show and explain the reversed circulation in the vortex core induced by an excess of majority spin particles. Phys. Rev A 106, 033322📒

#postdoc alert 🚨 Our work is focused on a theoretical description of low energy #nuclear reactions. We are highly interested in the role of pairing dynamics in superheavy elements synthesis. Our framework is TDDFT utilized on a #HPC systems. More info in DM
We got it! @NCN_PL #Opus22 grant for: Low-energy collisions involving heavy nuclei in the time-dependent density functional theory. We will make a contribution to super heavy elements synthesis.
Our former master student is an author of this beautiful work! 🌀🌪️Congratulations! 🎉

Published!! ..Finally!!✨🥳 In the article we analyze generation/decay dynamics of tangled quantum vortices in a cylinder in spin-(un)polarized unitary Fermi gases. Presence of two distinct decay regimes is discussed. Phys. Rev. A 105, 013304 (2022) journals.aps.org/pra/abstrac…

Ever try twisting a spinning bike tire? It's hard! The same is true of a spinning nucleus. If it has to change the orientation of its spin, it takes a lot longer to decay. We call this a "K isomer" (for math reasons).

I have delivered three online lectures at #IUAC School on #Nuclear #Reactions 2021, entitled "Time-Dependent Hartree-Fock Theory and Its Extensions for Low-Energy Heavy-Ion Reactions". About the school: gate.iuac.res.in/NRSCHOOL/ Lecture slides are available at: (see threads↓)

New preprint!!✨We report novel effects of superfluidity in nuclear reactions. One of those is a collision-induced dynamical symmetry breaking, leading to Higgs mode excitations. I believe the attached figure already tells you a lot. For details, see: arxiv.org/abs/2111.05135

in particular, to determine the interactions between nuclei and its role in deforming the lattice and creating the nuclear pasta phase. We will use the state-of-the-art modern models that describe interiors of neutron stars [2/3]

and petaflops supercomputers which make 2.5 x 10^18 operations every second. With such help, we will create three-dimensional simulations showing the dynamics of nuclei immersed in neutron matter. From that, we will deduce the interaction between the nuclear clusters.
I gave an online lecture series (3 lectures), titled "Nuclear Dynamics from Time-Dependent Density Functional Theory: From Nuclear Reactions, Superfluid Phenomena, to Neutron Stars", at the YONUPA Summer School 2021. Lecture slides are available at: (see reply)
