I will discuss a novel topological portal between quantum chromodynamics (QCD) and a dark QCD-like sector. Such a portal is present only for a unique coset structure after QCD confinement and it connects three QCD to two dark pions. When … Read More

Speakers: Jan Rozman Complex tissue flows in epithelia are driven by intra- and inter-cellular processes that generate, maintain, and coordinate mechanical forces. There has been growing evidence that cell shape anisotropy, manifested as nematic order, plays an important role in … Read More

Speakers: Somiealo Azote During embryonic development, the skin epidermis gradually transitions from a single layer of stem cells to a stratified, multi-layered tissue. This process involves the coordinated differentiation and upward movement of basal cells, known as delamination. It is … Read More

We revisit the decay rate of the electroweak vacuum in the Standard Model with the full one-loop prefactor. We focus on the gauge degrees of freedom and derive the degeneracy factors appearing in the functional determinant using group theoretical arguments. … Read More

Journal Club on WZW terms without anomalies: generalised symmetries in chiral Lagrangians (arXiv:2407.20340)Abstract:We consider a 4d non-linear sigma model on the coset $(text{SU}(N)_L times text{SU}(N)_R times text{SU}(2))/(text{SU}(N)_{L+R}times text{U})cong text{SU}(N) times S^2$, that features a topological Wess--Zumino--Witten (WZW) term whose curvature … Read More

Speakers: Nataša Adžič (Institute of Physics, Belgrade)  Studying static properties of colloidal suspensions is often a computationally expensive task due to their complex composition and interactions that appear at various length scales. Large macromolecules are surrounded by small solute particles … Read More
