Nudžeim Selimović: Topological Portal to the Dark Sector
Nudžeim Selimović: Topological Portal to the Dark Sector
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

Jan Rozman, “From Substrate Dissipation to Internal Dissipation Vertex Model Dynamics: Generating Sustained Flows”
Jan Rozman, “From Substrate Dissipation to Internal Dissipation Vertex Model Dynamics: Generating Sustained Flows”
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

Somiealo Azote, “Quantitative Predictions of biomechanical drivers of cell delamination in stratified epithelia (skin epidermis) using a dynamic 3D vertex model”
Somiealo Azote, “Quantitative Predictions of biomechanical drivers of cell delamination in stratified epithelia (skin epidermis) using a dynamic 3D vertex model”
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

Shoji, Baratella: The Standard Model lifetime is slightly shorter
Shoji, Baratella: The Standard Model lifetime is slightly shorter
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

Pietro Baratella: Journal Club on WZW terms without anomalies: generalised symmetries in chiral Lagrangians
Pietro Baratella: Journal Club on WZW terms without anomalies: generalised symmetries in chiral Lagrangians
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
Nataša Adžić, “The role of effective interactions in predicting the exotic states of soft matter”
Nataša Adžić, “The role of effective interactions in predicting the exotic states of soft matter”
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
