The trilateral meetings are a series of one day events designed to strengthen the scientific relations in particle, astroparticle physics and cosmology between Trieste, Nova Gorica and Ljubljana. The 6th event will take place at the Jožef Stefan Institut in Ljubljana. The program: … Read More

We will be discussing the following paper: https://www.pnas.org/doi/full/10.1073/pnas.2208034119 ("Elastic properties and shape of the Piezo dome underlying its mechanosensory function"). The meeting will take place in the seminar room of physics (106).

We study the vertex model for epithelial tissue mechanics extended to include coupling between the cell shapes and tensions in cell-cell junctions. This coupling represents an active force which drives the system out of equilibrium and leads to the formation … Read More

We present an updated analysis of the first-order phase transition associated with symmetry breaking in the early Universe in a classically scale-invariant model extended with a new SU(2) gauge group. Including recent developments in understanding supercooled phase transitions, we compute … Read More

The meeting will take place in the seminar room of physics (room 106).

$V_{ub}$ is the smallest and least known of all CKM matrix elements; it's currently determined primarily through the exclusive process B → π l 𝜈. I will present progress toward a lattice QCD determination of the $V_{ub}$​ matrix element from a novel transition -- the B → π … Read More

Islets of Langerhans consist of a large functional syncytium of beta cells that produce pulses of insulin, a key component for controlling metabolic homeostasis. In response to stimulation, the islet cells display rather well-coordinated intercellular activity patterns, which was found … Read More

I will present a new approach to studying epithelial mechanics, which is based on representing the tissue structure by a graph. As a proof of concept, I will study a tissue with random cell rearrangements and compare the results with … Read More

A cosmological first-order phase transition would have given rise to a stochastic gravitational wave background which may be observable today. Phase transitions are driven by thermal loop fluctuations, which modify background fields at leading order. This breaks the usual loop … Read More
