3. From Killing Twins to Simulating Mergers: Probing Dense QCD with Neutron Stars and Numerical Relativity

Christian Ecker

09/09/2026 11:00

Neutron stars provide a unique laboratory for dense QCD, but extracting information about their microscopic composition requires both robust constraints on the equation of state (EOS) and accurate simulations of their dynamics. I will discuss recent progress along these complementary directions. First, I will show how model-agnostic EOS inference, constrained by chiral effective field theory,...

6. Effective and holographic description of fluctuations in first order phase transitions

Carlos Hoyos Badajos

When fluctuations are suppressed in first order phase transitions, bubble nucleation may be too slow to complete the transition, and the system may explore configurations beyond stable and metastable states. The system can exhibit qualitative differences in thermodynamic and dynamic properties depending on the strength of the coupling, or more precisely, on the number of degrees of freedom...

1. Self-sustained, out-of-equilibrium inflation

Jorge Casalderrey Solana

10/09/2026 09:00

We use holography to study dS-invariant states of non-conformal, strongly coupled quantum field theories in four-dimensional de Sitter space. We show that out-of-equilibrium effects can sustain exponential inflation within the regime of validity of semiclassical gravity, $H \ll M \ll M_{\text{sp}}$, where $H$ is the Hubble parameter, $M$ is the QFT characteristic scale, $M_{\text{sp}} = M_p /...

12. Non-conformal obstructions to bubble expansion

Mikel Sanchez Garitaonandia

10/09/2026 11:00

The hydrodynamics of expanding bubbles plays an important role in the study of gravitational wave emission from first-order phase transitions. It determines the possible expansion types and provides an estimate of the energy available for gravitational wave emission. By interpolating between electroweak- and QCD-like transitions, I will investigate the hydrodynamics of expanding bubbles in...

15. From pQCD to neutron-star cores: recent advances in equation-of-state inference

Aleksi Vuorinen

10/09/2026 14:50

I will discuss recent developments in high-order
perturbative QCD calculations at high baryon density. These efforts have
now reached the full next-to-next-to-next-to-leading order (N3LO) for
the pressure of cold and dense QED matter and are approaching the same
order for cold quark matter. The latter result is expected to
substantially improve theoretical control over the high-density...

13. Nuclear chiral density wave from field theory and holography

Andreas Schmitt

11/09/2026 09:00

Cold and dense QCD matter may break rotational invariance spontaneously. One anisotropic candidate phase is the chiral density wave, where the chiral condensate oscillates between scalar and pseudoscalar sectors. I will present results from a nucleon-meson model that allows for a chiral phase transition. Taking into account the conditions in the interior of neutron stars and constraints from...

4. Learning quark-gluon plasma properties holographically with neural ODEs

Song He

11/09/2026 11:00

We use neural ODEs and state-of-the-art lattice QCD thermodynamics to calibrate a holographic Einstein-Maxwell-Dilaton model with Gauss-Bonnet corrections. The model quantitatively reproduces the equation of state at zero and finite baryon chemical potential and predicts the phase structure in the T-\mu_B plane, a temperature-dependent, and a peaked, while remaining consistent with...
