Seminars

Title: Collective vortex dynamics in strongly coupled superfluids Speaker: Mikel Sanchez-Garitaonandia (University College Dublin) Venue&Time: Red Room / 15:00 Abstract: Vorticity appears across a wide range of fluid phenomena, from the dynamics of classical fluids to quantum vortices in superfluids. In the latter case, vortices are topological defects that interact both with each other and […]

Title: Quantum computing for lattice gauge theories: from the Schwinger model to an SO(3) Quantum Link model Speaker: Bipasha Chakraborty (University of Southampton) Venue&Time: Red Room / 15:00 Abstract: Quantum computing provides a promising framework for simulating strongly coupled gauge theories relevant to high-energy physics. In this talk, I will discuss quantum simulations of lattice […]

Title: Gravitational waves from phase transitions in the early Universe: sound waves and MHD turbulence Speaker: Alberto Roper Pol (Geneva) Venue&Time: Red Room / 15:00 Abstract:  Gravitational waves (GWs) can be produced by a first-order phase transition in the early Universe via the fluid perturbations induced in the primordial plasma by the expansion and collision […]

Title: 'Are string vacua connected?' Speaker: Ashoke Sen (ICTS-Infosys) Venue&Time: 11:00 / Blue Room Abstract: String theory has many vacua. We shall examine the question of whether these vacua are connected from an experimentalist's perspective. Ashoke Sen is the ICTS-Infosys Madhava Chair Professor at the International Centre for Theoretical Sciences, Bengaluru. His major honours include […]

Title: Entanglement through topological interfaces in CFT revisited Speaker: Christian Northe (Institute of Physics, Prague) Venue&Time: Red Room / 15:00 Abstract: Present theoretical predictions for the entanglement entropy through topological defects are violated in numerical simulations of critical systems. In this talk, I discuss a paradigm shift in the preparation of reduced density matrices in […]

Title: 'Primordial Black Holes -- Positivist Perspective, Quantum Quiddity and Galaxy Genesis' Speaker: Florian Kühnel, (TU Dortmund & LMU Munich) Venue&Time: Red Room / 15:00 Abstract: Primordial black holes are black holes that may have formed in the early Universe. Their masses potentially span a range from as low as the Planck mass up to […]

Title: 'Perturbative aspect of electroweak phase transitions in the Early Universe' Speaker: Andrii Dashko (DESY) Venue&Time: Blue Room / 12:00 Abstract: We present a study of the perturbative description of thermally driven electroweak phase transitions (EWPT) in the early universe. Focusing on strong first-order transitions, which are relevant for gravitational wave cosmology, we examine the […]

Title: 'On the evidence for elastic interactions in the dark sector' Speaker: Jose Beltrán Jiménez, University of Salamanca. Venue & Time: Red Room / 15:00 Abstract: The increasing quality of cosmological data has revealed > some tensions among different probes that could be signalling the necessity of incorporating new physics into our cosmological model. One […]

Title: Exploring Effective Theories of Gauged Chiral Symmetries at the LHC and Beyond Speaker: Felix Yu (Mainz U.) Venue & Time: Red Room / 15:00 Abstract: I discuss theoretical issues with constructing effective theories of gauged chiral symmetries, taking a quark-universal U(1)_B symmetry as an example.  I will review the phenomenology of the Z-Z’-photon vertex and point […]

Title: 'Weak Particles with a strong impact' Speaker: Aritra Gupta (Krea University, India) Venue&Time: Red Room / 15:00 Abstract: Dark matter and neutrinos are among the most elusive particles in nature, yet they play a central role in the evolution of the Universe. Their extremely weak interactions make them difficult to detect, but also allow […]
