    Title: Manipulating the symmetry of charge order with light

    Abstract: New experimental tools can provide unexpected insights that can resolve `blind men and the elephant’ type issues that we often encounter in the study of complex materials. In this work we use a newly developed instrument that combines laser light with a scanning tunnelling microscope, to obtain crucial insights into the intriguing charge order observed in the Kagome compound RbV3Sb5.

    Title: Modulated instabilities and the AdS2 point in dense holographic matter

    Abstract: 

    We investigate the effect that a Chern-Simons term has on the phase diagram of quark matter at finite density and temperature. We carried out the complete fluctuation analysis of the chirally symmetric black hole phase of the holographic model V-QCD which models the deconfined phase of QCD. We classify all fluctuations and therefore all quasi-normal modes.

    Title: Non-invertible Symmetries in QED and QCD

    Abstract:

     I will discuss a novel kind of global symmetry, non-invertible symmetry, in QED and QCD. These symmetries are implemented by conserved operators that do not have an inverse, thus going outside the paradigm set by Wigner's theorem. The neutral pion decay in the real world can be interpreted as the consequence of this non-invertible symmetry.

    Title: Updates on the Atmospheric Properties of Pulsating Asymptotic Giant Branch Stars

    Abstract:

    Asymptotic Giant Branch (AGB) stars are a type of long-period variable star, marking the end-of-life stage for stars on the scale of the Sun. These stars experience opacity driven pulsations, driving the repeated contraction and expansion of the star. In the stellar atmosphere, the pulsations interact with mineral dusts, resulting in the mass-loss phenomenon, where material is shed from the star before becoming a white dwarf.
