Then, we introduce a few useful and practical applications of the algorithm.

    Prof. Deog Ki Hong (Pusan National University)
    22/02/2023, 15:40

    We show that dark matter axions or axion-like particles (ALP) induce spontaneously alternat- ing electric currents in conductors along the external magnetic fields due to the (medium) axial anomaly, realizing the chiral magnetic effects. We propose a new experiment to measure this cur- rent to detect the dark matter axions or ALP. These induced currents are the electron medium effects,...

  31. 44. Gravitational Lensing in Gravitational Waves - Virtual
    Dr Kyungmin Kim (Ewha Womans University)
    23/02/2023, 16:10

    Like electromagnetic waves propagating in the universe, gravitational waves (GWs) can be gravitationally lensed by massive objects between the distant source and the observer. Consequently, considering all known types of lensing configurations—governed by not only the relative position of the source to the lens but the size, shape, and distribution of the lens mass—is possible for the...

  33. 47. Primordial Cosmic complexity and effect of reheating
    Dr Pankaj Saha (Seoultech)
    23/02/2023, 17:10

    We study the effect of reheating phase on the evolution of complexities in the primordial scalar fluctuations using the squeezed formalism. We study the evolution of the out-of-time correlator (OTOC) and the quantum discord starting from the inflationary epoch till the radiation-dominated epoch with different types of reheating phases. We find that, for a mode that re-enters the horizon after...

  38. 51. Halo-independent bounds on the non-relativistic effective theory of WIMP-nucleon scattering from direct detection and neutrino observations
    Dr Arpan Kar (Sogang University)
    24/02/2023, 11:40

    In my presentation I will talk about the halo-independent bounds on the WIMP-nucleon couplings of the non-relativistic effective Hamiltonian that drives the scattering process off nuclei of a WIMP of spin 1/2. We will see that for most of the couplings the degree of relaxation of the halo-independent bounds compared to those obtained by assuming the Standard Halo Model is with few exceptions...
