Nonlocal Nonstabilizerness from Holographic Schwinger Pair Production
Sebastian Grieninger
We analyze the emergence of nonlocal magic in Schwinger pair creation in strong non-Abelian (chromo)electric fields using holography. The produced quark--antiquark pair is entangle…
Nonequilibrium steady states in driven holographic Weyl semi-metals
Matteo Baggioli, Sebastian Grieninger, James Stokes
Three-dimensional Weyl materials provide a controlled setting for exploring Floquet dynamics in open quantum systems, including nonequilibrium steady states (NESS). Motivated by th…
Disordered Charged Horizons
Daniel Arean, Sebastian Grieninger, Pau G. Romeu
We construct fully backreacted charged black brane solutions with a spatially disordered chemical potential in asymptotically AdS and AdS, providing holographic duals of st…
Entanglement in massive Schwinger model at finite temperature and density
Sebastian Grieninger, Kazuki Ikeda, Dmitri E. Kharzeev +1
We evaluate the entanglement entropy and entropic function of massive two dimensional QED (Schwinger model) at finite temperature, density, and -angle. In the strong coupling re…
Temporal Entanglement Entropy as a probe of Renormalization Group Flow
Sebastian Grieninger, Kazuki Ikeda, Dmitri E. Kharzeev
The recently introduced concept of timelike entanglement entropy has sparked a lot of interest. Unlike the traditional spacelike entanglement entropy, timelike entanglement entropy…
Entanglement entropy in a time-dependent holographic Schwinger pair creation
Sebastian Grieninger, Dmitri E. Kharzeev, Ismail Zahed
We analyze the entanglement of a Schwinger pair created by a time-dependent pulse. In the semi-classical approximation, the pair creation by a pulse of external electric field is c…
Entanglement in a holographic Schwinger pair with confinement
Sebastian Grieninger, Dmitri E. Kharzeev, Ismail Zahed
We revisit the entanglement of a Schwinger pair created by external fields of arbitrary strength, using a holographic dual description of QCD. When external fields are strong in co…
Critical and near-critical relaxation of holographic superfluids
Mario Flory, Sebastian Grieninger, Sergio Morales-Tejera
We investigate the relaxation of holographic superfluids after quenches, when the end state is either tuned to be exactly at the critical point, or very close to it. By solving the…
Aspects of univalence in holographic axion models
Matteo Baggioli, Sebastian Grieninger, Sašo Grozdanov +1
Univalent functions are complex, analytic (holomorphic) and injective functions that have been widely discussed in complex analysis. It was recently proposed that the stringent con…
Pseudo-spontaneous Symmetry Breaking in Hydrodynamics and Holography
Martin Ammon, Daniel Arean, Matteo Baggioli +2
We investigate the low-energy dynamics of systems with pseudo-spontaneously broken symmetry and Goldstone phase relaxation. We construct a hydrodynamic framework which is ab…
A Holographic Superfluid Symphony
Daniel Arean, Matteo Baggioli, Sebastian Grieninger +1
We study the hydrodynamic excitations of backreacted holographic superfluids by computing the full set of quasinormal modes (QNMs) at finite momentum and matching them to the exist…
Second order equilibrium transport in strongly coupled supersymmetric Yang-Mills plasma via holography
Sebastian Grieninger, Ashish Shukla
A relativistic fluid in 3+1 dimensions with a global symmetry admits nine independent static susceptibilities at the second order in the hydrodynamic derivative expansion, w…
