Bound of diffusion constants from pole-skipping points: spontaneous symmetry breaking and magnetic field

Journal of High Energy Physics, 2021
We investigate the properties of pole-skipping of the sound channel in which the translational symmetry is broken explicitly or spontaneously. For this purpose, we analyze, in detail, not only the holographic axion model, but also the magnetically ...

Holographic entanglement density for spontaneous symmetry breaking

Journal of High Energy Physics, 2022
We investigate the properties of the holographic entanglement entropy of the systems in which the U(1) or the translational symmetry is broken spontaneously.

Observation of Weyl fermions in a magnetic non-centrosymmetric crystal

Nature Communications, 2020
The search for magnetic Weyl fermion remains a challenge. Here, the authors report angle-resolved photoemission spectroscopy and magnetotransport measurements resolving the topological properties of Weyl fermion quasiparticles in magnetic non ...

Quasi-normal modes of dyonic black holes and magneto-hydrodynamics

Journal of High Energy Physics, 2022
We revisit the magneto-hydrodynamics in (2+1) dimensions and confirm that it is consistent with the quasi-normal modes of the (3+1) dimensional dyonic black holes in the most general set-up with finite density, magnetic field and wave vector.

The breakdown of magneto-hydrodynamics near AdS2 fixed point and energy diffusion bound

Journal of High Energy Physics, 2022
We investigate the breakdown of magneto-hydrodynamics at low temperature (T) with black holes whose extremal geometry is AdS2×R2. The breakdown is identified by the equilibration scales (ω eq , k eq) defined as the collision point between the diffusive ...

Spin-orbit quantum impurity in a topological magnet

Nature Communications, 2020
Single-atomic impurities may induce novel quantum state, but they are unexplored in topological magnets. Here, the authors report spin-down polarized bound states which further interact with neighboring states to form spin-orbit split quantized orbitals ...

Upper bound of the charge diffusion constant in holography

Journal of High Energy Physics, 2022
We investigate the upper bound of charge diffusion constant in holography. For this purpose, we apply the conjectured upper bound proposal related to the equilibration scales (ω eq, k eq) to the Einstein-Maxwell-Axion model.

Bose glass and Fermi glass

Scientific Reports, 2023
It is known that two-dimensional superconducting materials undergo a quantum phase transition from a localized state to superconductivity. When the disordered samples are cooled, bosons (Cooper pairs) are generated from Fermi glass and reach ...

A molecular descriptor of intramolecular noncovalent interaction for regulating optoelectronic properties of organic semiconductors

Nature Communications, 2023
In recent years, intramolecular noncovalent interaction has become an important means to modulate the optoelectronic performances of organic/polymeric semiconductors. However, it lacks a deep understanding and a direct quantitative relationship among the
