Open AccessTime evolution of Einstein-Maxwell-scalar black holes after a thermal quench
We employ the holographic quench technique to drive Einstein-Maxwell-scalar (EMs) black holes out of equilibrium and study the real-time dynamics therein. From the fully nonlinear dynamical simulations, a dyna...

Open AccessBaby skyrmion in two-component holographic superfluids
In the two-component Ginzburg-Landau theory of superfluidity, a pair of fractional vortices form a composite type of topological defect, usually referred to as a baby skyrmion. In this paper, we initiate the c...

Open AccessSL(2, R) × U(1) symmetry and quasinormal modes in the self-dual warped AdS black hole
The algebraic approach to the spectrum of quasinormal modes has been made as simple as possible for the BTZ black hole by the strategy developed in [16]. By working with the self-dual warped AdS black hole, we...

Open AccessSplitting of doubly quantized vortices in holographic superfluid of finite temperature
The temperature effect on the linear instability and the splitting process of a doubly quantized vortex is studied. Using the linear perturbation theory to calculate out the quasi-normal modes of the doubly qu...

Open AccessCritical dynamics in holographic first-order phase transition
We study the critical phenomena of the dynamical transition from a metastable state to a stable state in the model of first-order phase transition via two different triggering mechanisms. Three universal stage...

Open AccessHolographic Einstein ring of a charged AdS black hole
Taking into account that the real quantum materials are engineered generically at a finite chemical potential, we investigate the Einstein ring structure for the lensed response of the complex scalar field as ...

Open AccessNonequilibrium dynamical transition process between excited states of holographic superconductors
We study the dynamics of the holographic s-wave superconductors described by the Einstein-Maxwell-complex scalar field theory with a negative cosmological constant. If the eigenfunction of the linearized equation...

Open AccessShadows and photon spheres with spherical accretions in the four-dimensional Gauss–Bonnet black hole
We investigate the shadows and photon spheres of the four-dimensional Gauss–Bonnet black hole with the static and infalling spherical accretions. We show that, for both cases, there always exist shadows and ph...

Open AccessGeneration of vortices and stabilization of vortex lattices in holographic superfluids
Within the simplest holographic superfluid model and without any ingredient put by hand, it is shown that vortices can be generated when the angular velocity of rotating superfluids exceeds certain critical va...

Open AccessStrong cosmic censorship for the Dirac field in the higher dimensional Reissner-Nordstrom-de Sitter black hole
We investigate the strong cosmic censorship for the Dirac field in the higher dimensional Reissner-Norstrom-de Sitter black hole. To achieve this, we first use the con- formal transformation trick to massage t...

Open AccessBlack and gray solitons in holographic superfluids at zero temperature
We construct gray soliton configurations, which move at constant speeds, in holographic superfluids for the first time. Since there should be no dissipation for a moving soliton to exist, we use the simplest h...

Open AccessStrong Cosmic Censorship in higher-dimensional Reissner-Nordström-de Sitter spacetime
: It was recently shown that Strong Cosmic Censorship might be violated for near-extremally-charged black holes in 4-dimensional de Sitter space under scalar perturbations. Here, we extend the study of neutral...

Open AccessStrong cosmic censorship for the massless Dirac field in the Reissner-Nordstrom-de Sitter spacetime
We present the Fermi story of strong cosmic censorship in the near-extremal Reissner-Nordstrom-de Sitter black hole. To this end, we first derive from scratch the criterion for the quasi-normal modes of Dirac ...

Open AccessTowards quantum turbulence in finite temperature Bose-Einstein condensates
Motivated by the various indications that holographic superfluid is BCS like at the standard quantization but BEC like at the alternative quantization, we have implemented the alternative quantization in the d...

Open AccessDynamical stability of the holographic system with two competing orders
We investigate the dynamical stability of the holographic system with two order parameters, which exhibits competition and coexistence of condensations. In the linear regime, we have developed the gauge depend...

Open AccessHolographic thermal relaxation in superfluid turbulence
Holographic duality provides a first-principles approach to investigate real time processes in quantum many-body systems, in particular at finite temperature and far-from-equilibrium. We use this approach to s...

Does target animacy influence manual laterality of monkeys? First answer from northern pig-tailed macaques (Macaca leonina)
The evolutionary origin of human right-handedness remains unclear. Many factors such as emotion and tool use have been implicated in primate handedness evolution. With regard to emotional lateralization, most ...

Open AccessHolographic quenches and fermionic spectral functions
Using holographic methods we investigate the behaviour of fermionic spectral functions of strongly coupled 2 + 1 dimensional field theories as both temperature and chemical potential are quenched.

Open AccessHolographic entropy production
The suspicion that gravity is holographic has been supported mainly by a variety of specific examples from string theory. In this paper, we propose that such a holography can actually be observed in the contex...
