Galerkin finite element approximation for semilinear stochastic time-tempered fractional wave equations with multiplicative white noise and fractional Gaussian noise

Then the space-time multiplicative white noise and fractional Gaussian noise are discretized, which results in a regularized stochastic fractional wave equation while introducing a modeling error in the mean-square sense. Expand abstract.

Space-time multilevel Monte Carlo methods and their application to cardiac electrophysiology

This combination allows for space-time adaptivity, time-changing domains, and to take advantage of past samples to initialize the space-time solution. Expand abstract.

Dark energy as a large scale quantum gravitational phenomenon

In our recently proposed quantum theory of gravity, the universe is made of `atoms' of space-time-matter (STM). Expand abstract.

Theoretical description and experimental simulation of quantum entanglement near open time-like curves via pseudo-density operators

Remarkably, our proposal applies to any space-time correlations violating entanglement monogamy, such as those arising in black holes. Expand abstract.

ESA Voyage 2050 white paper -- GrailQuest: hunting for Atoms of Space and Time hidden in the wrinkle of Space-Time

Although the predicted discrepancies are minuscule, Gamma-Ray Bursts, occurring at cosmological distances, could be used to detect this signature of space-time granularity with a new concept of modular observatory of huge overall collecting area consisting in a fleet of small satellites in low orbits, with sub-microsecond time...

Black hole shadow in the view of freely falling observers

For co-moving observers driven by cosmological constant in Schwarzschild-de Sitter space-time, we find that the angular radius of shadow could increase even when the observers move farther from the black hole. Expand abstract.

Global well-posedness of cubic fractional Schr\"odinger equations in one dimension

In this paper, we consider the Cauchy's problem of global existence and scattering behavior of small, smooth, and localized solutions of cubic fractional Schr\"odinger equations in one dimension, \begin{equation*} \mathrm{i} \partial_t u- (-\Delta)^{\frac{\alpha}{2}} u=c_* Expand abstract.
