Particle creation in cosmological space–time by a time-varying electric field
AbstractWe use the semiclassical approach to solve the Klein–Gordon and Dirac equations in the presence of a time-varying electric field. Our...

Space-time generalization of mutual information
The mutual information characterizes correlations between spatially separated regions of a system. Yet, in experiments we often measure dynamical...

Testing space-time non-commutativity with TianQin
The direct detection of gravitational waves offers a powerful tool to explore the nature of gravity and the structure of space-time. This paper...

Symmetries of κ-Minkowski space-time: a possibility of exotic momentum space geometry?
The quest for a quantum gravity phenomenology has inspired a quantum notion of space-time, which motivates us to study the fate of the relativistic...

Asymmetric space–time correlated continuous-time random walk
AbstractIn this manuscript, we present an asymmetric space–time correlated continuous-time random walk model. The waiting time distribution is...

Space-Time Fluctuations in a Quasi-static Limit
We consider the macroscopic limit for the space-time density fluctuations in the open symmetric simple exclusion in the quasi-static scaling limit....

Time-Efficient Constant-Space-Overhead Fault-Tolerant Quantum Computation
Scaling up quantum computers to attain substantial speedups over classical computing requires fault tolerance. Conventionally, protocols for...

Consistent travelling wave characteristic of space–time fractional modified Benjamin–Bona–Mahony and the space–time fractional Duffing models
Study on solitary wave phenomenon are closely related on the dynamics of the plasma and optical fiber system, which carry on broad range of wave...

Space–Time–Matter
This work aims to shed some light on the meaning of the positive energy assumption in relativistic quantum theory and its relation to questions of...

Space Time Method for Solving KdV and KdV-Burgers’ Equation
AbstractKorteweg-de Vries equation and KdV-Burgers’ equation are important nonlinear evolutionary equations widely used in engineering and...

Gauge theory on ρ-Minkowski space-time
We construct a gauge theory model on the 4-dimensional ρ -Minkowski space-time, a particular deformation of the Minkowski space-time recently...

The Art of Gluing Space-Time Manifolds Methods and Applications
This concise book reviews methods used for gluing space-time manifolds together. It is therefore relevant to theorists working on branes, walls,...

Multi-state quantum simulations via model-space quantum imaginary time evolution
We introduce the framework of model space into quantum imaginary time evolution (QITE) to enable stable estimation of ground and excited states using...

Finslerian analogue of the Schwarzschild–de Sitter space-time
This paper aims to study the Finslerian equivalent of Schwarzschild–de Sitter space-time. We propose the gravitational field equation with a...

Non-spherical sources of Schwarzschild space-time
While it is known that any spherical fluid distribution may only source the spherically symmetric Schwarzschild space-time, the inverse is not true....

Broadband control of topological–spectral correlations in space–time beams
The synthesis of ultrashort pulses with simultaneously tailored spatial and temporal properties opens new horizons in multimode photonics, especially...

Relational Space-Time and de Broglie Waves
Relative motion of particles is examined in the context of relational space-time. It is shown that de Broglie waves may be derived as a...

Particle realization of Bondi-Metzner-Sachs symmetry in 2 + 1 space-time
We construct a Lorentz invariant massive particle model in (2+1) space-time with an enlarged set of symmetries which includes Bondi-Metzner-Sachs...

Emergent metric space-time from matrix theory
The IKKT matrix model yields an emergent space-time. We further develop these ideas and give a proposal for an emergent metric. Based on previous...
