Emergent Spacetime and Cosmic Inflation
UniverseWe present a novel background-independent framework for cosmic inflation, starting with a matrix model. In this framework, inflation is portrayed as a dynamic process responsible for the generation of both space and time.

Cosmic Strings from Thermal Inflation
UniverseThermal inflation was proposed as a mechanism to dilute the density of cosmological moduli. Thermal inflation is driven by a complex scalar field possessing a large vacuum expectation value and a very flat potential, called a “flaton”.

Quantum simulation of cosmic inflation [PDF]
Physical Review D, 2021 In this paper, we generalize Jordan-Lee-Preskill, an algorithm for simulating flat-space quantum field theories, to 3+1 dimensional inflationary spacetime. The generalized algorithm contains the encoding treatment, the initial state preparation, the inflation process, and the quantum measurement of cosmological observables at late time.

Physics Letters B, 2022 The standard cosmological model (ΛCDM) assumes that everything started in a singular Big Bang out of Cosmic Inflation, a mysterious form of modern Aether (the inflaton).

Running and Running of the Running of the Scalar Spectral Index in Warm Inflation
Universe, 2023 The next generation of cosmological observations are expected to improve the measurements of several quantities connected to the primordial inflation in the early Universe.

Cosmic Inflation and Genetic Algorithms
Fortschritte der Physik, 2022 AbstractLarge classes of standard single‐field slow‐roll inflationary models consistent with the required number of e‐folds, the current bounds on the spectral index of scalar perturbations, the tensor‐to‐scalar ratio, and the scale of inflation can be efficiently constructed using genetic algorithms.

Topics in Cosmology—Clearly Explained by Means of Simple Examples
Universe, 2022 This is a very comprehensible review of some key issues in modern cosmology. Simple mathematical examples and analogies are used, whenever available. The starting point is the well-known Big Bang cosmology (BBC).

Cosmic strings and inflation [PDF]
Nuclear Physics B, 1987 Abstract We examine the compatibility of inflation with the cosmic string theory for galaxy formation. There is a general conflict between having sufficient string tension to effect galaxy formation, and reheating after inflation to a high enough temperature that strings may form in a thermal phase transition.
