Quantum tachyonic preheating, revisited
In certain models of inflation, the postinflationary reheating of the Universe is not primarily due to perturbative decay of the inflaton field into particles, but proceeds through a tachyonic instability.

Four results on out-of-equilibrium 2PI simulations in 3+1 dimensions
We perform an analysis of a number of approximations and methods used in numerical simulations of real-time Kadanoff-Baym equations based on truncations of the 2PI effective action.

Quantum simulation with gauge fixing: From Ising lattice gauge theory to dynamical flux model
Quantum simulation of synthetic dynamic gauge field has attracted much attentions in recent years. There are two traditional ways to simulate gauge theories.

Quantum decoherence in the Caldeira-Leggett model by the real-time path integral on a computer
We propose first-principle calculations of an open system based on the real-time path integral formalism treating the environment as well as the system of our interest together on a computer.

Exotic phases in finite-density ℤ 3 theories
Lattice ℤ 3 theories with complex actions share many key features with finite- density QCD including a sign problem and CK $$ \mathcal{CK} $$ symmetry.
