Collisions of false-vacuum bubble walls in a quantum spin chain
Ashley Milsted, Junyu Liu, John Preskill +1
We simulate, using nonperturbative methods, the real-time dynamics of small bubbles of "false vacuum" in a quantum spin chain near criticality, where the low-energy physics is desc…
On Quantum Simulation Of Cosmic Inflation
Junyu Liu, Yue-Zhou Li
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 algorith…
Quantum simulation with hybrid tensor networks
Xiao Yuan, Jinzhao Sun, Junyu Liu +2
Tensor network theory and quantum simulation are respectively the key classical and quantum computing methods in understanding quantum many-body physics. Here, we introduce the fra…
Scrambling and decoding the charged quantum information
Junyu Liu
Some deep conjectures about quantum gravity are closely related to the role of symmetries in the gravitational background, especially for quantum black holes. In this paper, we sys…
