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…
Bootstrapping Heisenberg Magnets and their Cubic Instability
Shai M. Chester, Walter Landry, Junyu Liu +4
We study the critical model using the numerical conformal bootstrap. In particular, we use a recently developed cutting-surface algorithm to efficiently map out the allowed…
Quantum simulation of gauge theory via orbifold lattice
Alexander J. Buser, Hrant Gharibyan, Masanori Hanada +2
We propose a new framework for simulating Yang-Mills theory on a universal quantum computer. This construction uses the orbifold lattice formulation proposed by Kapla…
Toward simulating Superstring/M-theory on a quantum computer
Hrant Gharibyan, Masanori Hanada, Masazumi Honda +1
We present a novel framework for simulating matrix models on a quantum computer. Supersymmetric matrix models have natural applications to superstring/M-theory and gravitational ph…
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…
The Lorentzian inversion formula and the spectrum of the 3d O(2) CFT
Junyu Liu, David Meltzer, David Poland +1
We study the spectrum and OPE coefficients of the three-dimensional critical O(2) model, using four-point functions of the leading scalars with charges 0, 1, and 2 (, , and $…
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…
Quantum simulation of quantum field theories as quantum chemistry
Junyu Liu, Yuan Xin
Conformal truncation is a powerful numerical method for solving generic strongly-coupled quantum field theories based on purely field-theoretic technics without introducing lattice…
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…
