Tensor renormalization group approach to the models via symmetry-twisted partition functions
Shinichiro Akiyama, Raghav G. Jha, Jun Maeda +2
We investigate critical phenomena in the models using symmetry-twisted partition functions that can be efficiently computed within the tensor renormalization group framework…
Tensor renormalization group approach to critical phenomena via symmetry-twisted partition functions
Shinichiro Akiyama, Raghav G. Jha, Jun Maeda +2
The locality of field theories strongly constrains the possible behaviors of symmetry-twisted partition functions, and thus they serve as order parameters to detect low-energy real…

Mingwei Dai, Walter Freeman, Jack Laiho +2
We study the behavior of the vacuum in Euclidean dynamical triangulations (EDT). Algorithmic improvements and better lattice spacing determinations allow us to test the properties…

We explore the potential application of quantum computers to the examination of lattice holography, which extends to the strongly-coupled bulk theory regime. With adiabatic evoluti…
Quantum Simulation of an Open System: A Dissipative 1+1D Ising Model
Erik Gustafson, Michael Hite, Jay Hubisz +2
The 1+1D Ising model is an ideal benchmark for quantum algorithms, as it is very well understood theoretically. This is true even when expanding the model to include complex coupli…

Mingwei Dai, Walter Freeman, Jack Laiho +2
We introduce a new algorithm for the simulation of Euclidean dynamical triangulations that mimics the Metropolis-Hastings algorithm, but where all proposed moves are accepted. This…

Erik J. Gustafson, Henry Lamm, Judah Unmuth-Yockey
We demonstrate the quantum mean estimation algorithm on Euclidean lattice field theories. This shows a quadratic advantage over Monte Carlo methods which persists even in presence…
