Perturbative Removal of a Sign Problem
Scott Lawrence
This paper presents a method for alleviating sign problems in lattice path integrals, including those associated with finite fermion density in relativistic systems. The method mak…
Sign Problems in Quantum Field Theory: Classical and Quantum Approaches
Scott Lawrence
Monte Carlo calculations in the framework of lattice field theory provide non-perturbative access to the equilibrium physics of quantum fields. When applied to certain fermionic sy…
The thermodynamics of large-N QCD and the nature of metastable phases
Thomas D. Cohen, Scott Lawrence, Yukari Yamauchi
In the limit of a large number of colors (N), both Yang-Mills and quantum chromodynamics are expected to have a first-order phase transition separating a confined hadronic phase an…
Suppressing Coherent Gauge Drift in Quantum Simulations
Henry Lamm, Scott Lawrence, Yukari Yamauchi
Simulations of field theories on noisy quantum computers must contend with errors introduced by that noise. For gauge theories, a large class of errors violate gauge symmetry, and…
The Brute-Force Search for Planet Nine
Scott Lawrence, Zeeve Rogoszinski
A recent proposal for the detection of a hypothetical gravitating body 500 AU from the Sun (termed Planet 9) calls for a fleet of near-relativistic spacecraft, equipped with high-p…
Quantum Simulation of Field Theories Without State Preparation
Siddhartha Harmalkar, Henry Lamm, Scott Lawrence
We propose an algorithm for computing real-time observables using a quantum processor while avoiding the need to prepare the full quantum state. This reduction in quantum resources…
