90. Why I'm excited about working in Computing Division in 10 minutes

Marianette Wospakrik (Fermilab)

High Energy Physics is entering an exciting period with new insights into many of the fundamental mysteries of the universe, especially with developments in "big data" analyses. Continuous exploration of new, cutting-edge technologies and techniques is required to unravel these mysteries for scientific discovery. One of these mysteries lies also in neutrino physics and known as the...

39. OASIS: Optimal Analysis-Specific Importance Sampling for event generation

We provide a technique called OASIS to reduce the number of simulated events required in a collider analysis to reach a target sensitivity. We achieve this by preferentially focusing the event generation in different regions of phase-space based on their utility to the analysis at hand (and appropriately weighting the events).

OASIS leads to a conservation of resources at all stages of...

85. Simulating high-energy physics on a quantum computer

Quantum field theory (QFT) provides a framework to study phenomena in high-energy physics. However, its simulation in the strong interaction regime remains computationally challenging. Quantum computing could serve as an efficient tool to simulate QFT models in the future. In this talk, I will discuss a quantum algorithm to simulate the phi4 scalar model.

Tricritical Ising model (TIM) is a simple quantum spin chain model with a tricritical point separating a Ising phase transition line from a first-order transition line. We perform quantum simulation of the dynamical phase transition in TIM with Friedmann-Robertson-Walker metric. The results in principle could help us to understand the non-equilibrium dynamics in the early universe.
