The most powerful formula in physics starts with a slender S, the symbol for a sort of sum known as an integral. Further along comes a second S, representing a quantity known as action. Together, ...

Using the path-integral formalism, Ryan Parker, Mark Stedman and Luca Capriotti develop an accurate and easy-to-compute semi-analytical approximation for a general class of default intensity models.

This four-day mathematical physics conference takes place in Helsinki, September 3-6, 2024. It covers probabilistic and path integral methods in quantum and statistical field theory, highlighting in ...

Trapped bosons exhibit fundamental physical phenomena and are at the core of emerging quantum technologies. We present a method for simulating bosons using path integral molecular dynamics. The main ...

On Friday I took the train up to London to learn about “the theory that nobody wanted”. That’s how Cambridge University’s Michael Green described string theory in his introduction to a lecture of the ...

We consider the optimal estimation, prediction and control etc. of time series. The essence of a path integral characterization is considered to be that optimal estimates and decisions etc. are ...
