Taylor expansions on Lefschetz thimbles (and not only that)
Francesco Di Renzo, Simran Singh, Kevin Zambello
Thimble regularisation is a possible solution to the sign problem, which is evaded by formulating quantum field theories on manifolds where the imaginary part of the action stays c…

One-thimble regularisation of lattice field theories: is it only a dream?
Francesco Di Renzo, Simran Singh, Kevin Zambello
Lefschetz thimbles regularisation of (lattice) field theories was put forward as a possible solution to the sign problem. Despite elegant and conceptually simple, it has many subtl…
