Path Resummations and the Fermion Sign Problem
... Carlo (QMC) simulations of Fermion systems based on the idea of sampling “graphs”, rather than “paths”. The latter, being rooted in Feynman’s “realspace imaginary-time” path-integral (PI) theory [2–4], has been the paradigmatic approach to simulating quantum systems at finite temperature. For Fermion ...

A History of Physics as an Exercise in Philosophy

If there is any relevance, it is one that comes after the facts. They regard the philosophy of science as an occupation for those who are beyo ...

A Study on Reversible Logic Gates of Quantum Computing

DNA copying mechanism in a human cell dissipates about 100 kT of heat per bit copied (which is understandable from a consideration of the chemical bonds that need to be broken in the process), both far from the ideal limit of kT ln 2 for irreversible computing. That classical computation can be done ...
