A path-integral formulation of the run and tumble motion and chemotaxis in Escherichia coli
C. S. Renadheer, Ushasi Roy, Manoj Gopalakrishnan
Bacteria such as Escherichia coli move about in a series of runs and tumbles: while a run state (straight motion) entails all the flagellar motors spinning in counterclockwise mode…
