Abstract We show that any 2D scalar field theory compactified on a cylinder and with a Fourier expandable potential V is equivalent. in the small coupling limit. to a 1D theory involving a massless particle in a potential V and an infinite tower of free massive Kaluza-Klein (KK) modes. Moving slightly away from the deep IR region has the effect of switching on interactions between the... https://herbsdailyes.shop/product-category/brownie/
