Optical forces arising from phase gradients.
We demonstrate both theoretically and experimentally that phase gradients in a light field can be used to create a new category of optical traps complementary to the more familiar intensity-gradient traps known as optical tweezers. We further show that the work done by phase-gradient forces is path dependent and briefly discuss some ramifications of this nonconservativity.
متن کاملFriction forces arising from fluctuating thermal fields
We calculate the damping of a classical oscillator induced by the electromagnetic field generated by thermally fluctuating currents in the environment. The fluctuation-dissipation theorem is applied to derive the linear-velocity damping coefficient g . It turns out that g is the result of fourth-order correlation functions. The theory is applied to a particle oscillating parallel to a flat subs...
متن کاملNuclear Forces from Lattice QCD
A method to extract nucleon-nucleon (NN) potentials from the Bethe-Salpeter amplitude in lattice QCD is presented. It is applied to the two nucleons on the lattice with quenched QCD simulations. By disentangling the mixing between the S-state and the D-state, we obtain central and tensor potentials in the leading order of the velocity expansion of the non-local NN potential. The spatial structu...
متن کاملNuclear Forces
Nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. They bind protons and neutrons (“nucleons”) into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in molecules. This is the reason why nuclear reactors produce about a million times more energy per kilo...
متن کاملTowards Density Functional Calculations from Nuclear Forces
We propose a method for microscopic calculations of nuclear groundstate properties in the framework of density functional theory (DFT). We discuss how the density functional is equivalent to the effective action for the density, thereby establishing a constructive framework for DFT calculations from nuclear forces. The presented approach starts from non-interacting nucleons in a background pote...
