Probing New Long-Range Interactions by Isotope Shift Spectroscopy

Probing New Long-Range Interactions by Isotope Shift Spectroscopy.

We explore a method to probe new long- and intermediate-range interactions using precision atomic isotope shift spectroscopy. We develop a formalism to interpret linear King plots as bounds on new physics with minimal theory inputs. We focus only on bounding the new physics contributions that can be calculated independently of the standard model nuclear effects. We apply our method to existing ...

Probing new light force-mediators by isotope shift spectroscopy

In this Letter we explore the potential of probing new light force-carriers, with spin-independent couplings to the electron and the neutron, using precision isotope shift spectroscopy. We develop a formalism to interpret linear King plots as bounds on new physics with minimal theory inputs. We focus only on bounding the new physics contributions that can be calculated independently of the Stan...

Probing the role of long-range interactions in the dynamics of a long-range Kitaev Chain

We study the role of long-range interactions on the non-equilibrium dynamics considering a longrange Kitaev chain in which superconducting term decays with distance between two sites in a power-law fashion characterised by an exponent α. We show that the Kibble-Zurek scaling exponent, dictating the power-law decay of the defect density in the final state reached following a slow quenching of th...

Probing protein-protein interactions by dynamic force correlation spectroscopy.

We develop a formalism for single molecule dynamic force spectroscopy to map the energy landscape of protein-protein complex (P(1)P(2)). The joint distribution P(tau(1),tau(2)) of unbinding lifetimes tau(1) and tau(2), measurable in a compression-tension cycle, which accounts for the internal relaxation dynamics of the proteins under tension, shows that the histogram of tau(1) is not Poissonian...
