Effective field theory provides a powerful framework to exploit a separation of scales in physical systems. In these lectures, we discuss some general aspects of effective field theories and their application to few-body physics. In particular, we consider an effective field theory for non-relativistic particles with resonant short-range interactions where certain parts of the interaction need to be treated nonperturbatively. As an application, we discuss the so-called pionless effective field… Expand
Dilute Fermi gas at fourth order in effective field theory
Using effective field theory methods, we calculate for the first time the complete fourth-order term in the Fermi-momentum or $k_{\rm F} a_s$ expansion for the ground-state energy of a dilute FermiExpand
Effective field theory description of halo nuclei
Nuclear halos emerge as new degrees of freedom near the neutron and proton driplines. They consist of a core and one or a few nucleons which spend most of their time in the classically-forbiddenExpand
Effective field theories for low-energy reactions
Quantum-mechanical reactions can be used to probe the nature of composite particles if relations between reaction and structure observables are known. Such correlations are, however, often hard toExpand

Interesting theories with short range interactions include QCD in the hadronic phase and cold atom systems. The scattering length in two-to-two elastic scattering process captures the most elementaryExpand
Bayesian Methods for Effective Field Theories
This thesis focuses on two complementary topics for EFT UQ using Bayesian methods— quantifying EFT truncation uncertainty and parameter estimation for LECs. Expand
Scattering length in holographic confining theories
The low-energy effective theory description of a confining theory, such as QCD, is constructed including local interactions between hadrons organized in a derivative expansion. This kind of approachExpand

Narrow resonances in effective field theory
We discuss the power counting for effective field theories with narrow resonances near a two-body threshold. Close to threshold, the effective field theory is perturbative and only one combination ofExpand
Effective theory of the triton
Abstract We apply the effective field theory approach to the three-nucleon system. In particular, we consider S=1/2 neutron–deuteron scattering and the triton. We show that in this channel a uniqueExpand
Effective field theory of short-range forces
Abstract The method of effective field theories (EFTs) is developed for the scattering of two particles at wavelengths which are large compared to the range of their interaction. It is shown that theExpand
Nucleon-nucleon scattering from effective field theory
We perform a non-perturbative calculation of the 1S0 NN scattering amplitude, using an effective field theory (EFT) expansion. The expansion we advocate is a modification of what has been usedExpand
Effective field theory for halo nuclei: shallow p-wave states
Halo nuclei are a promising new arena for studies based on effective field theory (EFT). We develop an EFT for shallow p-wave states and discuss the application to elastic nα scattering. In contrastExpand
