Quasiparticle Properties in Effective Field Theory [PDF]
, 2002 The quasiparticle concept is an important tool for the description of many-body systems. We study the quasiparticle properties for dilute Fermi systems with short-ranged, repulsive interactions using effective field theory.

Effective Field Theory for Jet Processes [PDF]
Physical Review Letters, 2016 Processes involving narrow jets receive perturbative corrections enhanced by logarithms of the jet opening angle and the ratio of the energies inside and outside the jets. Analyzing cone-jet processes in effective field theory, we find that in addition to soft and collinear fields their description requires degrees of freedom which are simultaneously ...

Inverse bootstrapping conformal field theories
Journal of High Energy Physics, 2018 We propose a novel approach to study conformal field theories (CFTs) in general dimensions. In the conformal bootstrap program, one usually searches for consistent CFT data that satisfy crossing symmetry.

Effective Interactions are Effective Interactions [PDF]
, 2000 The subject of effective interactions is introduced and applications in both quantum mechanics and quantum field theory are presented. In particular the use of chiral perturbation theory as an effective low energy description of QCD is developed and it is argued that such methods rally are effective in both the meson and baryonic sectors.

Consistency Relations in Effective Field Theory [PDF]
, 2017 The consistency relations in large scale structure relate the lower-order correlation functions with their higher-order counterparts. They are direct outcome of the underlying symmetries of a dynamical system and can be tested using data from future ...

Complex-mass scheme and effective field theory
EPJ Web of Conferences, 2014 The complex-mass scheme applied to hadronic effective field theory is briefly introduced. Some conceptual issues and the application to the calculation of the one-loop corrections to the ρ-meson magnetic moment are discussed.

Kubo formulas for thermodynamic transport coefficients
Journal of High Energy Physics, 2018 Uncharged relativistic fluids in 3+1 dimensions have three independent thermodynamic transport coefficients at second order in the derivative expansion. Fluids with a single global U(1) current have nine, out of which seven are parity preserving.

Effective Field Theory for Cold Atoms
, 2004 Effective Field Theory (EFT) provides a powerful framework that exploits a separation of scales in physical systems to perform systematically improvable, model-independent calculations.

Field Redefinitions, T-duality and Solutions in Closed String Field Theories [PDF]
JHEP0609:001,2006, 2006 We investigate classical solutions in closed bosonic string field theory and heterotic string field theory that are obtained order by order starting from solutions of the linearized equations of motion, and we discuss the ``field redefinitions'' which relate massless fields in the string field theory side and the low energy effective theory side ...

Recent developments in effective field theory
, 2007 We will give a short introduction to the one-nucleon sector of chiral perturbation theory and will address the issue of a consistent power counting and renormalization.
