The nuclear-physics landscape has been redesigned as a sequence of effective field
theories (EFTs) connected to the standard model through symmetries and lattice simulations …

Ever since quantum field theory was first applied to the derivation of nuclear forces in the
mid-twentieth century, the renormalization of pion exchange with realistic couplings has …

We study the problem of the attractive inverse square potential in quantum mechanics with a
generalized uncertainty relation. Using the momentum representation, we show that this …

We compute 2→ 2 scattering in massive ϕ 4 theory on R 1, m× T n to NLO. We perform the
calculations using “denominator regularization” instead of the usual dimensional …

Non-Efimovian N-body resonances are investigated in the regime of a large two-body s-
wave scattering length. In view of a universal description of low-energy bound and …

A bstract Gravitational wave 'echoes' during black-hole merging events have been
advocated as possible signals of modifications to gravity in the strong-field (but …

We use a toy model to illustrate how to build effective theories for singular potentials. We
consider a central attractive 1/r2 potential perturbed by a 1/r4 correction. The power …

A bstract We show that the simplest FLRW cosmological system consisting in the homo-
geneous and isotropic massless Einstein-Scalar system enjoys a hidden conformal …

A two-level atom freely falling towards a Schwarzschild black hole was recently shown to
detect radiation in the Boulware vacuum in an insightful paper [MO Scully et al., Proc. Natl …

Exact solutions describing a fall of a particle to the centre of a non-regularized singular
potential in classical and quantum cases are obtained and compared. We inspect the …
