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 show the system of a heavy charged particle and a neutral atom can be described by a
low-energy effective field theory where the attractive 1/r 4 induced dipole potential …

A number of physical systems exhibit a particular form of asymptotic conformal invariance:
within a particular domain of distances, they are characterized by a long-range conformal …

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 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 …

An atom falling freely into a Kerr black hole in a Boulware-like vacuum is shown to emit
radiation with a Planck spectrum at the Hawking temperature. For a cloud of falling atoms …

We study the Pöschl–Teller potential V (x)= α 2 gs sinh− 2 (α x)+ α 2 gc cosh− 2 (α x), for
every value of the dimensionless parameters gs and gc, including the less usual ranges for …

It has been noticed that for a large class of cosmological models, the gauge fixing of the time-
reparametrization invariance does not completely fix the clock. Instead, the system enjoys a …

We present a polymer quantization of the− λ∕ r 2 potential on the positive real line and
compute numerically the bound state eigenenergies in terms of the dimensionless coupling …
