We study the scattering of low-energy massless and massive minimally coupled scalar fields by an asymptotically flat traversable wormhole. We provide a comprehensive treatment of this problem offering analytic expressions for the transmission and reflection amplitudes of the corresponding effective potential and the absorption cross section of the wormhole. Our results, which are based on a recently developed dynamical formulation of time-independent scattering theory, apply to a large class of… 
Dynamical formulation of low-energy scattering in one dimension
The transfer matrix M of a short-range potential may be expressed in terms of the timeevolution operator for an effective two-level quantum system with a time-dependent nonHermitian Hamiltonian. This

Resonances in the transmission of massless scalar waves in a class of wormholes.
The propagation of massless, minimally coupled scalar waves in the curved backgrounds of a one-parameter family of wormhole geometries is investigated using numerical methods. The transmission
Electromagnetic waves in a wormhole geometry
We investigate the propagation of electromagnetic waves through a static wormhole. It is shown that the problem can be reduced to a one dimensional Schrodinger-like equation with a barrier-type
Scalar waves in a wormhole geometry.
TLDR
Both near-perfect reflection as well as transmission are found to be possible for specific choices of certain parameters in a Lorentzian wormhole.
SCALAR WAVES IN A WORMHOLE TOPOLOGY
Global monochromatic solutions of the scalar wave equation are obtained in flat wormholes of dimensions (2+1) and (3+1). The solutions are in the form of infinite series involving cylindrical and
PASSAGE OF RADIATION THROUGH WORMHOLES
TLDR
It is demonstrated that the compact signal propagates through the wormhole and the dynamics of the fields in this process for both cases: collapse of the worm hole into the black hole and for the expanding wormhole.
Traversable wormholes in four dimensions
TLDR
A wormhole solution in four dimensions that can be viewed as a pair of entangled near extremal black holes with an interaction term generated by the exchange of fermion fields and embedded in the Standard Model by making its overall size small compared to the electroweak scale.
Scalar absorption: Black holes versus wormholes
We study the absorption of massless scalar waves in a geometry that interpolates between the Schwarzschild solution and a wormhole that belongs to the Morris-Thorne class of solutions. In the middle
Traversable wormholes via a double trace deformation
A bstractAfter turning on an interaction that couples the two boundaries of an eternal BTZ black hole, we find a quantum matter stress tensor with negative average null energy, whose gravitational
Traversable asymptotically flat wormholes with short transit times
We construct traversable wormholes by starting with simple four-dimensional classical solutions respecting the null energy condition and containing a pair of oppositely charged black holes connected
