The particle in a box in PT quantum mechanics and an electromagnetic analog
Anirudh Dasarthy, Joshua P. Isaacson, Katherine Jones-Smith +2
In PT quantum mechanics a fundamental principle of quantum mechanics, that the Hamiltonian must be hermitian, is replaced by another set of requirements, including notably symmetry…
An Electrostatic Analogy for Symmetron Gravity
Lillie Ogden, Katherine Jones-Smith, Harsh Mathur +1
The symmetron model is a scalar-tensor theory of gravity with a screening mechanism that suppresses the effect of the symmetron field at high densities characteristic of the solar…
Exploring extra dimensions with scalar waves
Katherine Jones-Smith, Harsh Mathur, Michael Verostek
This paper provides a pedagogical introduction to the physics of extra dimensions focussing on the ADD, Randall-Sundrum and DGP models. In each of these models, the familiar partic…
Vector Models in PT Quantum Mechanics
Katherine Jones-Smith, Rudolph Kalveks
We present two examples of non-Hermitian Hamiltonians which consist of an unperturbed part plus a perturbation that behaves like a vector, in the framework of PT quantum mechanics.…
A 'Dysonization' Scheme for Identifying Particles and Quasi-Particles Using Non-Hermitian Quantum Mechanics
Katherine Jones-Smith
In 1956 Dyson analyzed the low-energy excitations of a ferromagnet using a Hamiltonian that was non-Hermitian with respect to the standard inner product. This allowed for a facile…
Chameleon Effects on Small Scale Structure and the Baryonic Jeans Mass
Katherine Jones-Smith
In the framework of Newtonian cosmology or general relativity it is simple to derive a mass scale below which collapsed structures are relatively devoid of baryons. We examine how…
