Ground States of the Double-Well QFT
Hui Liu, Yao Zhou, Jarah Evslin
At second order in perturbation theory, we find the ground states of the double-well quantum field theory in 1+1 dimensions. The operators which create these ground states fr…

Squeezing the Free Scalar Ground State
Yao Zhou, Hui Liu, Jarah Evslin
Consider two free Hamiltonians for the same scalar field with two different masses. Wefind a squeeze operator which maps the ground state of one to the other. The operatoris descri…
