Quasi-distributions for arbitrary non-commuting operators
J. S. Ben-Benjamin, L. Cohen
We present a new approach for obtaining quantum quasi-probability distributions, , for two arbitrary operators, and , where and are the cor…
Causality in the Fermi Problem and the Magnus expansion
J. S. Ben-Benjamin
In 1932, Fermi presented a two-atom model for determining whether quantum mechanics is consistent with causality, and concluded that indeed it is. In the late 1960's, Shirokov and…
Unruh Acceleration Radiation Revisited
J. S. Ben-Benjamin, M. O. Scully, S. A. Fulling +8
When ground-state atoms are accelerated and the field with which they interact is in its normal vacuum state, the atoms detect Unruh radiation. We show that atoms falling into a bl…
The ambiguity function and the displacement operator basis in quantum mechanics
Jonathan S Ben-Benjamin, William G Unruh
We present a method for calculating expectation values of operators in terms of a corresponding c-function formalism which is not the Wigner--Weyl position-momentum phase-space, bu…
Magnus expansion method for two-level atom interacting with few-cycle pulse
Tuguldur Begzjav, Jonathan S. Ben-Benjamin, Hichem Eleuch +3
Using the Magnus expansion to the fourth order, we obtain analytic expressions for the atomic state of a two-level system driven by a laser pulse of arbitrary shape with small puls…
Metasurface imaging with entangled photons
C. Altuzarra, A. Lyons, G. Yuan +4
Plasmonics and metamaterials have recently been shown to allow the control and interaction with non-classical states of light, a rather counterintuitive finding given the high loss…
