Fundamental Limits Of Detection In The Near And Mid Infrared, Nathan Lenssen
Fundamental Limits Of Detection In The Near And Mid Infrared, Nathan Lenssen
CMC Senior Theses
The construction of the James Webb Space Telescope has brought attention to infrared astronomy and cosmology. The potential information about our universe to be gained by this mission and future infrared telescopes is staggering, but infrared observation faces many obstacles. These telescopes face large amounts of noise by many phenomena, from emission off of the mirrors to the cosmic infrared background. Infrared telescopes need to be designed in such a way that noise is minimized to achieve sufficient signal to noise ratio on high redshift objects. We will investigate current and planned space and ground based telescopes, model the noise …

Effective Field Theory Approach To Gravitationally Induced Decoherence, M. P. Blencowe
Dartmouth Scholarship
Adopting the viewpoint that the standard perturbative quantization of general relativity provides an effective description of quantum gravity that is valid at ordinary energies, we show that gravity as an environment induces the rapid decoherence of stationary matter superposition states when the energy differences in the superposition exceed the Planck energy scale.
