In this work we present a very simple approach to input-output relations in optical cavities, limiting ourselves to oneand two-photon states of the field. After field quantization, we derive the non-unitary transformation between Inside and Outside annihilation and creation operators. Then we express the most general twophoton state generated by Inside creation operators, through base states ge...

No single system has been proved to be a gold standard and it is difficult to comment on the advantages of one system over another with the limited current knowledge on the effects of PCO on vision. There are few studies that actually compare the different systems of analysis. Researc...

In 1873, former slave John Washington (1838–1918) wrote his memoir, Memorys of the Past. This account includes a remarkable map that locates Washington’s experiences as a slave, his acts of resistance, and the route of his escape from bondage in 1862. Washington’s map is both a work of memory and a rare example of a subaltern cartographic practice. The act of mapping his experiences in Frederic...
