In this talk I analyze the construction of quantum field theory in multiply-connected spacetimes (i.e. spacetimes that contain regions with closed timelike curves (CTCs)). Additionally, I explore how particle detectors can discern the presence of CTCs in causally disconnected regions and differentiate between various spacetime topologies.
