PUG Seminar

Whitmore 321 (IGC Lounge)

PUG Seminar

Contrary to isolated closed systems studied in most textbooks, physical systems in nature tend to interact with their environment. To make a measurement, one will need to have their system interact with a measurement device whose wavefunction is too complicated to write down. The observable universe interacts with the unobservable universe. These are examples of open quantum systems. In this talk, we will introduce dynamical maps and our approach in developing a theory for open quantum systems.

About our wordmark
Monica Rincon Ramirez

The IGC wordmark was created by Monica Rincon Ramirez while she was a graduate student at the Institute. Monica enjoys drawing new connections between fundamental theory and observations. Her graduate work included general relativity, loop quantum gravity, and quantum fields in cosmological backgrounds; her thesis focused on effective quantum corrections to gravitational phenomena from spinfoams and applications to cosmology. She received her PhD in 2024.

The wordmark symbolizes the scope of research at the IGC. The base represents quantum gravity, evoking the quantum geometrical picture from spinfoams and loop quantum gravity — approaches studied at the Center for Fundamental Theory. The middle shows galaxies embedded in a smooth surface characteristic of spacetime in general relativity and the larger physical scales studied at the Center for Theoretical and Observational Cosmology. The top curves to an extreme representing a supermassive black hole accompanied by an energetic jet, with a binary black hole pair nearby — the high-energy phenomena studied at the Center for Multimessenger Astrophysics.
