Abstract: The anthropic principle implies that life can emerge and be sustained only in a narrow range of values of fundamental constants. We show that anthropic arguments can set powerful constraints on transient variations of the fine-structure constant alpha (or, colloquially, speed of light) over the past 4 billion years since the appearance of lifeforms on Earth.

Abstract: Quantum-based electronics is a rapidly accelerating technology, where information is encoded in the quantum mechanical states of coupled natural or artificial atoms. To unlock the exceptional potential of quantum computers, one of the key challenges that the field has to overcome is to preserve the coherence of a quantum superposition over extended times.
Abstract: This tutorial will introduce computational imaging as a broad range of techniques in which algorithms play a major role in the final image formation process. The basic recipe for computational imaging involves coming up with a forward model that can simulate/predict what your imaging system measures. This model is computationally inverted to reconstruct the object under investigation. We will also discuss how to incorporate prior knowledge and constructs from machine learning into the computational reconstruction algorithms to improve the image reconstruction fidelity.
Abstract: Modern electronics rely heavily on technology that confines electrons in the interface layers of semiconductors. In recent years, scientists have discovered that they can isolate various atomically thin van der Waals (vdW) layered materials.

The Exploring Social Identities workshop is an hour long workshop designed for participants to recognize their own intersecting identities and those of others, while learning to be empathetic and open-minded to the experiences of others. This workshop will include in-depth conversations as well as tasty snacks. Hope to see you all there!

Abstract: Black holes provide a window into quantum gravity through their thermodynamic properties. Recently, it has been discovered that higher topology solutions provide additional information about the UV and play an essential role in its consistency. I will discuss how these solutions are used to study statistical properties of the quantum theory, and describe the example of thin-shell wormholes, which are used to understand the coarse-grained entropy of black holes formed by gravitational collapse.
Abstract: I will discuss recent insights into the physics of particle acceleration based on spacecraft observations of shocks associated with fast coronal mass ejections (CMEs). The acceleration of charged particles to high energies is a fundamental topic in plasma astrophysics. High energy particles themselves are useful probes of processes occurring far from Earth, either near the solar atmosphere, in the outer heliosphere, or in distant astrophysical sources, such as supernovae blasts.

Abstract: To describe an entangled state of n particles, we formally need an amount of classical information that grows exponentially with n. But given that almost all the information disappears on measurement, in what sense was it "really there"?
Synopsis: Andreotti has worked to understand hematopoietic cell signaling to understand cell signaling pathways such as T cell receptors by working on substrate binding and catalytic activity of families of protein tyrosine kinases ( IL2-inducible tyrosine kinase (Itk)). The lab uses NMR spectroscopy to determine 3D structures of various protein domains and examine interactions between domains.
