PICS Colloquium: “Taking a layman’s perspective to turbulence modeling”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

Abstract: Turbulence is an unsolved problem in classical physics. Its modeling often involves physical, mathematical, and numerical concepts that are daunting to even experienced engineers. This makes it very hard for a user to take a turbulence model from the literature and apply it in real-world engineering. This talk will take a layman's perspective to […]

ESE Spring Seminar – “New Frontiers in Quantum Simulation and Computation with Neutral Atom Arrays”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Learning how to create, study, and manipulate highly entangled states of matter is key to understanding exotic phenomena in condensed matter and high energy physics, as well as to the development of useful quantum computers. In this talk, I will discuss recent experiments where we demonstrated the realization of a quantum spin liquid phase using […]

ESE Spring Seminar – “Building Photonic Systems for Extreme-Scale Computing, Particle Accelerations, and Beyond”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

A photonic-electronic system can potentially process enormous amounts of data that no stand-alone electronics have been capable of. Furthermore, a chip-scale optical atomic clock can be so precise that it only loses the equivalent of one second every million years. In the foreseeable future, highly integrated photonics can usher disruptive advances in communications, deep learning, […]

ESE Spring Seminar – “From Exact Laws to Design Principles of Quantum Information Machines”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Many-body quantum systems are the most powerful computers allowed by Nature. How do they work? Can we control them? Are they useful? In this talk, I discuss how recent results in quantum information theory translate into quantum engineering solutions. I introduce a geometric information measure that rigorously evaluates the difference between two complex configurations of arbitrarily […]

PICS Colloquium: “Preserving microscale features in continuum models of fiber network materials”

Zoom - email kathom@seas.upenn.edu

Fiber networks at different length scales represent a prevalent microstructure of highly deformable materials and biological matter. At the microscale, these fiber networks are key for the function of biological systems, while at the macroscale they endow materials with striking characteristics, such as unusual kinematic behavior and high defect tolerance. Resolving the microstructure in discrete […]

ESE Spring Seminar – “Emergent Active Photonic Platforms for Next-Generation Mid-Infrared and Ultrafast Photonics”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

As two basic properties of light, wavelength and timescale are central to numerous photonic applications. Compared to visible and near-infrared, the longer wavelength mid-infrared spectral regime contains unique thermal visual information and chemical fingerprints of the environment.  On a different front, femtosecond light sources and systems can enable ultrafast information processing, sensing, and computing. Yet, […]

ESE Spring Seminar – “Minimally Invasive and Chronically Stable Brain-Machine Interface”

Zoom - Meeting ID 992 3585 3697

Stable chronic mapping of brain activities at the action potential level with high temporal resolution is essential for both fundamental neuroscience research and biomedical applications, including cognitive studies, memory encoding and retrieval, and neural prostheses. Conventional neural probes can provide high spatiotemporal-resolution brain signal recordings independent of probing depth, although they generally trigger foreign body […]

ESE Spring Seminar – “End-to-end Learning for Robust Decision Making”

Heilmeier Hall (Room 100), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Because the physical world is complex, ambiguous, and unpredictable, autonomous agents must be engineered to exhibit a human-level degree of flexibility and generality — far beyond what we are capable of explicitly programming. Achieving such rich and intricate decision making requires rethinking the foundations of intelligence across all stages of the autonomous learning lifecycle. In […]

PICS Colloquium “The Dynamics of Gas-Particle Partitioning: Insights from Laboratory, Field, and Modeling studies”

Zoom - email kathom@seas.upenn.edu

Abstract: Ultrafine aerosols can significantly influence Earth’s climate if they are able to grow to sizes large enough to interact with the incoming solar radiation and nucleate cloud droplets. In clear air, aerosol growth occurs via gas-to-particle conversion of condensable trace gases, including sulfuric acid, nitric acid, hydrochloric acid, ammonia, and myriad oxidation products of […]

PICS Colloquium: “Transforming Healthcare from the Outside: the OBSERVER project”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

We live with a health care system that has evolved into an increasingly fragmented, primarily treatment-oriented, and now heavily burdened environment.  More importantly, issues related to privacy, space, and disease transmissibility have limited access to non-medical personnel who might offer creative, evidence-based, radical change to the health care system, as proposed years ago by the […]
