Title: Prototyping the Argus Optical Array: A Novel Design for Next-Gen, All-Sky, Array Telescopes In the past century, time-domain surveys have searched for events with timescales of days to minutes; however, surveys that investigate sub-second optical detections from millisecond- duration … Read more
Windows into Planetary Evolution: the Detection and Atmospheric Characterization of Young Planets A key question in exoplanet research is to understand how planets form and change throughout their lifetime. Young planets (< 1 gigayear old) are pivotal to this … Read more

Thermodynamics provides a successful theoretical framework to describe the equilibrium properties of substances and near-equilibrium processes within the linear response regime. However, our daily-life experiences, industrial processes, and almost all aspects of biology are ubiquitously far away from thermal equilibrium. First, we will briefly review the modern theory of non-equilibrium statistical mechanics and stochastic thermodynamics. Then, this framework is applied to resolve a 2000-year-old myth named the Mpemba effect. This counter-intuitive effect claimed that hot water can freeze faster than cold water. Finally, inspired by the Mpemba effect, we will briefly demonstrate the non-equilibrium design principle behind life-like intelligent materials with surprising information and energy controllability.
The scenario that has been selected as the standard cosmological model
is the Lambda Cold Dark Matter (ΛCDM), which provides a remarkable fit
to the bulk of available cosmological data. However, discrepancies among
key cosmological parameters of the model have emerged with different
statistical significance. While some portion of these discrepancies may
be due to systematic errors, their persistence across probes can
indicate a failure of the canonical ΛCDM model. I will review these
tensions, showing some interesting extended cosmological scenarios that
can alleviate them.
This event brings together employers who want to help students (undergrad and grad) from STEM majors explore various career pathways in their industries and answer questions about what they can do with their majors and career interests. Additionally, for students who are seeking internships and summer and post-graduation jobs, these companies also are available to talk about their current openings and how you can apply.
