All members of the department are invited and encouraged to attend.   The purpose of the meeting will be to make some announcements and to provide information and updates on various research, education, outreach, and administrative initiatives in the department.    As with the colloquium, a wine and cheese reception will follow.

TITLE: Multi-messenger observations of gravitational waves sources: from LIGO to Cosmic Explorer, ABSTRACT: The direct detection of gravitational waves is revolutionizing our view of the universe and has opened a new era in the field of time-domain multi-messenger astronomy. In this talk, I will summarize key open questions on the astrophysics of stellar-mass compact objects […]

TITLE: Exploring Planetary-Mass Brown Dwarfs in Young Star Clusters with JWST ABSTRACT: The discovery and characterization of free-floating planetary-mass objects (FFPMOs) is fundamental to our understanding of star and planet formation. The James Webb Space Telescope affords the opportunity to search for objects down to the opacity limit for fragmentation in nearby star-forming regions. We […]

TITLE: Energetic optimization during cell division ABSTRACT: Living systems are driven far from thermodynamic equilibrium through the continuous consumption of ambient energy. This energy is invested in the formation of complex, internal macromolecular structures and diverse spatial and temporal patterns in chemical and mechanical activities, which in turn orchestrate cell phenotypes and behaviors. This self-organization […]

Thank you to everyone who participated this past spring in the climate survey conducted by the department’s Committee on Diversity and Inclusion (CDI) in conjunction with JHU’s Office of Diversity and Inclusion. The CDI is very grateful for the valuable assistance that Christina Turner, Senior Diversity Strategist in the Office of Diversity and Inclusion, provided […]

TITLE: Mechanics of Domain Walls ABSTRACT: Domain walls, narrow regions separating domains of uniform magnetization, have a long history in the field of magnetism. As topological solitons, they present interest from the perspective of basic science and technological applications such as magnetic memory. Domain walls can be driven at speeds up to several kilometers per […]

TITLE:  The Many Frontiers of High Magnetic Field Research, ABSTRACT:  The National MagLab in the United States exists to provide magnetic fields that are more than a million times stronger than the Earth’s magnetic field to thousands of visiting researchers every year.  Why would anyone want to do such a thing?   It turns out that magnetic […]

TITLE:  Absolutely Mindboggling! ABSTRACT: The fractional quantum Hall states are among the most beautiful, the most consequential, and the best understood strongly correlated states discovered in nature. I will begin with a brief introduction to their rich phenomenology and explanation as a manifestation of the formation of a new kind of emergent particle called the […]
