Faculty Commons, A Center for Teaching, Learning, Scholarship and Service coordinates all professional development, grants and assessment activities of faculty at New York City College of Technology. Faculty Commons adopts a programmatic approach to professional development and operates as a faculty resource and think tank where members collaborate on a variety of projects to shape curriculum, pedagogy and assessment.
The Office of Sponsored Programs (OSP) helps faculty and administrators compete for and win grants that strengthen the intellectual climate and improve the learning environment at City Tech. The office provides notices of grant opportunities and works with faculty and administrators over the life-cycle of a grant – from concept development through close-out.
The Professional Activity Report and Self-Evaluation (PARSE) is the documentation of a faculty member’s accomplishments during each academic year and cumulatively, in the three principal areas of teaching, scholarly and professional growth, and service. The PARSE serves as the basis for the annual evaluation. It is also provides faculty with an instrument to present to departmental and college review committees for reappointment, tenure, and promotion.
Physics Department presents Resonant time-symmetry breaking in classical and quantum oscillators
October 20, 2022
Presented by: Professor Mark Dykman, Michigan State University
A periodically driven system has discrete time-translation symmetry with the period of the driving. A nonlinear oscillator allows one to see peculiar features of quantum and classical fluctuations as well as tunneling and dissipation in resonantly driven systems. Generally, if a quantum system is in a Floquet state, its dynamical variables oscillate with the period of the driving. However, the discrete time-translation symmetry can be broken, the “time crystal” effect. Nonlinear oscillators, including nanomechanical systems and modes in electromagnetic cavities, can be used to study this effect beyond the familiar period doubling in strong fields en route to chaos. The “true” time-symmetry breaking is a many-body effect. We will discuss the classical phase transition into the broken-symmetry phase and, time permitting, some aspects of the quantum phase transition in dissipative and coherent systems. The transition occurs already for a comparatively weak resonant driving. We will show that, in the absence of dissipation, heating is exponentially suppressed, no many-body localization is required for this suppression.
