Award winning educator and Physics Professor Michael Dubson demonstrates and describes in humorous, entertaining ways all about sound and music.
Students gain an appreciation of how beautiful classical melodies can played on sawblades, the secret of making creepy music that accompanies our favorite sci-fi films and how to crack a bull whip!
Spin glasses are canonical examples of complex matter and form a basis for describing artificial neural networks. Repeatable control over microscopic degrees of freedom might open a new window into their structure and dynamics. I will present how we achieved this at the atomic level using a quantum-optical system comprised of ultracold gases of atoms coupled via photons resonating within multimode cavities.
The Kapitza pendulum, an inverted pendulum that is inherently unstable yet dynamically stabilized by high-frequency modulation of its pivot, is perhaps the most iconic example of dynamical stabilization of a single-particle system. Dynamical stabilization in the quantum many-body regime, however, remains largely unexplored, especially from an experimental perspective. In the first part of this talk, I will discuss experiments on ultracold atoms confined using time-periodic attractive and repulsive Gaussian potentials, the time average of which is zero [1] or positive.
Continuous-variable quantum systems enable encoding complex states in fewer modes through large-scale non-Gaussian states. Motion, as a continuous degree of freedom, underlies phenomena from Cooper pair dynamics to levitated macroscopic objects. Hence, realizing high-energy, spatially extended motional states remains key for advancing quantum sensing, simulation, and foundational tests.
In the talk, I will present the following control tasks for various nonlinear mechanical systems, including trapped atoms, levitated particles, and clamped oscillators with spin-motion coupling.
Since 2019, the CUbit Quantum Seminar Series at the University of Colorado Boulder has been a cornerstone of Colorado’s rapidly expanding quantum innovation ecosystem. Each seminar brings leading quantum scientists, entrepreneurs, and technologists from around the world to campus, creating a rare forum where students, researchers, and industry partners engage directly with the people and ideas shaping the future of quantum technology.
The Department of Biochemistry invites professors and scientists from other universities and institutes to present seminars at the University of Colorado Boulder throughout the academic year. These seminars provide an opportunity for faculty and students to learn about exciting current research.

The Will Lab studies quantum systems of ultracold atoms and molecules. The lab cools atoms and molecules to temperatures less than a millionth of a degree above absolute zero, where atomic behavior is fully governed by quantum mechanics. Under these conditions, the lab controls individual quantum particles and their interactions with high precision using atomic physics tools, enabling novel platforms for many-body quantum physics, quantum simulation, quantum computing, and quantum optics.

I will discuss the standards of time and frequency and how these standards have evolved over the centuries. I will present the current definitions of time and frequency and how these definitions are likely to evolve in the coming years.
