Yulia Maximenko Colorado State University, Department of Physics Abstract: The search for novel quantum phases in 2D materials is rapidly expanding: It is driven by the interest in robust quantum anomalous Hall insulators, topological superconductivity, correlated electronic states, and fractional statistics and by the prospect of quantum simulation in solid state. Unconventional, inherently quantum behavior […]

Corey Rae McRae National Institute of Standards and Technology/University of Colorado Abstract: Superconducting qubit coherence exhibits large temporal fluctuations due to strongly-coupled defects, in addition to being limited by cryogenic low-power dielectric loss. In this talk, I discuss how single qubit performance is generally understood, models and proposed sources of decoherence, and new research disentangling […]

Dennis Soldin University of Utah, Department of Physics & Astronomy Abstract: Cosmic rays are charged particles that enter the Earth's atmosphere where they interact with air molecules at energies of more than 10 times the center-of-mass energy at the Large Hadron Collider at CERN. These interactions produce particle cascades in the atmosphere, so-called extensive air […]

Michael Mooney Assistant Professor Colorado State University, Department of Physics Abstract: The Deep Underground Neutrino Experiment (DUNE) at the Long-Baseline Neutrino Facility is an international project that will be the largest particle physics experiment ever built in North America. The DUNE project will use massive liquid argon time projection chambers (LArTPCs) to address fundamental questions […]

Erica Nelson University of Colorado Abstract: The James Webb Space Telescope (JWST) has ushered in a transformative era in our understanding of our cosmic origins. While galaxies serve as a fundamental building block of the universe, yet how they formed has remained enigmatic owing to our inability to observe them at early cosmic times. Now, […]

Dave DeMille University of Chicago, Department of Physics Abstract: For decades, it had been expected that new fundamental particles, beyond those in the Standard Model, should exist with mass below ~1 TeV. Now, despite many types of experiments probing this scale, no clear evidence has emerged for their existence. This strongly motivates experiments that can […]

Obadiah Reed NREL and CU Boulder Abstract: Charge separation in organic photovoltaics appears to follow several mechanisms depending on the molecular details of the system in question. In this talk I present evidence from photoinduced absorption-detected magnetic resonance (PADMR) that charge transfer between phthalocyanine family donor molecules and a fullerene acceptor results in a driving […]

Markus B. Raschke CU Boulder, JILA Abstract: Understanding and ultimately controlling the properties of matter, from molecular to quantum systems, requires imaging the elementary excitations on their natural time and length scales. To achieve this goal, we developed scanning probe microscopy with ultrafast and shaped laser pulse excitation for multiscale spatio-temporal optical nano-imaging. In corresponding ultrafast movies, […]

JiHyun Kim University of Utah Abstract: Ultra-high energy cosmic rays (UHECRs) are energetic charged particles with E > 10^18 eV that impinge on Earth’s atmosphere from outer space. Their energies are much higher than those that can be achieved in laboratories such as the Large Hadron Collider. By exploring the nature and origin of UHECRs, […]

Joel Eaves CU Boulder Abstract: Quantum computing promises advances last seen in the digital age, but noise in quantum circuits severely limits the realization of quantum logic devices. My group […]

Jonathan Bird SUNY Buffalo Abstract: The past two decades have witnessed an explosion of interest in functional nanomaterials, whose rich physical properties reflect their reduced dimensionality, the importance of spin- […]

Shuo Sun Assistant Professor of Physics University of Colorado - Boulder Quantum Optics with Artificial Atoms Abstract: The 2023 Nobel Prize in Chemistry was awarded for the discovery and synthesis […]

Murray Holland CU Boulder Abstract: The creation of a matter-wave interferometer can be achieved by loading Bose-Einstein condensed atoms into a crystal of light formed by interfering laser beams.It has […]

Nanfang Yu Columbia University Abstract: In this talk, I will share with the audience recent and on-going work in my lab on metasurfaces and biophotonics. Metasurfaces utilize strong interactions between light and nanostructured thin films to control light with subwavelength precision. I will describe how we use metasurface as a technology platform to innovate free-space […]

Phil Richerme Indiana University at Bloomington Abstract: Calculating observable properties of quantum chemical systems is a promising application of quantum computers. While most quantum algorithms and experimental demonstrations to date have focused on calculations of electronic structure in molecules, we have recently developed a protocol to study nuclear dynamics processes as well. In this talk, […]

Lu Lu University of Wisconsin at Madison Abstract: Recent detections of neutrinos with energies above 5 PeV by the IceCube Neutrino Observatory, a cubic-kilometer detector at the South Pole, and KM3NeT, a next-generation neutrino telescope located in the Mediterranean Sea, confirm a diffuse flux at extreme energies. This includes a possible neutrino candidate with an […]
