Charles Bennett, IBM Research The quantum nature of information The information revolution is based on what a physicist would call a classical view of information. Quantum effects were long regarded as a manageable nuisance for information processing, preventing information in microscopic objects from being observed or copied accurately, but are… Read More

Carla Fröhlich, North Carolina State University Astronomical Goldmines The origin of the elements is a fundamental question that has fascinated humans since the earliest days. Unprecedented observational, experimental, and computational facilities have provided a wealth of data, allowing us to tackle the question of the origin of elements to ever… Read More

Jessie Runnoe, Vanderbilt University Quasars at the intersection of multi-messenger and time-domain astronomy Recent evidence for a low-frequency gravitational wave background attributable to a cosmological population of supermassive black hole binaries opens the frontier of multi-messenger astrophysics to most massive black holes in the Universe. In this context, the combination… Read More

Joseph Kapusta, University of Minnesota Accelerator Disaster Scenarios, the Unabomber, and Scientific Risks The possibility that experiments at high-energy accelerators could create new forms of matter that would ultimately destroy the Earth has been considered several times in the past quarter century.  One consequence of the earliest of these disaster… Read More

Nadia Drake, Freelance Science Journalist From observations to headlines: the role of science journalism in sharing discoveries Scientific discoveries rarely make headlines by chance. Instead, journalists play a crucial role in translating complex research into stories that inform, engage, and inspire the public. But how do journalists choose which discoveries… Read More

Lyra Cao, Vanderbilt University The ROle of magnetic starspots in modern stellar astrophysics Stars are essential to much of astrophysics—whether as building blocks of galaxies, as courteous or cranky hosts to planets, or even as companions to more exotic objects. Our precise understanding of stellar behavior is therefore critical to… Read More

William Bialek, Princeton University physics (and a little chemistry) for maggots The development of a single cell into a fully functional organism is one of Nature’s most extraordinary phenomena. In a fruit fly, the larva—a maggot—can walk away from the discarded egg shell just 24 hours after the egg is… Read More

Rebecca Surman, University of Notre Dame The nuclear physics of multimessenger astrophysics The groundbreaking discovery of the neutron star merger event GW170817 ushered in a new era of multimessenger astrophysics. Potential and observed multimessenger signals such as gamma rays, neutrinos, and kilonovae arise from nuclear processes. Decoded properly,… Read More

Maura McLaughlin, West Virginia University Pulsar Timing Arrays: A new window on the gravitational wave universe Millisecond pulsars are rapidly rotating neutron stars with phenomenal rotational stability. Pulsar timing arrays worldwide monitor over 100 of these cosmic clocks in order to search for perturbations due to gravitational waves at nanohertz… Read More

Mengke Liu, Harvard University Quantum Materials with Reduced Dimensionality In the emerging post-Silicon era, the search for revolutionary materials necessitates principles that transcend those underpinning silicon’s success. Quantum materials with reduced dimensionality hold immense promise due to their reduced symmetry, enhanced electron correlation, and unprecedented tunability. Unlike in silicon, electrons… Read More

Matthew Day, Columbia University Optical Control over Topology in Quantum Materials The geometric texture of quantum states can shape macroscopic behaviors. In ‘topological’ systems, special geometric textures can lead to features such as dissipation-less energy transport or fractional quasi-particles which could revolutionize our computing and communication technologies. Therefore, a current… Read More

Haoning Tang, Harvard University Twisting Light with Nanomachines Optical metamaterials and quantum materials have optical properties that are widely tunable via several approaches, such as heating, electrostatic gating, and interfacial engineering such as twisting. Being able to tailor the interfacial properties in a similar real-time manner represents the next leap… Read More

Leah Weiss, University of Chicago Engineering interactions between spins and light with molecular qubits Coherent coupling of spins and light can enable photon-mediated scaling and control in quantum technologies, as demonstrated in trapped atom, ion, and solid-state spin qubits. Molecular analogs of such systems hold promise as a nascent qubit… Read More

Souvik Biswas, Stanford University Programming Quantum Materials for Next-Gen Photonics Abstract Technological breakthroughs have long been driven by our ability to understand and engineer materials at the atomic scale. Quantum materials, in particular, have recently unlocked exciting opportunities in nanophotonic systems, offering ultrafast speeds, low loss, and compact… Read More

Priya Vashishta, University of Southern California, Los Angeles Deep learning and quantum materials Dynamics Machine learning has become powerful tool in computational sciences. Among diverse applications, molecular dynamics (MD) simulation based on neural network (NN) has been attracting great attentions. With the highly accurate energy landscape encoded by ab-initio molecular… Read More
