Physics 298
Speaker: Lukas Weber (RWTH Aachen)
Based on large-scale quantum Monte Carlo simulations, we examine the correlations along the edges of two-dimensional semi-infinite quantum critical Heisenberg spin-1/2 and spin-1 systems. In particular, we consider coupled quantum spin-dimer systems at their bulk quantum critical points, including... Read More »

Wednesday, March 4, 2020 - 12:00pm
Fitzpatrick Center Schiciano Auditorium Side A, room 1464
Speaker: Caitlin Howell, University of Maine
Liquid-infused surfaces inspired by the Nepenthes pitcher plant have recently been introduced as a new way to create materials with the bulk properties of solids and the surface properties of fluids. This approach is currently being used for a wide range of applications, including most prominently... Read More »

Speaker: Xiangdong Ji
Partons probed in high-energy scattering of a proton are effective field theory objects arising from the infinite momentum limit of the proton. Although the momentum and quark helicity are entirely distributed in non-zero-x partons moving along with the proton, there is a non-moving component with... Read More »

Physics 278
Speaker: MacKenzie Warren, NCSU
The detection of neutrinos from the next galactic core-collapsesupernova (CCSN) has become almost a certainty. However, most modernsimulations of core-collapse supernovae still do not include neutrinoflavor mixing, due to uncertainties in the fundamental physics andlimited computational resources....

Physics 130
Speaker: Kwang-Je Kim (University of Chicago)
** This event has been cancelled. Apologies for any inconvenience. **"Advances in the Current and Future X-ray Sources"X-rays from synchrotron radiation (SR) and free-electron lasers (FELs) have huge impact in the recent advances in various areas of science and technology. Having gone through... Read More »

Physics 130
Speaker: Haiyan Gao (Duke University Physics Department)
"The Proton Remains Puzzling"Nucleons (protons and neutrons) are the building blocks of atomic nuclei, and are responsible for more than 99% of the visible matter in the universe. Despite decades of efforts in studying its internal structure, there are still a number of puzzles surrounding the... Read More »

Physics 298
Speaker: Jedediah H. Pixley (Rutgers University)
Controlling correlations in quantum matter is one of the central questions in condensed matter. While pressure, chemical doping, or magnetic field have served as conventional tuning knobs, the ability to twist van der Waals materials has emerged as a novel scheme to engineer strong correlations and...

Physics 130
Speaker: Natalie Klco (University of Washington)
"Calculating Nature Naturally"Driven by advances in the precision control and manipulation of quantum systems, progress is being made in harnessing quantum complexity to empower a new framework of computing. With Hilbert spaces growing exponentially and a natural representation of entanglement,... Read More »

Physics 298
Speaker: Israel Klich (University of Virginia)
Tensor networks provide a useful class of variational wave functions suitable for numerical studies of ground states of quantum hamiltonian as well as certain classical problems. In spite of an extensive body of work on the subject, so far no examples have been found where tensor networks describe... Read More »
