Wednesday, July 1, 2020 - 10:00am
Speaker: Harald W. Griesshammer
Compton scattering probes the symmetries and strengths of nucleonic and nuclear interactions and provides a bridge between data and lattice-QCD computations of fundamental hadron properties. The polarizabilities of the nucleon parametrize its stiffness against deformations in electric and magnetic... Read More »

Speaker: Xin Zhang (Duke University)
I show that a second-order phase transition can exist in a surprisingly simple system, which is a single non-linear oscillator. This simple system can be seen as a paradigmatic example of open quantum many-body system, in which there has been great interest recently due to experimental advances... Read More »

Physics 130
Speaker: Joel Moore (UC Berkeley and Lawrence Berkeley National Laboratory)
** This event had been canceled. **"Topological Aspects of Electromagnetic Response in Metals"This talk begins with an introduction to how topological phases of electrons can generate quantized responses and emergent particles such as Weyl fermions. Various insulating topological phases are known... Read More »

Physics 130
Speaker: Frank N. von Hippel (Princeton)
** Canceled. **"Reducing the danger from nuclear weapons. How physicists can help"Most of us thought that, with the end of the Cold War and the rise of democracy in Russia, the danger of a nuclear Armageddon had receded and what remained was to pilot a glide path to very a low level of de-alerted...

Speaker: Crystal Noel, Postdoctoral fellow at the Joint Quantum Institute, University of Maryland
We present the system design and architecture of a trapped-ion universal quantum processor with high-fidelity quantum gates and addressing of up to 32 qubits. Our approach takes advantage of individual optical addressing to achieve simultaneous high-fidelity operations on a long chain of 171Yb+... Read More »
Tuesday, April 7, 2020 - 12:00pm
Fitzpatrick Center Schiciano Auditorium Side A, room 1464
Speaker: Harm-Anton Klok
The first part of this lecture centers around the use of surface-initiated, controlled radical polymerization for the preparation of thin, surface tethered polymer films ("polymer brushes"). We will show that chain stretching of surface-grafted polymers in good solvents amplifies the tension at... Read More »
Monday, April 6, 2020 - 7:30pm
Gross Hall, Ahmadieh Family Auditorium, Room 107
Speaker: Professor Paul Steinhardt (Princeton University, Albert Einstein Professor in Science, Department of Physics)
This lecture is hosted by the Duke University Chemistry and Physics Departments.
Thursday, April 2, 2020 - 12:00pm
Webcast
Speaker: Xing He (Duke University)
The quantum paraelectric behavior and strongly anharmonic lattice dynamics of SrTiO3 have attracted interest for decades. Reflecting the incipient ferroelectric (FE) instability near the quantum critical point and couplings between transverse acoustic (TA) and optic (TO) phonons, anomalous phonon... Read More »
Thursday, April 2, 2020 - 11:30am
Webcast
Speaker: Volker Blum (Duke University)
Layered 2d hybrid organic-inorganic perovskites (HOIPs) can be created by combining a wide range of possible inorganic components with an even broader range of organic molecules, offering considerable flexibility to fine-tune their synthesizability and properties. This talk focuses on computational... Read More »
