"Rotation-sensing atom interferometer using an atom chip"Zekun Chu , University of Virginia [Host: Cass Sackett]
ABSTRACT:
Sagnac matter-wave interferometer possesses intrinsic sensitivity for rotation sensing. In this talk, I’ll discuss the basic theory and experimental procedure of interferometry for rotation measurement, using Bose-Einstein condensates in a designed AC magnetic waveguide. Our next step plan, upgrading the system and implementing an atom chip to achieve better performance, will also be proposed here. |

"CP-Violation with Neutrino Disappearance"Peter Denton , Brookhaven National Laboratory [Host: Julian Heeck]
ABSTRACT:
The best way to probe CP violation in the lepton sector is with long-baseline accelerator neutrino experiments in the appearance mode: the appearance of νe in predominantly νμ beams. Here we show that it is possible to discover CP violation with disappearance experiments only, by combining JUNO for electron neutrinos and DUNE or Hyper-Kamiokande for muon neutrinos. While the maximum sensitivity to discover CP is quite modest (1.6σ with 6 years of JUNO and 13 years of DUNE), some values of δ may be disfavored by > 3σ depending on the true value of δ. |
