IFIRSE colloquium
Connection: https://zoom.us/j/506363139 Seminar#1 (9:00-9:45): Einstein-Podolsky-Rosen paradox, Bell inequalities, entanglement and quantum steering Speaker: Dr. Chau Nguyen, University of Siegen (Siegen, Germany) / (file is protected by a password ) In 1935, Einstein, Podolsky and Rosen described a thought experiment illustrating that quantum mechanics can deeply disturb our very intuition of locality, eventually leading them to regard quantum mechanics as being incomplete. We give a simple introduction to the Einstein-Podolsky-Rosen thought experiment, followed by insights given by Schrödinger and a short (and…

Webinar: Probing few-body nuclear dynamics vis 3H and 3He (e,e’p)pn cross-section
We will have a webinar from Dr. Dien Nguyen, MIT & J-Lab regarding to their recent publication https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.124.212501 The title and abstract are included in the following. We are interested in this work because there is a strong connection between the neutrino vs. electron interaction model in which the current & future neutrino program depends on it to explore the physics such as CP violation, mass hierarchy…Some connections can be found at Neutrino 2020 talk last week. https://indico.fnal.gov/event/43209/contributions/187820/attachments/130254/158595/200623_e4nu_neutrino2020.pdf ——————— Title:…

Webinar: A Search for Neutron-Antineutron Oscillation in the NOvA experiment
Title: A Search for Neutron-Antineutron Oscillation in the NOvA experiment Speaker: Dr. Dung Phan, Uni.v of Texas at Austin, US Abstract: Searching for neutron-antineutron oscillation is an active research direction that promises immense values for field of particle physics and cosmology. An experimental observation of the phenomenon offers the possibility of new physics associated with anomalous B and/or B − L violating processes. A data-driven trigger that allows NOvA - a long baseline neutrino oscillation experiment - to collect the…

Dr. Pham Ngoc Diep (VNSC)
Speaker: Assoc.Prof. Pham Ngoc Diep (Vietnam National Space Center) Title ALMA Dust Polarization toward Protostellar Cores and Disks Abstract: Recent advances in high-spatial-resolution polarimetric observations, in particular with ALMA, allow us to resolve the small-scale (~ 100 au) characteristics of dust polarization toward protostellar cores and disks. ALMA observations reveal the diverse properties of dust polarization with wavelengths and location, which suggests the presence of different polarization mechanisms in protostellar environments. In this talk, I will briefly review the…

Speaker: Prof. Archana Soam (India Institute of Astrophysics) Title: Threads & flows in the dusty universe: Importance of astronomical polarimetry and spectroscopy in probing star-forming regions Abstract: The role of magnetic fields (B-fields) and turbulence in star formation is still under debate, but considering the magnetized nature of molecular clouds, we expect B-fields to have a significant impact on this process. Observations of molecular clouds in different environments using different astronomical techniques helps in understanding the various important aspects…

Brandon Hensley (Princeton)
Title: The Nature of Interstellar Dust: Insights from Polarimetry Abstract: What is interstellar dust made of? In this talk, I will argue against conventional models that posit dust grains come in separate silicate and carbonaceous varieties. Rather, I will use observations of polarized dust emission to argue that grains are a mix of both silicate and carbonaceous materials, as well as other materials like metallic iron and iron oxides. Tests of this hypothesis and implications for the lifecycle of dust…

Speaker: Yue Hu (UW-Madison) Title: Characterizing 3D Magnetic Fields in Star-Forming Regions Magnetic field, turbulence, and self-gravity are important in understanding star formation. However, 3D magnetic field orientation and strength were barely accessed. Based on our recent understanding of dust polarization and anisotropic MHD turbulence, I will present two novel methods, i.e., polarization fraction analysis and velocity gradient technique (VGT), in tracing the 3D magnetic field orientation. By combing with the Davis–Chandrasekhar-Fermi method, I will show that the 3D magnetic…
