Physics Seminar: Capturing Correlated Electron and Ion Dynamics in Strong Fields

N-823

Place: Namm 823 Thursday, April 2 at 12:00 PM Presented by Dr. Neepa T. Maitra Faculty and students are welcome, light refreshments will be served. Abstract: The study of electron dynamics far from the ground-state is of increasing interest today in many applications: attosecond control and manipulation of electron and consequent ion dynamics, photovoltaic design,

Physics Seminar: Anderson Localization and Ray Modes

N-823

Place: Namm 823 April 08 at 11:00 am Presented by Prof. Klaus Ziegler Faculty and students are welcome. Abstract: Quantum transport is studied for two-dimensional Dirac particles, three-dimensional Weyl particles and a tight-binding system with a degenerate bandstructure in the presence of strong random scattering. In contrast to more conventional systems, there is no complete

Physics Seminar: Quantum Optics, Some Past and Present Trends

N-823

Place: Namm 823 April 30 at 12:00 pm Presented by Prof. Mark Hillery Faculty and students are welcome. Abstract: Quantum optics arose with the invention of the laser. Early work focussed on developing a quantum theory of the laser and on better understanding the nature of the quantized electromagnetic field. It was for this latter

Physics Seminar: Updating the Prompt Atmospheric Neutrino Background at IceCube

N-823

Place: Namm 823 Thursday, September 17 at 12:00 PM Presented by Jim Talbert Faculty and students are welcome, light refreshments will be served. Abstract: I will present an updated prediction of the flux of neutrinos arising from the prompt decay of charmed hadrons formed in collisions of cosmic rays on the upper atmosphere. This 'prompt'

Physics Seminar: Ordered vs. Disordered States of the Random-field Model in Three Dimensions

N-823

Place: Namm 823 Thursday, September 24 at 12:00 PM Presented by Prof. Dmitry Garanin Faculty and students are welcome, light refreshments will be served. Abstract: Talk reports on recent numerical investigation of the glassy behavior of random-field exchange models in three dimensions. Correlation of energy with the magnetization for different numbers of spin components has

Initiative for Interstellar Studies, UK: Kevin F. Long presents Interstellar Flight: The Perspective of Theoretical Physics

N-816 NY

The quest for the stars is an inspiring one that promises discoveries and new knowledge that has profound implications for our view of the Universe. Yet, to travel to the stars apparently requires breakthroughs in our physics and engineering knowhow. In this presentation, we examine the problem from the stand point of theoretical physics and

Physics Seminar: Spin Superfluidity in the nu=0 Quantum Hall State of Graphene

N-823

Dr. So Takei Queens College of CUNY The ground state of neutral monolayer graphene in a strong perpendicular magnetic field is believed to be the so-called canted antiferromagnetic nu=0 quantum Hall state. This state is an insulator for charge transport, but it should behave like a superfluid for transport of the spin component parallel to the

Physics Seminar: Black phosphorus and phosphorene: from 3D to 2D and back

N-823

Presented by Dr. Scott C. Warren of University of North Carolina at Chapel Hill Abstract: Phosphorene, a two-dimensional (2D) form of elemental phosphorus, has attracted considerable interest in recent years.  This interest is due, in large part, to predictions and observations of high mobility (several thousand cm2/Vs), a highly tunable band gap, anisotropic optoelectronic properties, and strong

Physics Seminar: 2D materials in the ultraclean limit: basic science and applications

N-823

NEW YORK CITY COLLEGE OF TECHNOLOGY Physics Department Center for Theoretical Physics 2D materials in the ultraclean limit: basic science and applications Presented by: Prof. James Hone Columbia University New York, NY, USA Thursday, March 02 at 1:00 PM Namm, Room 823 Abstract Two-dimensional materials offer a wide range of outstanding properties but are highly

Physics Seminar: Entangled States and Quantum Weirdness

N-823

Entangled states of many particles, which are states that cannot be factored into a product of states of individual particles, have been with us since the introduction of quantum mechanics, but were first explicitly singled out by Schroedinger in a discussion of the Einstein-Podolsky-Rosen (EPR) paradox, to discuss the extremely un-classical nature of these states
