Spring Seminar Series

Join us as Amlan Biswas of Florida University gives a talk entitled:

Dielectrophoretic Behavior in Electronically Phase Separated Manganite Thin Films

Competing ferromagnetic metallic (FMM) and insulating phases in the manganite (La1-yPry)1-xCaxMnO3 (LPCMO) leads to a phase separated state in which micrometer scale FMM regions behave in a fluid-like manner over a narrow temperature range (Fig. 1). I will discuss our experimental results which show that an electric field can realign the fluid-like FMM phases embedded in an insulating matrix resulting in anisotropic in-plane resistance in microstructures of LPCMO thin films. Time and voltage dependent resistance measurements show that the dynamic percolation of the FMM regions leads to an insulator to metal transition due to electric field induced realignment of the FMM regions which is analogous to the dielectrophoresis of metallic particles suspended in fluid media. In-plane strain anisotropy plays an important role in determining the speed of dynamic percolation of the FMM regions by modifying the local electric fields in the phase separated state. I will also show that small magnetic fields (~100 Oe) can significantly modify the dielectrophoretic behavior. These observations suggest an unconventional form of magnetoelectric coupling.

Physics Café – Thursday February 6 2014 7:00 PM – 8:30 PM – Emerson Suites - Free and open to the public.

Matthew Price of the Ithaca College Department of Physics & Astronomy talks about:

The Particle Zoo: The Newest Exhibit, the Higgs Boson.

Recent discoveries at the Large Hadron Collider have helped to find the elusive Higgs Boson have led to the 2013 Nobel Prize in Physics being awarded to Francois Englert and Peter Higgs. Professor Matthew Price will be speaking about the Standard Model of Particle Physics and the newest addition to the particle zoo. We will explore the past, present and future of particle physics now that the most elusive particle has been confirmed.

Doctor Price is an Assistant Professor in the Ithaca College Department of Physics and has worked in Particle Physics, Astrophysics, Solid State Physics, and Physics Education. He has worked on understanding the structure of the proton as well as understanding how students think about physics.

Please join us for a talk with Frans Pretorius, Department of Physics, Princeton University:

 

Black Holes and Fundamental Physics

 

Black holes are perhaps the most remarkable prediction of Einstein's theory of general relativity. They are one-way membranes in the fabric of space and time, hiding singularities that exert infinitely strong tidal forces. I will begin by giving a brief history of the development of our theoretical understanding of black holes, and the astronomical discoveries that lead to the realization that they likely exist in the universe and play an important role in many astrophysical processes. As if this were not enough, over the past few years theoretical advances inspired by string theory are suggesting that general relativity, and in particular black holes "know" much more about fundamental physics that just gravity. This includes connections between black holes and thermodynamics, hydrodynamics and even quantum field theory.  I will give a few of examples of this. I do not know whether there are deeper physical or philosophical reasons for these connections, though these examples hint that black holes could be become a cornerstone of 21st century physics.

Fall Seminar Series - Please join us for a talk wtih Monica Lilly, Northrop Grumman

Monica Lilly received her undergraduate degree from the University of Maryland College Park where she studied the fabrication and testing of electron doped superconductors.   After graduation she pursued a masters at University of  CA, Riverside with a master project based in the integration of carbon nanotubes as templates for one dimensional superconductors.   For the past five years she has been working at Northrop Grumman as a process engineer, lab manager, and now principle investigator of the carbon nanotube field effect transistor project.

Her talk will focus on using semiconducting carbon nanotubes in radio frequency electronics: what can they be used for and why is the radio frequency industry interested in a one-dimensional semiconductor?  She will also discuss the process of growing carbon nanotubes and turning them into transistors.
