Jeremy Carlo
Jeremy Carlo’s research concentrates on the coupled structural and magnetic behavior of correlated electron materials, particularly those crystallizing in the perovskite structure.    Named after the naturally occurring mineral SrTiO3, perovskites can be synthesized with nearly every element in the periodic table, and this versatility enables them to exhibit a dizzying array of properties including superconductivity, colossal magnetoresistance, unusual metal-insulator transitions, and multiferroic behavior.   One particular recent research focus is on perovskites exhibiting geometric magnetic frustration, which arises when the spatial arrangement of magnetic ions inhibits the development of magnetic order.   Frustrated materials are found to exhibit a wide variety of magnetic ground states, often driven by exotic physics due to the cancellation of simple interactions which drive magnetism in more familiar compounds.   In addition to synthesizing and characterizing samples at Villanova, his principal experimental research techniques include neutron scattering and muon spin relaxation, particle-beam techniques performed at national labs in the US and internationally, which provide detailed information about structure and magnetism, and the complex interplay between them.   Undergraduate students play a key role in these research projects, including the opportunity to travel to national labs to participate in experiments.
David Chuss

The polarization of light at wavelengths ranging from the infrared through the microwave region of the electromagnetic spectrum can uniquely probe our understanding of various astrophysical phenomena ranging from magnetic fields in the regions between stars to the nature of the beginning of the universe. A large part of this field is the development and use of cutting-edge instrumentation that expands our ability to explore the universe.

 

David Chuss is a team member on the Cosmology Large Angular Scale Surveyor (CLASS) instrument that is being constructed in the Atacama Desert in Chile. This instrument, led by Johns Hopkins University, will measure the polarization of the cosmic microwave background, the afterglow from the Big Bang, with extremely high sensitivity. This polarized pattern will provide insight into the nature of the universe a mere fraction of a second after the Big Bang and probe the physics of inflation, the early rapid exponential expansion of the universe that is thought to be responsible for the observed geometry and structure of the universe.

 

Dr. Chuss is also a team member on HAWC+, a polarimetric camera being constructed for NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA). Observations from this new instrument will increase our understanding of the role of magnetic fields in Galactic dynamics and star formation. HAWC+ will be also be used to provide new insight into the structure of the magnetic field in the Galactic center. In this region, the dynamical role of magnetic fields in the complex interaction of molecular material, dust, and magnetized plasma is an outstanding question. 

 

Hardware essential to the deployment and characterization of these instruments is developed in our VU laboratory with students playing a crucial part.  Undergraduates have the opportunity to participate in hardware development, instrument characterization, and data analysis.

Research & Interest

Condensed Matter Physics is a broad area of scientific inquiry that cuts across strict disciplinary boundaries to encompass areas of physics, chemistry, biology, materials science and engineering. 

Her research activities are in four distinct areas of condensed matter physics:

Nanoscale magnetism; fundamentals and applications to nanotechnological materials.

Cluster science; the transition from molecular to the solid-state.

Catalysis; iron-based catalysts for the production of carbon nanofibers.

Biological physics; structure-function relationships in iron containing proteins and enzymes.

She uses Mossbauer Spectroscopy to probe the electronic and magnetic structure of molecular and solid-state materials (amorphous or crystalline) in combination with SQUID (Superconducting Quantum Interference Device) magnetometry.

Farid Zamani Personal Website
Research & Interests Currently, Farid Zamani is investigating the F2 and g1 structure functions of the nucleon. The calculations are performed in light-cone frame. The physical nucleon is assumed to be a superposition of the bare nucleon plus virtual light-cone Fock states of baryon-meson pairs. The bare nucleon is assumed to be in one case composed of a diquark and a quark, and in other case no quark clusterization inside the nucleon. The initial distributions are evolved using QCD evolution. The calculated structure functions and/or sum rules will be compared with theoretical expectations and experimental observations.
