Center for Applied Physics Science

CAPS

The Center for Applied Physics Science (CAPS) was founded in 1997 and has been identified by the University of Louisiana System as a Center of Excellence at Louisiana Tech University.  The center is located in the Engineering Annex Building and has 20,000 sq. ft. of office and laboratory space. CAPS provides a world-class research and education environment that integrates both engineering and physics disciplines, creating opportunities for interdisciplinary studies, the sharing of resources, and the transfer of technology from basic science to applications. The center brings together faculty with diverse academic backgrounds and serves the educational need of the Physics, Chemistry and Electrical Engineering Programs at Louisiana Tech University.

CAPS is one of the premium research centers on campus with current research efforts spanning diverse areas of nuclear and elementary particle physics, photonics, computational physics, materials by design, nanotechnology, and bio-physics. Our faculty is participating in large scale national and international projects hosted by the Thomas Jefferson National Accelerator Lab, the Fermi National Accelerator Lab, the European Center for Particle Physics (CERN), and LIGO (Laser Interferometric Gravitational wave Observatory). CAPS researchers lead and actively participate in collaborative research involving other centers on campus, such as the Institute for Micromanufacturing (IfM), the Trenchless Technology Center (TTC), and the Center for Biomedical Engineering and Rehabilitation Science (CBERS).

ATLAS Experiment

ATLAS (A Toroidal LHC Apparatus) is the larger of two general purpose detectors located at CERN, the European Organization for Nuclear Research, in Geneva, Switzerland. This experiment is one of the largest collaborations in particle physics consisting of 38 countries, 174 universities and labs, 3000 scientists, and approximately 1000 students. The ATLAS detector is used to collect data from the proton-proton collisions of the LHC using high-resolution calorimeters and large superconductors. Louisiana Tech is particularly interested in data captured at ATLAS, so we may

  • search for the Higgs,
  • analyze the final state of Tau lepton events,
  • refine how data is collected and jets are produced,
  • study quantum chromodynamics,
  • measure the strong coupling constant, and
  • study top quark physics.

A particle closely matching the Higgs boson has been detected at ATLAS and the other general purpose experiment CMS and was announced in July 2012. Since the original announcement and using twice the data, the confidence of the observation of the Higgs boson has risen to 10 sigma. The Chi B (3P) particle was also discovered by ATLAS and was the first particle discovered at the LHC. The LCH has been in the process of upgrading and is to begin the collection of new data at twice the energy in 2015.

Computational Physics

The ever-increasing computational capabilities have become the third pillar of science in par with theory and experiment. Scientific computation can provide a competitive edge in solving fundamental problems or developing new technological solutions. Louisiana Tech University is one of the six research institutions that form the backbone of the Louisiana Optical Network Initiative (LONI), a $50M investment in the State’s IT infrastructure. Our faculty work with top- high-performance computing (HPC) resources including the LONI’s supercomputer Queen Bee 2, ranked #46 in the world at the time of commissioning (November 20014), and the local CAPS community cluster Cerberus. The main research topics related to HPC and investigated by our faculty include

  • Grid and cloud computing,
  • Numerical methods for partial differential equations related to electromagnetic, acoustic, elastic, thermal and fluid problems,
  • Interface and inverse problems,
  • Atomic and coarse-grained simulations; multi-state models of DNA, nucleosomes, and chromatin,
  • Multi-scale simulations of organic conductors and nanostructures, and
  • Computational chemistry, structure, energetics, and reactivity of organolithium compounds; catalytic reactions of oxide clusters and surfaces.

DZero Experiment

D∅ is one of the two major experiments on the Tevatron collider at the Fermi National Accelerator Laboratory (or, Fermilab), near Batavia IL. For this project, an international collaborative team of scientists conducts research into the fundamental nature of matter. The Tevatron has commenced RunII. Louisiana Tech is partly responsible for:

 

  • designing, installing and operating the Inter Cryostat Detector (ICD) subsystem;
  • designing and building electronics for part of the D∅ Calorimeter;
  • writing software for the data acquisition systems;
  • helping to install and commission the detector next year; and
  • taking data and studying physics with the completed experiment.

LIGO

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is located in Livingston, Louisiana. LIGO is designed to open the field of gravitational-wave astrophysics through the direct detection of gravitational waves predicted by Einstein’s General Theory of Relativity. LIGO’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves from cataclysmic cosmic sources such as the mergers of pairs of neutron stars or black holes, or by supernovae. LIGO consists of two widely separated interferometers within the United States—one in Hanford, Washington and the other in Livingston, Louisiana—operated in unison to detect gravitational waves.

LIGO is a national facility for gravitational-wave research, providing opportunities for the broader scientific community to participate in detector development, observation, and data analysis. The capabilities of the LIGO detectors were greatly improved with the completion of the Advanced LIGO project in late 2014. The Advanced LIGO detectors will increase the sensitivity and observational range of LIGO by a factor of 10 over its predecessor, bringing 1000 times more galaxies into LIGO’s observational range. The design and construction of LIGO were carried out by LIGO Laboratory’s team of scientists, engineers, and staff at the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT), and collaborators from the over 80 scientific institutions worldwide that are members of the LIGO Scientific Collaboration. The responsibilities of LIGO Laboratory include operating the LIGO detectors, research, and development aimed at further improving the capabilities of the LIGO detectors, research in the fundamental physics of gravitation, astronomy, and astrophysics, and public education and outreach. LIGO is funded by the U.S. National Science Foundation and operated by the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT).

Photonics, Materials, and Sensors

The dramatic advances in nano-manufacturing have revolutionized the fields of optics and electronics. Composite materials referred to as electromagnetic metamaterials can provide the means to precisely control the flow of light and overcome previously believed physical limitations such as the diffraction of light. This is accomplished by precise nano-engineering of the composite materials which is equivalent to virtually creating new types of quasi-atoms and quasi-molecules. The potential of the field of metamaterials has been broadly recognized by the scientific community with the TIME magazine including it as one of the Top 10 Scientific Discoveries of 2008. The Center for Applied Physics Studies (CAPS) has been at the forefront of this emerging interdisciplinary field of study with our faculty working on:

  • metamaterials and electromagnetic invisibility devices,
  • optical traps and mimicking gravitational effects in the lab,
  • plasmonic and nanophotonic devices,
  • optoelectronics devices operating at switching rates up to 1THz,
  • enhanced photovoltaic elements and solar cells,
  • thermal and microwave sensors,
  • electromagnetic radiation of biological tissue and
  • sub-diffraction optical microscopy.

QWEAK Experiment

The Qweak is an international collaboration experiment at the Thomas Jefferson National Accelerator Facility in Virginia. The purpose of Qweak is to measure the weak mixing angle at high precision and look for new physics beyond the Standard Model. The weak force plays an important role in the processes of nuclear decays but is difficult to measure. Louisiana Tech University is responsible for the construction and installation of the forward tracking chamber for Qweak. Read more about the Qweak collaboration on the facility website.
