    • Thermodynamic control -- an old paradigm with new applications 

      Deffner, Sebastian; Bonança, Marcus V. S. (2020-06-24)
      Tremendous research efforts have been invested in exploring and designing so-called shortcuts to adiabaticity. These are finite-time processes that produce the same final states that would result from infinitely slow ...
    • Thermodynamic length for far-from-equilibrium quantum systems 

      Deffner, Sebastian; Lutz, Eric (American Physical Society (APS), 2013-02-28)
      We consider a closed quantum system initially at thermal equilibrium and driven by arbitrary external parameters. We derive a lower bound on the entropy production which we express in terms of the Bures angle between the ...
    • Thermodynamic universality of quantum Carnot engines 

      Gardas, Bartłomiej; Deffner, Sebastian (American Physical Society (APS), 2015-10-12)
      The Carnot statement of the second law of thermodynamics poses an upper limit on the efficiency of all heat engines. Recently, it has been studied whether generic quantum features such as coherence and quantum entanglement ...
    • Thermodynamics of Statistical Anyons 

      Myers, Nathan M.; Deffner, Sebastian (Thermodynamics of Statistical Anyons, 2021-02-22)
      In low-dimensional systems, indistinguishable particles can display statistics that interpolate between bosons and fermions. Signatures of these "anyons" have been detected in two-dimensional quasiparticle excitations of ...
    • The Third Catalog of Active Galactic Nuclei detected by the Fermi Large Area Telescope 

      Ojha, Roopesh; Hewitt, J. W.; et al. (The American Astronomical Society, 2015-08-25)
      The third catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT (3LAC) is presented. It is based on the third Fermi-LAT catalog (3FGL) of sources detected between 100 MeV and 300 GeV with a Test Statistic ...
    • Third quantization of the electromagnetic field 

      Franson, J.D. (2021-02-28)
      We consider an approach in which the usual wave function in the quadrature representation of mode j of the electromagnetic field is quantized to produce a field operator. Since the electromagnetic field is already second ...
    • Third-Order Nonlinear Optical Properties of ALD Grown TiO2 Thin Films 

      Kuis, R.; Basaldua, I.; Burkins, P.; Kropp, J. A.; Gougousi, T.; Johnson, A. M. (Optical Society of America, 2019-09-15)
      Nonlinear index values as high as 1±.1x10-9 cm2/W were measured of ALD based TiO2 films. The 1000-fold increase in the index is believed to be due to the incorporation of nitrogen during growth.
    • Third-Order Nonlinear Optical Properties of ALD Grown TiO₂ Films by Thermally Managed Z-scan Method 

      Basaldua, I.; Burkins, P.; Kuis, R.; Kropp, J. A.; Gougousi, T.; Johnson, A. M. (Optical Society of America, 2018)
      Thermally managed Z-scan performed on ALD grown TiO₂ films demonstrated n₂ values of 1.7×10⁻¹¹ and 1.94 × 10⁻¹⁰cm²/W for films grown at 100°C and 250°C, respectively – greater than 1000X that of other growth methods.

B.; Trifonov, T.; Udry, S.; Vanderburg, A.; Wheatley, P. J.; Wingham, G.; Zhan, Z.; Ziegler, C. (EDP Sciences, 2020-07-13)
      We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI-129, TIC-201248411) is an ultra-short-period Jupiter orbiting a ...

      Iorio, Lorenzo; Pavlis, Erricos C. (The Geodetic Society of Japan, 2001-03-25)
    • Time-bin-entangled photon holes 

      Liang, J.; Franson, J.D.; Pittman, T. B. (American Physical Society (APS), 2012-11-28)
      The general concept of entangled photon holes is based on a correlated absence of photon pairs in an otherwise constant optical background. Here we consider the specialized case when this background is confined to two ...
    • Time-dependent Optical Spectroscopy of GRB 010222: Clues to the Gamma-Ray Burst Environment 

      Mirabal, N.; Halpern, J. P.; Kulkarni, S. R.; Castro, S.; Bloom, J. S.; Djorgovski, S. G.; Galama, T. J.; Harrison, F. A.; Frail, D. A.; Price, P. A.; Reichart, D. E.; Ebeling, H.; Bunker, A.; Dawson, S.; Dey, A.; Spinrad, H.; Stern, D. (IOP, 2002-07-01)
      We present sequential optical spectra of the afterglow of GRB 010222 obtained 1 day apart using the Low-Resolution Imaging Spectrometer (LRIS) and the Echellette Spectrograph and Imager (ESI) on the Keck Telescopes. Three ...
    • Time-Rescaling of Dirac Dynamics: Shortcuts to Adiabaticity in Ion Traps and Weyl Semimetals 

      Roychowdhury, Agniva; Deffner, Sebastian (MDPI, 2021-01-08)
      Only very recently, rescaling time has been recognized as a way to achieve adiabatic dynamics in fast processes. The advantage of time-rescaling over other shortcuts to adiabaticity is that it does not depend on the ...
    • Tip-enhanced strong coupling spectroscopy, imaging, and control of a single quantum emitter 

      Park, Kyoung-Duck; May, Molly A.; Leng, Haixu; Wang, Jiarong; Kropp, Jaron A.; Gougousi, Theodosia; Pelton, Matthew; Raschke, Markus B. (2019-02-27)
      Optical cavities can enhance and control light-matter interactions. This has recently been extended to the nanoscale, and with single emitter strong coupling regime even at room temperature using plasmonic nano-cavities ...
    • Total Peroxy Nitrates (ΣPNs) in the atmosphere: the Thermal Dissociation-Laser Induced Fluorescence (TD-LIF) technique and comparisons to speciated PAN measurements

    • Toward a New Paradigm for the Unification of Radio Loud AGN and its Connection to Accretion 

      Georganopoulos, Markos; Meyer, Eileen T.; Fossati, Giovanni; Lister, Matthew L. (2011-11-21)
      We recently argued (Meyer 2011) that the collective properties of radio loud active galactic nuclei point to the existence of two families of sources, one of powerful sources with single velocity jets and one of weaker ...
    • Towards a Mass-Consistent Methodology for Realistic Melting Hydrometeor Retrieval 

      Kuo, Kwo-Sen; Loftus, Adrian M; Olson, William S; Schrom, Robert S; Johnson, Benjamin T; Adams, Ian S (IEEE, 2021-02-17)
      To address the acute challenge posed by the melting layer to accurate surface precipitation retrievals from space, we ensure the compositional consistency in ice, liquid, and total masses of synthetic melting hydrometeors ...
