  • Harter, Andrew K.; Onanga, Franck Assogba; Joglekar, Yogesh N. (SPIE, 2016-09)
    Over the past five years, open systems with balanced gain and loss have been investigated for extraordinary properties that are not shared by their closed counterparts. Non-Hermitian, Parity-Time (PT ) symmetric Hamiltonians ...
  • Bastin, S. R.; Lee, Tony E. (AIP, 2017-01)
    There is currently intensive research into creating a large-scale quantum computer with trapped ions. It is well known that for a linear ion crystal in a harmonic potential, the ions near the center are more closely spaced ...
  • Suelzer, Joseph S.; Joglekar, Yogesh N.; Vemuri, Gautam (SPIE, 2016-09)
    We experimentally demonstrate the realization of a parity-time (PT) symmetry breaking in optically coupled semiconductor lasers (SCLs). The two SCLs are identical except for a detuning between their optical emission ...
  • Marquardt, Drew; Heberle, Frederick A.; Greathouse, Denise V.; Koeppe, Roger E., II.; Standaert, Robert F.; Van Oosten, Brad J.; Harroun, Thad A.; Kinnun, Jacob J.; Williams, Justin A.; Wassall, Stephen R.; Katsaras, John (RSC, 2016-12)
    Cholesterol is an essential biomolecule of animal cell membranes, and an important precursor for the biosynthesis of certain hormones and vitamins. It is also thought to play a key role in cell signaling processes associated ...
  • Hayes, Ellen C.; Jian, Yajun; Stoll, Stefan; Li, Lei (ACS, 2016-09)
    Spore photoproduct is a thymidine dimer formed when bacterial endospore DNA is exposed to ultraviolet (UV) radiation. The mechanism of formation of this thymidine dimer has been proposed to proceed through a radical-pair ...
  • Gavrin, Andy (AAPT, 2015-10)
    Giving our students the respect they deserve will improve their performance, our mutual interactions, and our satisfaction as teachers. This is obvious to many TPT readers, but there are times when we all, myself included, ...
  • Yin, X. Y.; Yan, Yangqian; Smith, D. Hudson (APS, 2016-10)
    Deterministic preparation of an ultracold harmonically trapped one-dimensional Fermi gas consisting of a few fermions has been realized by the Heidelberg group. Using Floquet formalism, we study the time dynamics of two- ...
  • Mosey, Aaron; Gaire, Babu; Kim, Jeongwhan; Ryu, Jong Eun; Cheng, Ruihua (AIP, 2017-01)
    Magnetically susceptible materials can serve as a basis for the directed assembly of nanoscale network devices which can be used to extract energy from phase change materials. So far, matrix production cost has been a ...
  • Lee, Tony E. (APS, 2016-10)
    Quantum simulators based on atoms or molecules often have long-range interactions due to dipolar or Coulomb interactions. We present a method based on Floquet engineering to turn a long-range interaction into a short-range ...
  • Cui, Jin-Ming; Huang, Yun-Feng; Wang, Zhao; Cao, Dong-Yang; Wang, Jian; Lv, Wei-Min; Luo, Le; del Campo, Adolfo; Han, Yong-Jian; Li, Chuan-Feng; Guo, Guang-Can (SpringerNature, 2016-09-16)
    The Kibble-Zurek mechanism is the paradigm to account for the nonadiabatic dynamics of a system across a continuous phase transition. Its study in the quantum regime is hindered by the requisite of ground state cooling. ...
  • Tsekouras, Konstantinos; Custer, Thomas C.; Jashnsaz, Hossein; Walter, Nils G.; Pressé, Steve (The American Society for Cell Biology, 2016-11-07)
    Photobleaching event counting is a single-molecule fluorescence technique that is increasingly being used to determine the stoichiometry of protein and RNA complexes composed of many subunits in vivo as well as in vitro. ...
  • Kinnun, Jacob A.; Mallikarjunaiah, K. J.; Petrache, Horia I.; Brown, Michael F. (Elsevier, 2015-01)
    This article reviews the application of solid-state ²H nuclear magnetic resonance (NMR) spectroscopy for investigating the deformation of lipid bilayers at the atomistic level. For liquid-crystalline membranes, the average ...
  • Tsekouras, Konstantinos; Siegel, Amanda P.; Day, Richard N.; Pressé, Steve (Elsevier, 2015-07-07)
    Fluorescence correlation spectroscopy (FCS) is a noninvasive technique that probes the diffusion dynamics of proteins down to single-molecule sensitivity in living cells. Critical mechanistic insight is often drawn from ...
  • Chen, Zhao-Dan; Yuan, Chun-Hua; Ma, Hong-Mei; Li, Dong; Chen, L. Q.; Ou, Z. Y.; Zhang, Weiping (OSA, 2016-08)
    Collective atomic excitation can be realized by the Raman scattering. Such a photon-atom interface can form an SU(1,1)-typed atom-light hybrid interferometer, where the atomic Raman amplification processes take the place ...
  • Lee, Tony E.; Joglekar, Yogesh N.; Richerme, Philip (APS, 2016)
    We study the transverse-field Ising model with interactions that are modulated in time. In a rotating frame, the system is described by a time-independent Hamiltonian with many-body interactions, similar to the cluster ...
  • Qiu, Cheng; Chen, Shuying; Chen, L. Q.; Chen, Bing; Guo, Jinxian; Ou, Z. Y.; Zhang, Weiping (OSA, 2016-07)
    Coherent wave splitting is crucial in interferometers. Normally, the waves after this splitting are of the same type. But recent progress in interactions between atom and light has led to the coherent conversion of photon ...
  • Liu, Nannan; Li, Jiamin; Li, Xiaoying; Ou, Z. Y. (APS, 2016-06)
    We demonstrate that a phase-insensitive parametric amplifier, when coupled to a quantum correlated source, can be used as a quantum information tap for noiseless three-way signal splitting. We find that the output signals ...
  • Qian, Peng; Gu, Zhenjie; Cao, Rong; Wen, Rong; Ou, Z. Y.; Chen, J. F.; Zhang, Weiping (APS, 2016-07)
    The temporal purity of single photons is crucial to the indistinguishability of independent photon sources for the fundamental study of the quantum nature of light and the development of photonic technologies. Currently, ...
  • Harter, Andrew K.; Joglekar, Yogesh N. (Springer, 2016)
    Lattice models with non-hermitian, parity and time-reversal (PTPT) symmetric Hamiltonians, realized most readily in coupled optical systems, have been intensely studied in the past few years. A PTPT-symmetric dimer lattice ...
  • Harter, Andrew K.; Lee, Tony E.; Joglekar, Yogesh N. (APS, 2016-06)
    Aubry-André-Harper lattice models, characterized by a reflection-asymmetric sinusoidally varying nearest-neighbor tunneling profile, are well known for their topological properties. We consider the fate of such models in ...
