  • Looper, Dagny L.; Mohanty, Subhanjoy; Bochanski, John J.; Burgasser, Adam J.; Mamajek, Eric E.; Herczeg, Gregory J.; West, Andrew A.; Faherty, Jacqueline K.; Rayner, John; Pitts, Mark A.; Kirkpatrick, J. Davy (2010-05)
    TWA 30 is a remarkable young (7 ± 3 Myr), low-mass (0.12 ± 0.04 M [subscript ☉]), late-type star (M5 ± 1) residing 42 ± 2 pc away from the Sun in the TW Hydrae Association (TWA). It shows strong outflow spectral signatures ...
  • Yu, Miao; Ibrahem, Ismail; Hasegawa, Masayuki; Hoveyda, Amir H.; Schrock, Richard Royce (American Chemical Society (ACS), 2012-01)
    The first examples of catalytic enantioselective ring-opening/cross-metathesis (EROCM) reactions that involve enol ethers are reported. Specifically, we demonstrate that catalytic EROCM of several oxa- and azabicycles, ...
  • Elman, Jessica S; Shen, Keyue; Gabow, Aaron; Yarmush, Joshua; Jiao, Yunxin; Fletcher, Anne; Lee, Jungwoo; Yarmush, Martin L; Parekkadan, Biju; Milwid, Jack Miles; Li, Matthew; Manrai, Arjun Kumar; Cima, Michael J (Elsevier BV, 2016-12)
    The secreted proteins from a cell constitute a natural biologic library that can offer significant insight into human health and disease. Discovering new secreted proteins from cells is bounded by the limitations of ...
  • Clauser, Karl R.; Naba, Alexandra; Hynes, Richard O (MyJoVE Corporation, 2015-07)
    The extracellular matrix (ECM) is a complex meshwork of cross-linked proteins that provides biophysical and biochemical cues that are major regulators of cell proliferation, survival, migration, etc. The ECM plays important ...
  • Kleiman, Steven L.; Piene, Ragni; Tyomkin, Ilya (European Mathematical Society, 2011-09)
    Given a smooth family F/Y of geometrically irreducible surfaces, we study sequences of arbitrarily near T-points of F/Y; they generalize the traditional sequences of infinitely near points of a single smooth surface. We ...
  • Farahat, Waleed A.; Wood, Levi Benjamin; Zervantonakis, Ioannis; Schor, Alisha R.; Ong, Lee Ling; Neal, Devin M.; Kamm, Roger Dale; Asada, Harry (Public Library of Science, 2012-05)
    We demonstrate ensemble three-dimensional cell cultures and quantitative analysis of angiogenic growth from uniform endothelial monolayers. Our approach combines two key elements: a micro-fluidic assay that enables ...
  • Jia, Gengjie; Gunawan, Rudiyanto; Stephanopoulos, Gregory (MDPI AG, 2012-11)
    Kinetic modeling of metabolic pathways has important applications in metabolic engineering, but significant challenges still remain. The difficulties faced vary from finding best-fit parameters in a highly multidimensional ...
  • Choi, Han-Lim; Ponda, Sameera S.; Johnson, Luke B.; How, Jonathan P. (American Institute of Aeronautics and Astronautics, 2011-03)
    This work addresses the issue of network connectivity for a team of heterogeneous agents operating in a dynamic environment. The Consensus-Based Bundle Algorithm (CBBA), a distributed task allocation framework previously ...
  • Hu, Jiazhong; Chen, Wenlan; Zhang, Hao; Vendeiro, Zachary Michael; Vuletic, Vladan (American Physical Society, 2015-12)
    We consider the optical generation and characterization of entanglement in atomic ensembles under nonuniform interaction between the ensemble and an optical mode. We show that for a wide range of parameters a system of ...
  • Cotler, Jordan S.; Wilczek, Frank (IOP Publishing, 2016-05)
    We introduce quantum history states and their mathematical framework, thereby reinterpreting and extending the consistent histories approach to quantum theory. Through thought experiments, we demonstrate that our formalism ...
  • Lee, Catherine; Zhang, Zheshen; Steinbrecher, Gregory R.; Zhou, Hongchao; Mower, Jacob; Zhong, Tian; Wang, Ligong; Hu, Xiaolong; Horansky, Robert D.; Verma, Varun B.; Lita, Adriana E.; Mirin, Richard P.; Marsili, Francesco; Shaw, Matthew D.; Nam, Sae Woo; Wornell, Gregory W.; Wong, Franco N. C.; Shapiro, Jeffrey H.; Englund, Dirk Robert (American Physical Society, 2014-12)
    Quantum key distribution (QKD) enables participants to exchange secret information over long distances with unconditional security. However, the performance of today's QKD systems is subject to hardware limitations, such ...
  • Zhuang, Quntao; Zhang, Zheshen; Shapiro, Jeffrey H (American Physical Society, 2017-10)
    Lidar is a well-known optical technology for measuring a target's range and radial velocity. We describe two lidar systems that use entanglement between transmitted signals and retained idlers to obtain significant quantum ...
  • Zhang, Zheshen; Wong, Franco N. C.; Shapiro, Jeffrey H.; Mouradian, Sara L.; Wong, Franco N. C. (American Physical Society, 2015-03)
    Nonclassical states are essential for optics-based quantum information processing, but their fragility limits their utility for practical scenarios in which loss and noise inevitably degrade, if not destroy, nonclassicality. ...
  • Swingle, Brian Gordon (American Physical Society, 2010-07)
    Free fermions with a finite Fermi surface are known to exhibit an anomalously large entanglement entropy. The leading contribution to the entanglement entropy of a region of linear size L in d spatial dimensions is ...
  • He, Huan; Tiwari, Apoorv; Zheng, Yunqin; Ye, Peng; Wen, Xueda (American Physical Society, 2018-02)
    Excitations in (3+1)-dimensional [(3+1)D] topologically ordered phases have very rich structures. (3+1)D topological phases support both pointlike and stringlike excitations, and in particular the loop (closed string) ...
  • Maghrebi, Mohammad F.; Reid, M. T. Homer (American Physical Society, 2015-04)
    A dispersive medium becomes entangled with zero-point fluctuations in the vacuum. We consider an arbitrary array of material bodies weakly interacting with a quantum field and compute the quantum mutual information between ...
  • Pretko, Michael; Senthil, Todadri (American Physical Society, 2016-09)
    We here investigate the entanglement structure of the ground state of a (3+1)-dimensional U(1) quantum spin liquid, which is described by the deconfined phase of a compact U(1) gauge theory. A gapless photon is the only ...
  • Cotler, Jordan S.; Hertzberg, Mark P.; Mezei, Márk; Mueller, Mark (Springer Berlin Heidelberg, 2016-11)
    We compute the entanglement and Rényi entropy growth after a global quench in various dimensions in free scalar field theory. We study two types of quenches: a boundary state quench and a global mass quench. Both of these ...
  • Liu, Hong; Suh, Sunok Josephine (American Physical Society, 2014-03)
    We derive in detail several universal features in the time evolution of entanglement entropy and other nonlocal observables in quenched holographic systems. The quenches are such that a spatially uniform density of energy ...
  • Corkeron, Peter; Moore, Michael; van der Hoop, Julie (Wiley Blackwell, 2017-01)
    Individuals store energy to balance deficits in natural cycles; however, unnatural events can also lead to unbalanced energy budgets. Entanglement in fishing gear is one example of an unnatural but relatively common ...
