ALL DOORS WILL LOCK TODAY !!
by Totten, Mary J 06 Mar '13

06 Mar '13

Everyone, We are doing an upgrade to our card reader system. When we start the upgrade, ALL doors to Birck will lock for about 15 minutes. We will try and man the doors as they lock to let people in. Please call me if you have any problems 496-1173 or 494-4491. Thank you, Mary Jo Totten Birck Nanotechnology Center Discovery Park/Purdue University 1205 West State Street West Lafayette, IN 47907-2057 (765) 496-1173 Your imagination is your preview of life's coming attractions" -Albert Einstein

FW: Solar Seminar Series tomorrow March 7, 2013 3:30 BRK 2001
by Turner, Jaime J 06 Mar '13

Energy Storage - Options and Opportunities Suresh V. Garimella Birck Rm. 2001 March 7, Thurs., 3:30 p.m I will briefly review the drivers for renewable and clean energy technologies, and the challenges in the widespread use of renewables. In particular, I will focus on the need for inexpensive and reliable energy storage approaches if inherently intermittent and transient renewable sources are to gain broad acceptance. As a specific example, I will tell a story from our group related to thermal energy storage in Concentrating Solar Power (CSP) plants that can decouple solar collection from power production. I will describe in some detail thermocline tank design with molten salt as the storage medium, long-term stability of such systems, integration of storage models into system-level solar power plant simulations that enable investigation of the performance in response to year-long sunlight data and power block operation, and their influence on CSP plant levelized cost of electricity. During the discussion period, I would be glad to allude to policy realities and challenges related to clean energy options.

NCN Seminar: Dr. Jan Mol, “Acceptor based qubits in silicon"
by Anthrop, Heather L 26 Feb '13

26 Feb '13

Acceptor based qubits in silicon Wednesday, March 13, 2013 11:00AM Burton Morgan Building, Room 129 Dr. Jan Mol Centre for Quantum Computation and Communication Technology University of New South Wales, Sydney, Australia Systems with spin-orbit interaction have significant potential for solid-state quantum computation. Coupling between the orbital angular momentum and the spin in the valence band of silicon opens the possibility for rapid all-electrical manipulation of an acceptor-bound spin-orbit state, while selection rules can provide a qubit basis that is protected from decoherence by time-reversal symmetry. Building on the seminal work of Kane, I will present a design for an acceptor-based quantum computer where the transitions between the working levels of the qubit can be switched on and off by manipulating the acceptor wave function. The crucial parameter here is the interface-induced energy splitting between the two Kramers doublets that make up the ground state of the undisturbed acceptor wave function. Based on fully atomistic tight binding simulations and low-temperature scanning tunnelling spectroscopy interface-split Kramers doublets of individual boron acceptors near a silicon surface are visualised and identified. The electron temperature in the sample is used as a reference to directly determine the energy splitting between the Kramers doublets as a function of acceptor depth which is found to be in good agreement with calculations. Finally, the observed energy splitting of ~4 meV effectively protects acceptor-based qubit from decoherence. About the Speaker: After graduating with a Master’s Degree in Applied Physics at the Delft University of Technology in the Netherlands I obtained my PhD Degree in Delft in 2012 studying Single Atom Electronics in the group of Prof. dr. Sven Rogge. During my time as a PhD student I moved to Sydney, Australia where I am currently working as a Postdoctoral Fellow at the Centre for Quantum Computation and Communication Technology at the University of New South Wales. My research focusses on studying single dopant atoms in silicon using Scanning Tunneling Spectroscopy with the emphasis on using dopants as building blocks for quantum computation.

FW: [Physfaculty] Tomorrow's Physics General Colloquium
by Turner, Jaime J 20 Feb '13

20 Feb '13

Physics Special Colloquium Theoretical AMO Physics Candidate: Andreas Becker, JILA Colorado University Boulder and NIST Thursday, February 21, 2013 4:00 P.M. - 5:00 P.M. PHYS room 203 [cid:image002.png@01CE0F6A.2DBA30D0]Refreshments at 3:30 P.M. in PHYS room 242 [Andreas Becker]<http://jila.colorado.edu/sites/default/files/andreas_becker_1.jpg> Tracing Electron Dynamics on the Attosecond Time Scale In the past time-resolved experiments and theoretical analysis explored molecular rotation and vibration as well as chemical reactions on the time scale of atomic motion. Recent advances in laser science led to the development of attosecond laser pulses (1 atomic unit = 24 attoseconds) which can uncover new insights in the electron dynamics in atoms and molecules on its natural time scale. I will present physical concepts behind attosecond laser technology and measurements. In particular, I will then discuss ongoing theoretical and experimental efforts to monitor and control the dynamics of an electron in the chemical bond of a molecule, using nature's most simplest molecule as an example.

Gentle reminder
by Totten, Mary J 19 Feb '13

19 Feb '13

Everyone, Just a gentle reminder to make sure you are using the kitchen sink to wash any dishes or dispose of left over drinks, ice, or coffee grounds. Please do not use the bathroom sinks or water fountains to rinse out dishes and drink containers. We have had problems with our drains being clogged up with food and coffee grounds. Please let me know if you have any questions and thank you in advance for helping keep Birck a great place to work. Thank you, Mary Jo Totten Birck Nanotechnology Center Discovery Park/Purdue University 1205 West State Street West Lafayette, IN 47907-2057 (765) 496-1173 Our attitude toward life determines life's attitude towards us. - John N.
