160824 Integrated Neurophotonics:Nanotechnology for Massively-Parallel Mapping of Brain Activity
Integrated Neurophotonics:Nanotechnology for Massively-Parallel Mapping of Brain Activity Prof. Michael Roukes Robert M. Abbey Professor of Physics, Applied Physics, & Bioengineering California Institute of Technology 4:00 pm, Aug 24th KI Bldg. (E4), Matrix hall (2ndfloor) Abstract In2011, six U.S. scientists from different disciplines banded together,outlined a vision[1], and managed to convince the Obama administration of the unprecedented opportunity that now exists to launch a coordinated, large-scale effort to map brain…

Single-Molecule Analysis with Nanomechanical Systems Michael Roukes Robert M. Abbey Professor of Physics, Applied Physics, and Bioengineering California Institute of Technology, Pasadena, CA, 91125 USA 2016. 8. 22 (Mon) 3 PM KRISS 행정동 계단식세미나실 (Bldg. 101, Rm. 212) NEMS (nanoelectromechanical systems) now enable ultrasensitive measurement of the inertial mass of individual atoms and molecules1. We have employed NEMS devices to realize a new form of mass spectrometry (MS) enabling single-molecule…
160708 Electronic quasiparticles in the quantum dimer model
“Electronic quasiparticles in the quantum dimer model” Dr. Junhyun Lee Harvard University Jul. 08 (Fri.), 14:00 PM E6-2. 1st fl. #1323 We study a recently proposed quantum dimer model for the pseudogap metal state of the cuprates. The model contains bosonic dimers, representing a spin-singlet valence bond between a pair of electrons, and fermionic dimers, representing a quasiparticle with spin-1/2 and charge +e. By density matrix renormalization group calculations on…
160708 Isostatic magnetism
“Isostatic magnetism” Dr. Michael Lawler Binghampton Univ. / Cornell Univ. Jul. 08 (Fri.), 11:00 AM E6-2. 1st fl. #1323 Abstract: Recently, a peculiar state of mechanical (phonon) systems, known as isostatic lattices, was both proposed[1] and fabricated as a metamaterial[2]. This state is on the brink of mechanical collapse and remarkably has special topological properties that guarantee the existence of soliton-like zero modes or edge modes with open boundary conditions.…
