Development of a Scanning Tunneling Microscope for Variable Temperature Electron Spin Resonance
Jiyoon Hwang, Denis Krylov, Robertus J. G. Elbertse +8
Recent advances in increasing the spectroscopic energy resolution in scanning tunneling microscopy (STM) have been achieved by integrating electron spin resonance (ESR) with STM. H…
Non-Abelian Landau-Ginzburg Theory of Ferromagnetic Superconductivity and Photon-Spinon Mixing
Y. M. Cho, Franklin H. Cho
We propose an effective theory of non-Abelian superconductivity, an SU(2)xU(1) extension of the Abelian Landau-Ginzburg theory, which could be viewed as an effective theory of ferr…
Investigation of Near-Surface Defects of Nanodiamonds by High-Frequency EPR and DFT Calculation
Zaili Peng, Timur Biktagirov, Franklin H. Cho +2
Nanodiamond (ND) hosting nitrogen-vacancy (NV) centers is a promising platform for quantum sensing applications. Sensitivity of the applications using NV centers in NDs is often li…
Probing Two types of Gluon Jets at LHC
Y. M. Cho, Franklin H. Cho, Pengming Zhang
We propose a simple way to test the Abelian decomposition of QCD, the existence of two types of gluons, experimentally at LHC. The Abelian decomposition decomposes the gluons to th…
Abelian Decomposition and Weyl Symmetric Effective Action of SU(3) QCD
Y. M. Cho, Franklin H. Cho
We show how to calculate the effective potential of SU(3) QCD which tells that the true minimum is given by the monopole condensation. To do this we make the gauge independent Weyl…
Gradient-based closed-loop quantum optimal control in a solid-state two-qubit system
Guanru Feng, Franklin H. Cho, Hemant Katiyar +4
Quantum optimal control can play a crucial role to realize a set of universal quantum logic gates with error rates below the threshold required for fault-tolerance. Open-loop quant…
Estimating the coherence of noise in quantum control of a solid-state qubit
Guanru Feng, Joel J. Wallman, Brandon Buonacorsi +6
To exploit a given physical system for quantum information processing, it is critical to understand the different types of noise affecting quantum control. Distinguishing coherent…
Electron spin resonance spectroscopy of small ensemble paramagnetic spins using a single nitrogen-vacancy center in diamond
Chathuranga Abeywardana, Viktor Stepanov, Franklin H. Cho +1
A nitrogen-vacancy (NV) center in diamond is a promising sensor for nanoscale magnetic sensing. Here we report electron spin resonance (ESR) spectroscopy using a single NV center i…
High-frequency and high-field optically detected magnetic resonance of nitrogen-vacancy centers in diamond
Viktor Stepanov, Franklin H. Cho, Chathuranga Abeywardana +1
We present the development of an optically detected magnetic resonance (ODMR) system, which enables us to perform the ODMR measurements of a single defect in solids at high frequen…
A high-frequency electron paramagnetic resonance spectrometer for multi-dimensional, -frequency and -phase pulsed measurements
Franklin H. Cho, Viktor Stepanov, Susumu Takahashi
We describe instrumentation for a high-frequency electron paramagnetic resonance (EPR) and pulsed electron-electron double resonance (PELDOR) spectroscopy. The instrumentation is o…
Knot Topology of Vacuum Space-Time and Vacuum Decomposition of Einstein's Theory
Y. M. Cho, Franklin H. Cho
Viewing Einstein's theory as the gauge theory of Lorentz group, we construct the most general vacuum connections which have vanishing curvature tensor and show that the vacuum spac…
