Radio Labeling with Preassigned Frequencies [PDF]

SIAM Journal on Optimization, 2002
Summary: A radio labeling of a graph \(G\) is an assignment of pairwise distinct, positive integer labels to the vertices of \(G\) such that labels of adjacent vertices differ by at least \(2\). The radio labeling problem (RL) consists in determining a radio labeling that minimizes the maximum label that is used (the so-called span of the labeling). RL

Construction of optical system for an atomic clock-beyond atomic fountain

Frontiers in Physics, 2022
We demonstrate the construction of the optical system in the atomic clock-beyond atomic fountain based on 87Rb atom. The optical system includes a high-stability laser system and an optical lattice.

Radio-Frequency Single-Electron Refrigerator [PDF]

Physical Review Letters, 2007
We propose a cyclic refrigeration principle based on mesoscopic electron transport. Synchronous sequential tunnelling of electrons in a Coulomb-blockaded device, a normal metal-superconductor single-electron box, results in a cooling power of $\sim k_{\rm B}T \times f$ at temperature $T$ over a wide range of cycle frequencies $f$.

Single-Electronic Radio-Frequency Refrigerator [PDF]

Physical Review Letters, 2009
We demonstrate experimentally that a hybrid single-electron transistor with superconducting leads and a normal-metal island can be refrigerated by an alternating voltage applied to the gate electrode. The simultaneous measurement of the dc current induced by the rf gate through the device at a small bias voltage serves as an in situ thermometer.

Strategies for Managing Charge in Electron-Beam Lithography on Glass

Photonics
Optical metasurfaces fabricated via electron beam lithography (EBL) are increasingly pivotal for biosensing and bioimaging applications. However, charge accumulation on insulating glass substrates persists as a critical barrier, causing distortion of the
