Magnetic Resonance Force Microscopy with Overlapping Frequencies of Cantilever and Spin
Gennady P. Berman, Vladimir I. Tsifrinovich
We have studied theoretically magnetic resonance force microscopy (MRFM) with a high frequency nanomechanical cantilever when the cantilever frequency matches the resonant frequenc…
An IR Photodetector Using an Optically Cooled Micromirror as a Light Pressure Sensor
Gennady P. Berman, Boris M. Chernobrod, Alan R. Bishop +1
We consider mid-infrared (5 to 25 micrometers), optically cooled detectors based on a microcantilever sensor of the radiation pressure. A significant enhancement of sensitivity is…
Single-Spin Microscope with Sub-Nanoscale Resolution Based on Optically Detected Magnetic Resonance
Gennady P. Berman, Boris M. Chernobrod
We summarize our new scanning magnetic 3-D imaging system. This scanning system uses optically detected magnetic resonance in a single nitrogen vacancy center in a diamond nanocrys…
Continuum shell model: From Ericson to conductance fluctuations
G. L. Celardo, F. M. Izrailev, S. Sorathia +2
We discuss an approach for studying the properties of mesoscopic systems, where discrete and continuum parts of the spectrum are equally important. The approach can be applied (i)…
Transition from isolated to overlapping resonances in the open system of interacting fermions
G. L. Celardo, F. M. Izrailev, V. G. Zelevinsky +1
We study the statistical properties of resonance widths and spacings in an open system of interacting fermions at the transition between isolated and overlapping resonances, where…
On the Possibility of THz Amplification and Generation in Nano-Structures, by Means of 2D Plasma Waves
A. V. Chaplik, G. P. Berman
We discuss the possibility of THz amplification and generation in nano-structures, by means of 2D plasma waves. Numerical estimates have been made for room temperature and for suff…
Dynamical Instabilities and Deterministic Chaos in Ballistic Electron Motion in Semiconductor Superlattices
Kirill N. Alekseev, Gennady P. Berman, David K. Campbell
We consider the motion of ballistic electrons within a superlattice miniband under the influence of an alternating electric field. We show that the interaction of electrons with th…
Coherent carrier dynamics in semiconductor superlattices
Enrique Diez, Rafael Gomez-Alcala, Francisco Dominguez-Adame +2
We investigate the coherent dynamics of carriers in semiconductor superlattices driven by ac-dc electric fields. We solve numerically the time-dependent effective-mass equation for…
