Distinguishing cancerous from non-cancerous cells through analysis of electrical noise
D. C. Lovelady, T. C. Richmond, A. N. Maggi +2
Since 1984, electric cell-substrate impedance sensing (ECIS) has been used to monitor cell behavior in tissue culture and has proven sensitive to cell morphological changes and cel…
Multiphase region of helimagnetic superlattices at low temperature in an extended six-state clock model
D. C. Lovelady, H. M. Harper, I. E. Brodsky +1
The variety of magnetic phases observed in rare-earth heterostructures at low temperatures \cite{Jehan}, such as Ho/Y, may be elucidated by an ANNNI-like model Hamiltonian. In prev…
Thermoelectric Modeling of the Non-Ohmic Differential Conductance in a Tunnel Junction containing a Pinhole
Zhongsheng Zhang, David A. Rabson
To test the quality of a tunnel junction, one sometimes fits the bias-dependent differential conductance to a theoretical model, such as Simmons's formula. Recent experimental work…
Crossover from Poisson to Wigner-Dyson Level Statistics in Spin Chains with Integrability Breaking
D. A. Rabson, B. N. Narozhny, A. J. Millis
We study numerically the evolution of energy-level statistics as an integrability-breaking term is added to the XXZ Hamiltonian. For finite-length chains, physical properties exhib…
Diagnosis and Location of Pinhole Defects in Tunnel Junctions using only Electrical Measurements
Zhongsheng Zhang, David A. Rabson
In the development of the first generation of sensors and memory chips based on spin-dependent tunneling through a thin trilayer, it has become clear that pinhole defects can have…
Applications of Group Cohomology to the Classification of Fourier-Space Quasicrystals
Benji N. Fisher, David A. Rabson
In 1962, Bienenstock and Ewald described the classification of crystalline space groups algebraically in the dual, or Fourier, space. Recently, the method has been applied to quasi…
