Are nonequilibrium effects relevant for chiral molecule discrimination?
Federico Ravera, Leonardo Medrano Sandonas, Rafael Gutierrez +2
Sensing and discriminating between enantiomers of chiral molecules remains a significant challenge in the design of sensor platforms. In the case of chemoresistive sensors, where d…
Chirality-induced Spin-Orbit Coupling and Spin Selectivity
Massimiliano Di Ventra, Rafael Gutierrez, Gianaurelio Cuniberti
We show that a spinor traveling along a one-dimensional helical path develops a spin-orbit coupling as a result of the curvature of the path. We estimate the magnitude of the assoc…
Network-theory based modeling of avalanche dynamics in percolative tunnelling networks
Vivek Dey, Steffen Kampman, Rafael Gutierrez +2
Brain-like self-assembled networks can infer and analyze information out of unorganized noisy signals with minimal power consumption. These networks are characterized by spatiotemp…
Charge migration in organic materials: Can propagating charges affect the key physical quantities controlling their motion?
C. Gollub, S. Avdoshenko, R. Gutierrez +2
Charge migration is a ubiquitous phenomenon with profound implications throughout many areas of chemistry, physics, biology and materials science. The long-term vision of designing…
Spin selective transport through helical molecular systems
R. Gutierrez, E. Diaz, R. Naaman +1
Highly spin selective transport of electrons through a helically shaped electrostatic potential is demonstrated in the frame of a minimal model approach. The effect is significant…
Vibrational effects in the linear conductance of carbon nanotubes
M. Gheorghe, R. Gutierrez, N. Ranjan +3
We study the influence of structural lattice fluctuations on the elastic electron transport in single-wall carbon nanotubes within a density-functional-based scheme. In the linear…
Conductance of a molecular junction mediated by unconventional metal-induced gap states
R. Gutierrez, G. Fagas, K. Richter +2
The conductance of a molecular junction is commonly determined by either charge-transfer-doping, where alignment of the Fermi energy to the molecular levels is achieved, or tunnell…
