Enantiospecificity in NMR Enabled by Chirality-Induced Spin Selectivity
T. Georgiou, J. L. Palma, V. Mujica +7
Spin polarization in chiral molecules is a magnetic molecular response associated with electron transport and enantioselective bond polarization that occurs even in the absence of…
Minimal Model for Chirally Induced Spin Selectivity: Chirality, Spin-orbit coupling, Decoherence and Tunneling
Miguel Mena, Solmar Varela, Bertrand Berche +1
Here we review a universal model for chirally induced spin-selectivity (CISS) as a standalone effect occurring in chiral molecules. We tie together the results of forward scatterin…
Minimal Model for Chirally Induced Spin Selectivity: Spin-orbit coupling, tunneling and decoherence
Miguel Mena, Bertrand Berche, Ernesto Medina
Chirally Induced Spin Selectivity (CISS) is a transport phenomenon observed in both linear and non-linear regimes, where the spin-orbit coupling (SOC) acts as the key driver and el…
Electron Spin Polarization as a Predictor of Chiroptical Activity in Helical Molecules
Solmar Varela, Rafael Gutierrez, Gianaurelio Cuniberti +2
Chiral structures, breaking spatial inversion symmetry, exhibit non-zero chiroptical activity (COA) due to the interaction between their electric and magnetic responses under exter…
Spin polarization induced by decoherence in a tunneling one-dimensional Rashba model
S. Varela, M. Peralta, V. Mujica +2
Basic questions on the nature of spin polarization in two terminal systems and the way in which decoherence breaks Time-Reversal Symmetry (TRS) are analyzed. We exactly solve sever…
Radiation Modulated Spin coupling in DNA
Alexander López, Solmar Varela, Ernesto Medina
The spin activity in macromolecules such as DNA and oligopeptides, in the context of the Chiral Induced Spin Selectivity (CISS) has been proposed to be due to the atomic Spin-Orbit…

Solmar Varela, Iskra Zambrano, Bertrand Berche +2
The comment by O. Entin-Wohlman, A. Aharony, and Y. Utsumi, on our paper S. Varela, I. Zambrano, B. Berche, V. Mujica, and E. Medina, Phys. Rev. B 101, 241410(R) (2020) makes a few…
A Chirality-Based Quantum Leap
Clarice D. Aiello, Muneer Abbas, John M. Abendroth +41
Chiral degrees of freedom occur in matter and in electromagnetic fields and constitute an area of research that is experiencing renewed interest driven by recent observations of th…
Mechanically modulated spin orbit couplings in oligopeptides
Juan Daniel Torres, Raul Hidalgo, Solmar Varela +1
Recently experiments have shown very significant spin activity in biological molecules such as DNA, proteins, oligopeptides and aminoacids. Such molecules have in common their chir…
Spin-orbit interaction and spin selectivity for tunneling electron transfer in DNA
Solmar Varela, Iskra Zambrano, Bertrand Berche +2
Electron transfer (ET) in biological molecules such as peptides and proteins consists of electrons moving between well defined localized states (donors to acceptors) through a tunn…
Intrinsic Rashba coupling due to Hydrogen bonding in DNA
S. Varela, B. Montañes, F. López +4
We present an analytical model for the role of hydrogen bonding on the spin-orbit coupling of model DNA molecule. Here we analyze in detail the electric fields due to the polarizat…
DNA mechanical deformations and chiral spin selectivity
Solmar Varela, Vladimiro Mujica, Ernesto Medina
The strength of the spin-orbit interaction relevant to transport in a low dimensional structure depends critically on the relative geometrical arrangement of current carrying orbit…
