The Chiral Potential of Phenanthriplatin and Its Influence on Guanine Binding
(American Chemical Society (ACS), 2014-01)The monofunctional platinum complex cis-[Pt(NH[subscript 3])[subscript 2]Cl(Am)][superscript +], also known as phenanthriplatin, where Am is the N-heterocyclic base phenanthridine, has promising anticancer activity. Unlike ... -
Chiral Potts spin glass in d=2 and 3 dimensions
(American Physical Society, 2016-09)The chiral spin-glass Potts system with q=3 states is studied in d=2 and 3 spatial dimensions by renormalization-group theory and the global phase diagrams are calculated in temperature, chirality concentration p, and ... -
Chiral quantum walks
(American Physical Society, 2016-04)Given its importance to many other areas of physics, from condensed-matter physics to thermodynamics, time-reversal symmetry has had relatively little influence on quantum information science. Here we develop a network-based ... -
Chiral RKKY interaction in Pr[subscript 2]Ir[subscript 2]O[subscript 7]
(American Physical Society, 2013-03)Motivated by the potential chiral spin liquid in the metallic spin ice Pr[subscript 2]Ir[subscript 2]O[subscript 7], we consider how such a chiral state might be selected from the spin-ice manifold. We propose that chiral ... -
Chiral spectrum of the universal tuned (SU(3) × SU(2) × U(1))/ℤ6 4D F-theory model
(Springer Berlin Heidelberg, 2023-02-27)Abstract We use the recently developed methods of arXiv:2108.07810 to analyze vertical flux backgrounds and associated chiral matter spectra in the 4D universal (SU(3) × SU(2) × U(1))/ℤ6 ... -
Chiral superconductivity from repulsive interactions in doped graphene
(2012-01)Chiral superconductivity, which breaks time-reversal symmetry, can exhibit a wealth of fascinating properties that are highly sought after for nanoscience applications. We identify doped graphene monolayer as a system where ... -
Chiral Supraparticles for Controllable Nanomedicine
(Wiley, 2020)Chirality is ubiquitous in nature and hard-wired into every biological system. Despite the prevalence of chirality in biological systems, controlling biomaterial chirality to influence interactions with cells has only ... -
Chiral symmetry on the edge of two-dimensional symmetry protected topological phases
(American Physical Society, 2012-12)Symmetry protected topological (SPT) states are short-range entangled states with symmetry. The boundary of a SPT phases has either gapless excitations or degenerate ground states, around a gapped bulk. Recently, we proposed ... -
Chiral Topological Phases in Designed Mechanical Networks
(Frontiers Media SA, 2019-11)Mass-spring networks (MSNs) have long been used as approximate descriptions of biological and engineered systems, from actomyosin networks to mechanical trusses. In the last decade, MSNs have re-attracted theoretical ... -
Chiral Topological Superconductors Enhanced by Long-Range Interactions
(American Physical Society, 2018-01)We study the phase diagram and edge states of a two-dimensional p-wave superconductor with long-range hopping and pairing amplitudes. New topological phases and quasiparticles different from the usual short-range model are ... -
Chiral Versus Classical Operad
(Oxford University Press (OUP), 2020)© The Author(s) 2020. Published by Oxford University Press. All rights reserved. We establish an explicit isomorphism between the associated graded of the filtered chiral operad and the classical operad, which is important ... -
Chiral vortical effect for bosons
(American Physical Society, 2017-08)The thermal contribution to the chiral vortical effect is believed to be related to the axial anomaly in external gravitational fields. We use the universality of the spin-gravity interaction to extend this idea to a wider ... -
Chirality dependence of coherent phonon amplitudes in single-wall carbon nanotubes
(American Physical Society (APS), 2011-11)We simulate the ultrafast dynamics of laser-induced coherent phonons in single-wall carbon nanotubes (SWNTs). In particular, we examine the coherent phonon amplitude of the radial breathing mode (RBM) as a function of ... -
Chirality dependent corona phase molecular recognition of DNA-wrapped carbon nanotubes
(Elsevier, 2015-08)Corona phase molecular recognition (CoPhMoRe) is a phenomenon whereby a polymer or surfactant corona phase wrapped around a nanoparticle selectively recognizes a particular molecule. The method can potentially generate ... -
Chirality-Assisted Electronic Cloaking of Confined States in Bilayer Graphene
(American Physical Society (APS), 2011-10)We show that the strong coupling of pseudospin orientation and charge carrier motion in bilayer graphene has a drastic effect on transport properties of ballistic p-n-p junctions. Electronic states with zero momentum ... -
Chirality-Dependent Second Harmonic Generation of MoS 2 Nanoscroll with Enhanced Efficiency
(American Chemical Society (ACS), 2020-09)© 2020 American Chemical Society. Materials with high second harmonic generation (SHG) efficiency and reduced dimensions are favorable for integrated photonics and nonlinear optical applications. Here, we fabricate MoS2 ... -
Chirped circular dielectric gratings for near-unity collection efficiency from quantum emitters in bulk diamond
(Optical Society of America, 2017-12)Efficient collection of fluorescence from nitrogen vacancy (NV) centers in diamond underlies the spin-dependent optical read-out that is necessary for quantum information processing and enhanced sensing applications. The ... -
