We report polymer composite films containing fillers comprised of quasi-one-dimensional (1D) van der Waals materials, specifically transition metal trichalcogenides 1D structural motifs that enable their exfoliation into bundles atomic threads. These nanostructures are characterized by extremely large aspect ratios up to 10^6. The composites with low loadings quasi-1D TaSe3 (below 3 vol. %) rev...

Submitted for the MAR13 Meeting of The American Physical Society Exciton-Plasmon Interaction Effects in Individual Carbon Nanotubes1 IGOR BONDAREV, AREG MELIKSETYAN, North Carolina Central University — We have recently developed a theory for the electrostatically controlled coupling between excitons and low-energy inter-band plasmons in individual semiconducting carbon nanotubes [1]. Here, we r...

We bosonize the Massive Thirring Model in 3+1D for small coupling constant and arbitrary mass. The bosonized action is explicitly obtained both in terms of a Kalb-Ramond tensor field as well as in terms of a dual vector field. An exact bosonization formula for the current is derived. The small and large mass limits of the bosonized theory are examined in both the direct and dual forms. We final...

I give a brief introduction to Luttinger liquids. Luttinger liquids are paramagnetic one-dimensional metals without Landau quasi-particle excitations. The elementary excitations are collective charge and spin modes, leading to charge-spin separation. Correlation functions exhibit power-law behavior. All physical properties can be calculated, e.g. by bosonization, and depend on three parameters ...

Nuclear magnetic resonance NMR relaxation times of geologic materials are closely related to pore geometry. In heterogeneous media, however, the details of this relationship are poorly understood because of a phenomenon known as pore coupling, which arises when diffusing protons sample multiple pores before relaxing. Laboratory experiments allow us to explore whether surface geochemistry can in...

We present a density matrix renormalization group study of the doped one-dimensional (1D) Hubbard-Su-Schrieffer-Heeger (Hubbard-SSH) model, where atomic displacements linearly modulate nearest-neighbor hopping integrals. Focusing on an optical variant model in strongly correlated limit relevant for cuprate spin chains, we examine how SSH interaction modifies model's ground- and excited-state pr...

Proposals are made to describe 1D, N = 4 supersymmetrical systems that extend SYK models by compactifying from 4D, 1 supersymmetric Lagrangians involving chiral, vector, and tensor supermultiplets. Quartic fermionic vertices generated via integrals over the whole superspace, while 2(q-1)-point superpotentials. The coupling constants in superfield arbitrary, can be chosen Gaussian random. In cas...

In general, fabrication of well-defined organic nanowires or nanobelts with controllable size and morphology is not as advanced as for their inorganic counterparts. Whereas inorganic nanowires are widely exploited in optoelectronic nanodevices, there remains considerable untapped potential in the one-dimensional (1D) organic materials. This Account describes our recent progress and discoveries ...
