DOI: 10.1038/s41598-025-02284-5
Abstract: Despite extensive studies on the one-dimensional Su-Schrieffer-Heeger-Hubbard (SSHH) model, the variant incorporating second-nearest neighbor hopping remains largely unexplored. Here, the topological classification of the extended SSH model is analyzed within the framework of the BDI… read more here.

DOI: 10.1063/5.0144221
Abstract: In the last two decades, the emergence of acoustic metamaterials has offered previously unimaginable possibilities for extraordinary control of sound waves. For example, various extremely light-weight sound attenuation systems based on metamaterials and phononic crystals… read more here.

DOI: 10.1063/5.0152172
Abstract: A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtain a device whose operating frequency can… read more here.

DOI: 10.1088/1367-2630/ae1633
Abstract: We study the one-dimensional non-Hermitian Su–Schrieffer–Heeger model with gain and loss at two different sublattices and tuned hopping amplitudes between nearest-neighboring sites based on periodic, linear, or exponential functions. A periodic function introduces an additional… read more here.

DOI: 10.1103/2bnf-tmtc
Abstract: Electron-phonon ($e$-ph) interactions arise in many strongly correlated quantum materials from the modulation of the nearest-neighbor hopping integrals, as in the celebrated Su-Schrieffer-Heeger (SSH) model. Nevertheless, relatively few non-perturbative studies of correlated SSH models have… read more here.

Abstract: We have theoretically investigated Su-Schrieffer-Heeger chains modelled as optical lattices (OL) loaded with exciton-polaritons. The chains have been subject to the resonant pumping of the edge site and shaken in either adiabatic or high-frequency regime.… read more here.

DOI: 10.1103/physrevb.100.104307
Abstract: In the present work we discuss the propagation of excitons across a one-dimensional Su-Schrieffer-Heeger lattice, which possesses both harmonic oscillations and weak quartic anharmonicities. When quantizing these vibrational degrees of freedom we identify several phonon-conserving… read more here.
