Found 11 papers in prb We investigate the melting properties of the bcc refractory metals V and W, and the disordered equiatomic VW alloy from first principles. We show that thermal vibrations have a large impact on the electronic density of states (DOS) and thus considerably affect the electronic contribution to the free… We theoretically investigate the steady-state transmission of continuous terahertz (THz) wave across a freestanding ferroelectric slab. Based on the Landau-Ginzburg-Devonshire theory of ferroelectrics and the coupled equations of motion for polarization and electromagnetic (EM) waves, we derive the … Lattice vibrations can greatly reduce the charge-carrier mobilities of organic semiconductors by introducing dynamic structural disorder. The low-frequency regime is expected to contribute the most to this disorder since these vibrational modes result in the largest structural distortions and electr… Recently, the Kitaev Heisenberg model has attracted considerable interest as a description of Kitaev materials. On the honeycomb lattice, it has a phase diagram containing two spin-liquid and four magnetically ordered phases. Here, the authors consider this model on a lattice that breaks bipartite symmetry, frustrating the formation of antiferromagnetic order. Using mean field theory and DMRG, they find that this leads to the formation of two novel valence bond solid phases with a rich topological phase diagram and protected edge modes. Strong long-range hoppings up to third-nearest neighbors may induce a topological phase transition in one-dimensional chains. Unlike the Su-Schrieffer-Heeger model, this transition from trivial to topological phase occurs with the emergence of a pseudospin valley structure and a twofold nontrivial t… To add to the rapidly progressing field of ultrafast photocurrent, we propose a universal method to generate photocurrent in normal and topological materials using a pair of multicycle linearly polarized laser pulses. The interplay of the fundamental and its second harmonic pulses is studied for the… Among the family of odd-parity topological superconductors derived from ${\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$, ${\mathrm{Cu}}_{x}{(\mathrm{PbSe})}_{5}{({\mathrm{Bi}}_{2}{\mathrm{Se}}_{3})}_{6}$ (CPSBS) has been elucidated to have gap nodes. Although the nodal gap structure has been established by spe… Photocarrier dynamics of the ${\mathrm{ZrTe}}_{3}$ under pressure are investigated using optical pump-probe (OPOP) spectroscopy in combination with a diamond anvil cell. A prominent laser heating effect is manifested, characterized by significant changes in the profiles and an elongation of the echo… In this study, we use a full tight-binding model to explore the behavior of graphene nanobubbles between the interface of twisted bilayer graphene (TBG-$1.{05}^{∘}$), uncovering the simultaneous existence of confined states and pseudo-Landau level (pLL) states under minor strain conditions. We find … Topologically protected boundary transport is a promising route to realize robust quantum manipulation between distant nodes. Conventional topological transports require a long transmission time to meet adiabatic evolution, which unfortunately becomes a significant obstacle for practical quantum sys… Non-Hermitian systems exhibit diverse graph patterns of energy spectra under open boundary conditions. Here, we present an algebraic framework to comprehensively characterize the spectral geometry and graph topology of non-Bloch bands. Using a locally defined potential function, we unravel the spect…
