Author(s): Viktor EislerWe study the entanglement Hamiltonian for a spherical domain in the ground state of a nonrelativistic free-fermion gas in arbitrary dimensions. Decomposed into a set of radial entanglement Hamiltonians, we show that the entanglement spectrum in each sector is identical to that of a hopping chain in … [Phys. Rev. B 109, L201113]...
Author(s): T.-H. Chou, M. Först, M. Fechner, M. Henstridge, S. Roy, M. Buzzi, D. Nicoletti, Y. Liu, S. Nakata, B. Keimer, and A. CavalleriSignatures of photoinduced superconductivity have been reported in cuprate materials subjected to a coherent phonon drive. A “cold” superfluid was extracted from the transient Terahertz conductivity and was seen to...
Author(s): Fernand Denoel, Deep Chandra Joshi, Yu-Chin Huang, Girma Hailu Gebresenbut, Cesar Pay Gómez, and Roland MathieuThe dynamical magnetic properties of the icosahedral i−Tb−Cd quasicrystal (QC) were investigated by means of squid magnetometry. At low temperatures, below T∼4.5 K, we observe conventional spin glass features including aging, memory,...
Author(s): Jia Wang, Hui Hu, and Xia-Ji LiuWe have developed a microscopic many-body theory of two-dimensional coherent spectroscopy (2DCS) for a model of polarons in one-dimensional (1D) materials. Our theory accounts for contributions from all three processes: excited-state emission (ESE), ground-state bleaching (GSB), and excited-state ab… [Phys....
Author(s): Dazhe Xu, Hongbo Lou, Di Peng, Zhenfang Xing, Fujun Lan, Ziliang Yin, Fei Zhang, Lianghua Xiong, Zhidan Zeng, Hongwei Sheng, and Qiaoshi ZengThe local atomic structure has long been recognized as a predominant characteristic and key to understanding glassy structures and properties. However, the factors governing the formation and evolution...
Author(s): Victor Rosendal, Nini Pryds, Dirch H. Petersen, and Mads BrandbygeOxygen vacancies are often attributed to changes in the electronic transport for perovskite oxide materials (ABO3). Here, we use density functional theory coupled with nonequilibrium Green's functions to systematically investigate the influence of O vacancies and also A- and...
