We discuss the construction of low-energy tight-binding Hamiltonians for condensed matter systems with a strong coupling to quantum electromagnetic field. Such can be obtained by projecting continuum theory on given set Wannier orbitals. However, different representations lead formulations, because may entangle light and matter, transforming orbitals into light-matter hybrid states before projection. In particular, multi-center Power-Zienau-Woolley transformation yields dipolar Hamiltonian...
Intertwined orders exist ubiquitously in strongly correlated electronic systems and lead to intriguing phenomena quantum materials. In this Letter, we explore the unique opportunity of manipulating intertwined through entangling states with light. Using a Floquet formalism study cavity-mediated interaction, show vacuum fluctuations effectively enhance charge-density-wave correlation, giving rise phase entangled order photon coherence, putative superradiant behaviors thermodynamic limit....
We show that a metastable $\eta$--pairing superconducting phase can be induced by photodoping doublons and holes into strongly repulsive fermionic Hubbard model. The doublon-hole condensate originates from an intrinsic exchange interaction does not rely on the symmetry of half-filled It extends over wide range doublon densities effective temperatures. Different non-equilibrium protocols to realize this state are proposed numerically tested. also study optical conductivity in phase, which...
This paper connects the complementary limits of manipulating quantum many-body systems with classical light and light. The authors describe two different pathways towards achieving Floquet engineering matter: (i) many-photon states at weak light-matter coupling, or (ii) few-photon strong coupling.
Grid-forming converters (GFMs) can enable power electronics to mimic the inertia response of synchronous generators (SGs), which enhance frequency stability ac grids with high penetration renewable energy sources (RESs). However, GFMs potentially induce oscillations during support because similar external dynamics SGs. In this paper, a disturbance observer-based sliding mode controller (PDOSMFC) is proposed facilitate flexible and system damping through GFMs. By leveraging intrinsic ability...
We study how strongly correlated electrons on a dissipative lattice evolve out of equilibrium under constant electric field, focusing the extent linear regime and hysteretic nonlinear effects at higher fields. access nonequilibrium steady states, nonperturbatively in both field electronic interactions, by means dynamical mean-field theory Coulomb gauge. The response regime, limited Joule heating, breaks down fields much smaller than quasiparticle energy scale. For large strong but...
Recent experiments have revealed the tantalizing possibility of fabricating lattice electronic systems strongly coupled to quantum fluctuations electromagnetic fields, e.g., by means geometry confinement from a cavity or artificial gauge fields in simulators. In this work, we develop high-frequency expansion construct effective models for electrons continuum off-resonant photon modes with arbitrary dispersion. The theory is nonperturbative light-matter coupling strength, and therefore...
An entropy cooling scheme based on electron or hole evaporation into full empty narrow bands is used to prepare several interesting nonequilibrium states of the Hubbard model: (i) cold photo-doped Mott insulating with long-lived quasiparticles, (ii) superconducting in repulsive model an inverted population, and (iii) \ensuremath{\eta}-paired systems a large density doublons holons.
Marine ecosystems are a primary conservation concern because of the separate and synergistic effects overfishing climate change on their productivity biodiversity. For purpose implementing ecosystem-based fisheries management, it is essential to understand how fish stocks respond in marine ecosystems, especially those that have been overexploited. The Beibu Gulf northwestern part South China Sea has long one China's major fishing grounds. After collapse demersal ecosystem 1990 s, small...
The interplay of light and matter gives rise to intriguing cooperative effects in quantum many-body systems. This is even true thermal equilibrium, where the electromagnetic field can hybridize with collective modes matter, virtual photons induce interactions solid. Here, we show how these light-mediated be treated using dynamical mean-field theory formalism. We consider a minimal model two-dimensional material that couples surface plasmon polariton mode metal-dielectric interface. Within...
Recent theoretical studies showed that the electronic structure of 1$T$-TaS$_2$ in low-temperature commensurate charge density wave phase exhibits a nontrivial interplay between band-insulating and Mott insulating behavior. This has important implications for interpretation photo-doping experiments. Here we use nonequilibrium dynamical mean-field theory simulations realistic multi-layer to clarify carrier dynamics induced by laser pulse. The solution is propagated up picosecond timescale...
Ultrafast photodoping of the Mott insulators, possessing strong correlation between electronic and magnetic degrees freedom, holds promise for launching an ultrafast dynamics spins which cannot be described in terms conventional models magnetism. Here we study laser-induced order a novel spin-orbit insulator Sr2IrO4 featuring uncompensated pattern antiferromagnetic spin ordering. Using transient magneto-optical Kerr effect sensitive to net magnetization, reveal that by femtosecond laser...
Long-term variations in population structure, growth, mortality, exploitation rate, and recruitment pattern of two major commercial small pelagic fishes (CSPFs) (Decapterus maruadsi Trachurus japonicus) are reported based on bottom trawl survey data collected during 2006–2020 the Beibu Gulf, South China Sea. All individuals each sampling quarter over a period 15 years were subjected to laboratory-based analysis. In this study, stock D. T. japonicus inhabiting Gulf was assessed using...
Wide-band-gap two-dimensional semiconductors have extensive applications in high-power electronics and optoelectronics the blue to ultraviolet region. In this study, we investigate electronic, mechanical, transport, photoelectric properties of $\mathrm{Sc}$X$\mathrm{I}$ (X = $\mathrm{S}$, $\mathrm{Se}$, $\mathrm{Te}$) monolayers using a first-principles method. Some conceptual nanodevices based on are constructed, such as p-n-junction diodes, field-effect transistors (FETs),...
Photodoped states are widely observed in laser-excited Mott insulators, which charge excitations quickly created and can exist beyond the duration of external driving. Despite fruitful experimental explorations, theoretical studies on microscopic models face challenge to simultaneously deal with exponentially separated time scales, especially multi-band systems, where long-time behaviors often well reach state-of-the-art numerical tools. Here, we address this difficulty by introducing a...
We present a quantum impurity solver based on pseudoparticle framework, which combines diagrammatic resummations for three-point vertex with Monte Carlo sampling of four-point vertex. This recently proposed approach (A. J. Kim et al., arXiv:2112.15549) is generalized here to fermionic problems and we discuss the technical details implementation, including time-stepping approach, updates, routines checking two-particle irreducibility also explain how information can be efficiently stored...
