The Lieb-Robinson theorem states that information propagates with a finite velocity in quantum systems on a lattice with nearest-neighbor interactions. What are the speed limits on information propagation in quantum systems with power-law interactions, which decay as\ 1/rα\ at distance\ r? Here, we present a definitive answer to this question for all exponents\ α\>2d\ and all spatial dimensions\ d. Schematically, information takes time at least\ rmin{1,α-2d}\ to propagate a distance\ r. As recent state transfer protocols saturate this bound, our work closes a decades-long hunt for optimal Lieb-Robinson bounds on quantum information dynamics with power-law interactions.

Specifically, we consider one or more two-level emitters located in the bulk region of the lattice, where for increasing magnetic field the photonic modes change from extended plane waves to circulating Landau levels. This change has a drastic effect on the resulting emitter-field dynamics, which becomes intrinsically non-Markovian and chiral, leading to the formation of strongly coupled Landau-photon polaritons. The peculiar dynamical and spectral properties of these quasiparticles can be probed with state-of-the-art photonic lattices in the optical and the microwave domain and may find various applications for the quantum simulation of strongly interacting topological models.

The superconducting phase results from the out-of-equilibrium excitation of carriers in the presence of Coulomb repulsion and is stabilized by coupling the driven semiconductor to a bosonic or fermionic thermal bath. We consider a circularly polarized light pump and show that by controlling the detuning of the pump frequency relative to the band gap, different types of chiral superconductivity would be induced. The emergence of novel superconducting states, such as the chiral p-wave pairing, results from the Floquet engineering of the interaction. This is realized by modifying the form of the Coulomb interaction by projecting it into the states that are resonant with the pump frequency. We show that the resulting unconventional pairing in our system can host topologically protected chiral bound states.

We investigate the Landau pole issue in two condensed matter systems whose long-wavelength physics is described by appropriate quantum field theories: the critical quantum magnet and Dirac fermions in graphene with long-range Coulomb interactions. The critical quantum magnet provides a classic example of a quantum phase transition, and it is well described by the phi(4) theory. We find that the irrelevant but symmetry-allowed couplings, such as the phi(6) potential, can significantly change the fate of the Landau pole in the emergent phi(4) theory. We obtain the coupled beta functions of a phi(4) + phi(6) potential at both small and large orders. Already from the one-loop calculation, the Landau pole is replaced by an ultraviolet fixed point. A Lipatov analysis at large orders reveals that the inclusion of a phi(6) term also has important repercussions for the high-order expansion of the beta functions. We also investigate the role of the Landau pole in a very different system: Dirac fermions in 2 + 1 dimensions with long-range Coulomb interactions, e.g., graphene. Both the weak-coupling perturbation theory up to two loops and a low-order large-N calculation show the absence of a Landau pole. Furthermore, we calculate the asymptotic expansion coefficients of the beta function. We find that the asymptotic coefficient is bounded by that of a pure bosonic phi(4) theory, and consequently graphene is free from Landau poles if the pure (4) theory does not manifest a Landau pole. We briefly discuss possible experiments that could potentially probe the existence of a Landau pole in these systems. Studying Landau poles in suitable condensed matter systems is of considerable fundamental importance since the relevant Landau pole energy scales in particle physics, whether it is quantum electrodynamics or Higgs physics, are completely unattainable.}, doi = {10.1103/PhysRevResearch.2.023310}, author = {Jian, Shao-Kai and Barnes, Edwin and Das Sarma, Sankar} } @article {tsai_learning_2020, title = {Learning molecular dynamics with simple language model built upon long short-term memory neural network}, journal = {Nat.

In this context, both mathematicians and physicists have developed largely independent methods for solving these models. In this paper we will combine and present results from both fields. In particular, we will discuss a class of lattices which can be realized as line graphs of other lattices, both in Euclidean and hyperbolic space. These lattices display highly unusual features including flat bands and localized eigenstates of compact support. We will use the methods of both fields to show how these properties arise and systems for classifying the phenomenology of these lattices, as well as criteria for maximizing the gaps.

The resistivity calculation is based on the Boltzmann transport theory within the relaxation-time approximation in the nearly-free-electron single-band approximation. We consider both 3D metals and 2D metals and focus on the dilute limit, i.e., low effective metallic carrier density (and hence low effective Fermi wave number k(F)) of the system. The main findings are (1) a phonon-scattering-induced linear-in-T resistivity could persist to arbitrarily low temperatures in the dilute limit independent of the Debye temperature (T-D), although, eventually, the low-T resistivity turns over to the expected Bloch-Grfineisen (BG) behavior with T-5(T-4) dependence, in 3D (2D), respectively, with the crossover temperature, T-BG, from the linear-in-T to the BG behavior, being proportional to the Fermi momentum, is small in the dilute limit; (2) because of low values of n, the phonon-induced resistivity could be very high in the system, orders of magnitude above the corresponding room temperature resistivity of ordinary metals; and (3) the resistivity shows an intrinsic saturation effect at very high temperatures (for T > T-D) and, in fact, weakly decreases with increasing T above a high crossover temperature with this crossover being dependent on both T-D and n in a nonuniversal manner-this high-temperature crossover is not directly connected with the Mott-Ioffe-Regel limit and is a reflection of phonon phase-space restriction. We discuss the qualitative trends in the resistivity as a function of temperature, density, phonon velocity, and system dimensionality. We also provide {\textquoteleft}{\textquoteleft}high-temperature{{\textquoteright}{\textquoteright}} linear-in-T resistivity results for 2D and 3D Dirac materials. Our work brings out the universal features of phonon-induced transport in dilute metals, and we comment on possible implications of our results for strange metals, emphasizing that the mere observation of a linear-in-T metallic resistivity at low temperatures or a very high metallic resistivity at high temperatures is not necessarily a reason to invoke an underlying quantum critical strange-metal behavior. Dilute metals may very well have highly unusual (compared with normal metals) transport properties arising from quantitative, but not qualitatively new, underlying physics. We discuss the temperature variation of the effective transport scattering rate showing that, for reasonable parameters, the scattering rate could be below or above k(B)T and, in particular, purely coincidentally, the calculated scattering rate happens to be k(B)T in normal metals with no implications whatsoever for the so-called Planckian behavior.

However, the precision in the epitaxial crystal growth used to fabricate QWs is on the order of the crystal monolayer (ML), higher than the current lithography techniques that are required to form QWRs and QDs. In addition, in these more dimensionally reduced systems the surface area to volume ratio is increased, and poorly terminated surfaces, due to either exposed free surface or process-related damage, diminish the quality. Coupling these problems with the fact that typically only a few QWs are used together, while typically much more QDs will be required to achieve equivalent output power, it becomes clear why progress in this area has been slow. Crystal growth techniques have been used with varying success over the last decade to produce one- and zero-dimensional structures. Colloidal systems have produced QD ensembles [1] with inhomogeneous broadening and are difficult to integrate into epitaxial systems common to solid state devices. Regrowth on patterned substrates has been used to produce QWRs [2] and the patterned regions above QWs have been used as stressors to form QDs from the QW [3]. Finally, ensembles of QDs have been formed by strainenhanced surface diffusion [4], and ordering has been observed using the (311) surface [5].
