Quantum Monte Carlo simulations provide a powerful tool to compute static properties of quantum many-particle models and realistic systems. Here, the authors present a technique to reduce the computational cost of computing ground-state energies, properties, and correlation functions in the framework of the auxiliary-field quantum Monte Carlo method. This is based on a simple application of group theory, and can be readily transferred to other computational methodologies for many-particle systems.

A design paradigm of topology has recently emerged to manipulate the flow of phonons. At its heart lies a topological transition to a nontrivial state with exotic properties. This framework has been limited to linear lattice dynamics so far. Here we show a topological transition in a nonlinear regim...

Group theoretical approach to computing phonons and their interactions

By Lyuwen Fu, Mordechai Kornbluth, Zhengqian Cheng, and Chris A. Marianetti from Recent Articles in Phys. Rev. B. Published on Jul 18, 2019.

Author(s): Lyuwen Fu, Mordechai Kornbluth, Zhengqian Cheng, and Chris A. Marianetti

The authors introduce a formalism for computing phonons and their interactions based upon space group irreducible derivatives, yielding an approach that satisfies all symmetries by construction. The formalism provides the most efficient finite-displacement algorithm allowed by group theory, resulting in speedups of more than an order of magnitude compared to competing approaches. These gains will make possible the study of vibrations in far more complex materials by means of DFT in addition to allowing expensive methods beyond DFT to be employed.

An on-the-fly force field generation method is developed and applied to liquid-solid phase transitions.

Applications show that more than 99% of the expensive first-principles calculations are bypassed, and molecular dynamics simulations are accelerated by more than two orders of magnitude already during learning, with many more orders during production runs.

Author(s): Denis Golež, Lewin Boehnke, Martin Eckstein, and Philipp Werner

Cuprate superconductors remain a mysterious and intensely studied class of materials. New insights into their properties may be obtained by driving these systems out of equilibrium by strong laser pulses. Up to now, most theoretical works on photoexcited cuprates have employed a minimalistic single-band description of these complex materials. In order to treat cuprates and other charge transfer insulators more realistically, the authors develop a multiband theoretical scheme based on GW+EDMFT and Hartree-Fock+EDMFT and apply it to the paradigmatic Emery model. They demonstrate that photoexcitations across the charge transfer gap lead to a strong renormalization of this gap by relative band shifts as well as a substantial broadening of the bands. Comparison with several experimental probes on cuprates, e.g., time-resolved ARPES or optical experiments, shows a remarkable agreement with these simulation results. The new theoretical framework opens a path to explore optical manipulations in charge transfer insulators.

Quantum paramagnetism and helimagnetic orders in the Heisenberg model on the body centered cubic lattice

Author(s): Pratyay Ghosh, Tobias Müller, Francesco Parisen Toldin, Johannes Richter, Rajesh Narayanan, Ronny Thomale, Johannes Reuther, and Yasir Iqbal

It is a well-known fact that with increasing spatial dimensionality magnetic systems have a progressively higher tendency towards developing long-range magnetic order. Here, the authors investigate whether frustration could potentially counter this trend already in three dimensions. To this end, they investigate interacting spins on the body centered cubic lattice using a state-of-the-art functional renormalization group framework. The results indicate that strong frustration effects do lead to melting of the magnetic orders and have the potential to stabilize quantum spin liquid phases.

Seeing beyond the light: Vison and photon electrodynamics in quantum spin ice

By Attila Szabó and Claudio Castelnovo from Recent Articles in Phys. Rev. B. Published on Jul 15, 2019.

Author(s): Attila Szabó and Claudio Castelnovo

Quantum spin liquids are massively entangled phases of matter dominated by quantum fluctuations. While semiclassical approaches prove surprisingly powerful to study them analytically and numerically, they do not always capture the dynamical behavior and quasiparticle excitations correctly. Here, the authors develop a generic approach to obviate these problems and demonstrate its power on the example of quantum spin ice. They obtain detailed insights into the hitherto elusive vison quasiparticles in spin ice and uncover strong vison-photon interactions that may become manifest in inelastic scattering experiments.

Author(s): Efim B. Rozenbaum, Sriram Ganeshan, and Victor Galitski

Here, the authors introduce the “Lyapunovian” – a new tool to study quantum chaos. It unifies the conventional random matrix theory approach with that based on the out-of-time-ordered correlator and generalizes them. Level statistics of the Lyapunovian under appropriate projections transitions as a function of time from an uncorrelated Poisson-like distribution to the Wigner-Dyson form. This new tool connects the semiclassical Lyapunov growth at early times, when the quantum effects are weak, to universal level repulsion that hinges on strong quantum interference effects.

Bosonic condensates of exciton polaritons typically coexist and interact with an incoherent reservoir, which undermines measurements of key parameters of the condensate. Here, the authors overcome this limitation by creating a high-density polariton condensate in an optically induced box trap. In this interaction-dominated Thomas-Fermi regime, the condensate is fully separated from the reservoir, which enables a direct measurement of the polariton-polariton interaction strength. The results of the measurement are in agreement with theoretical predictions.

Utilizing a dual description of two-dimensional elasticity theory as a rank-2 tensor gauge theory, the authors show that zero-temperature quantum melting of a two-dimensional crystal differs crucially from the Halperin-Nelson thermal melting scenario. This is due to the particle number conservation symmetry enforced dislocation glide constraint, or fractonicity. The authors show that quantum crystal fluctuations favor a supersolid phase before melting can occur and, furthermore, discuss applications to the quantum melting of a vortex-lattice and charge-stripe order in a metal.

Author(s): G. J. M. Hagelaar, Z. Donko, and N. Dyatko

We demonstrate that in partially ionized plasmas, Coulomb scattering can be significantly perturbed by electron collisions with neutral gas particles, and that this effect can be incorporated in the Coulomb collision terms of the Boltzmann equation by a modification of the classical Coulomb logarith...

One-Dimensional Quasicrystals with Power-Law Hopping

By X. Deng, S. Ray, S. Sinha, G. V. Shlyapnikov, and L. Santos from Recent Articles in Phys. Rev. Lett.. Published on Jul 10, 2019.

Author(s): X. Deng, S. Ray, S. Sinha, G. V. Shlyapnikov, and L. Santos

One-dimensional quasiperiodic systems with power-law hopping, $1/{r}^{a}$, differ from both the standard Aubry-André (AA) model and from power-law systems with uncorrelated disorder. Whereas in the AA model all single-particle states undergo a transition from ergodic to localized at a critical quasi...

Author(s): Steven W. Grey, Fabrizio Scarpa, and Mark Schenk

Origami in engineering is gaining interest for its potential as deployable or shape-adaptive structures. Practical systems could employ a network of actuators distributed across the structure to induce these deformations.
