Confined and Deconfined Spinon Excitations in the Rectangular-lattice Quantum Antiferromagnet

Henrik Moodysson Rønnow, Bruce Normand, Ellen Fogh, Noore Elahi Shaik

Fractionalization remains one of the most fascinating manifestations of strong interactions in quantum many-body systems. In quantum magnetism, the existence of spinons-collective magnetic excitations that behave as quasiparticles with fractional quantum n ...

Higher Equations of Motion for Boundary Liouville Conformal Field Theory from the Ward Identities

Baptiste Yves Philippe Cerclé

In this document we prove higher equations of motion at the level 2 for boundary Liouville Conformal Field Theory. As a corollary we present a new derivation of the Belavin–Polyakov–Zamolodchikov differential equations. Our method of proof does not rely on ...

Sub-20 kHz low-frequency noise near ultraviolet butt-coupled fiber Bragg grating external cavity laser diode

Nicolas Grandjean, Raphaël Butté

We present a butt-coupled InGaN fiber Bragg grating (FBG) semiconductor laser diode operating below 400 nm in the single-mode emission regime. This compact coherent laser source exhibits an intrinsic linewidth of 14 kHz in the near-UV range and a side-mode ...

Quantum circuits for solving local fermion-to-qubit map- pings

Giuseppe Carleo, Jannes Willy E. Nys

Local Hamiltonians of fermionic systems on a lattice can be mapped onto local qubit Hamiltonians. Maintaining the lo-cality of the operators comes at the ex-pense of increasing the Hilbert space with auxiliary degrees of freedom. In order to retrieve the l ...

Exciton-polariton dynamics of the single site-controlled quantum dot-nanocavity in the coexisting strong-weak coupling regime

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Alessio Massimiliano Davide Miranda

Deterministic positioning single site-controlled high symmetric InGaAs quantum dots (QDs) in (111)B-oriented GaAs photonic crystal cavities with nanometer-scale accuracy provides an idea component for building integrated quantum photonic circuits. However, ...

Xor-And-Inverter Graphs for Quantum Compilation

Giovanni De Micheli, Mathias Soeken, Giulia Meuli

Quantum compilation is the task of translating a high-level description of a quantum algorithm into a sequence of low-level quantum operations. We propose and motivate the use of Xor-And-Inverter Graphs (XAG) to specify Boolean functions for quantum compil ...

On leave from

Jean-Philippe Brantut

Atomtronics is an emerging field that aims to manipulate ultracold atom moving in matter-wave circuits for fundamental studies in both quantum science and technological applications. In this Colloquium, recent progress in matter-wave circuitry and atomtron ...

Nonperturbative test of consistency relations and their violation

Angelo Esposito

In this paper, we verify the large scale structure consistency relations using N-body simulations, including modes in the highly nonlinear regime. These relations (pointed out by Kehagias & Riotto and Peloso & Pietroni) follow from the symmetry of the dyna ...

Two- to three-dimensional crossover in a dense electron liquid in silicon

Gabriel Aeppli

Doping of silicon via phosphine exposures alternating with molecular beam epitaxy overgrowth is a path to Si:P substrates for conventional microelectronics and quantum information technologies. The technique also provides a well-controlledmaterial for syst ...
