Enlarging the magnetocaloric operating window of the Dy2NiMnO6 double perovskite
M. Balli, S. Mansouri, P. Fournier +6
In this paper, we mainly focus on the magnetic and magnetocaloric features of La2-xDyxNiMnO6 double perovskites. Their magnetocaloric properties are investigated in terms of both e…
Reflectance of Silicon Photomultipliers at Vacuum Ultraviolet Wavelengths
P. Lv, G. F. Cao, L. J. Wen +148
Characterization of the vacuum ultraviolet (VUV) reflectance of silicon photomultipliers (SiPMs) is important for large-scale SiPM-based photodetector systems. We report the angula…
Many-body recombination in insulating cuprates
Derek G. Sahota, Ruixing Liang, M. Dion +4
We study the pump-probe response of three insulating cuprates and develop a model for its recombination kinetics. The dependence on time, fluence, and both pump and probe photon en…
Efficient modeling of superconducting quantum circuits with tensor networks
Agustin Di Paolo, Thomas E. Baker, Alexandre Foley +2
We introduce an efficient tensor network toolbox to compute the low-energy excitations of large-scale superconducting quantum circuits up to a desired accuracy. We benchmark this a…
Anomalous Transition Magnetic Moments in two-dimensional Dirac Materials
Sanghita Sengupta, Madalina I. Furis, Oleg P. Sushkov +1
We show that the magnetic response of atomically thin materials with Dirac spectrum and spin-orbit interactions can exhibit strong dependence on electron-electron interactions. Whi…
Proximity effect in a heterostructure of a high superconductor with a topological insulator from Dynamical mean field theory
Xiancong Lu, David Sénéchal
We investigate the proximity effect in a heterostructure of the topological insulator (TI) \BiSe\ deposited on the HTSC material BSCCO. The latter is described by the one-band Hubb…
Algorithm for automated tuning of a quantum dot into the single-electron regime
Maxime Lapointe-Major, Olivier Germain, Julien Camirand Lemyre +4
We report an algorithm designed to perform computer-automated tuning of a single quantum dot with a charge sensor. The algorithm performs an adaptive measurement sequence of sub-si…
Measurements of electron transport in liquid and gas Xenon using a laser-driven photocathode
O. Njoya, T. Tsang, M. Tarka +153
Measurements of electron drift properties in liquid and gaseous xenon are reported. The electrons are generated by the photoelectric effect in a semi-transparent gold photocathode…
A Transfer Learning Method for Goal Recognition Exploiting Cross-Domain Spatial Features
Thibault Duhamel, Mariane Maynard, Froduald Kabanza
The ability to infer the intentions of others, predict their goals, and deduce their plans are critical features for intelligent agents. For a long time, several approaches investi…
Cost-Based Goal Recognition Meets Deep Learning
Mariane Maynard, Thibault Duhamel, Froduald Kabanza
The ability to observe the effects of actions performed by others and to infer their intent, most likely goals, or course of action, is known as a plan or intention recognition cog…
Méthodes de calcul avec réseaux de tenseurs en physique (Basic tensor network computations in physics)
Thomas E. Baker, Samuel Desrosiers, Maxime Tremblay +1
Cet article se veut un survol des réseaux de tenseurs et s'adresse aux débutants en la matière. Nous y mettons l'accent sur les outils nécessaires à l'implémentation concrète d'alg…
Seebeck coefficient in low-dimensional fluctuating charge-density-wave systems
M. Mbodji, C. Bourbonnais
We study the role of charge density-wave fluctuations on the temperature dependence of Seebeck coefficient in quasi-one dimensional conductors with a Peierls instability. The descr…

We have developed and characterized a symmetry-protected superconducting qubit that offers simultaneous exponential suppression of energy decay from charge and flux noise, and deph…
Erasable Bit Commitment from Temporary Quantum Trust
Norbert Lütkenhaus, Ashutosh S Marwah, Dave Touchette
We introduce a new setting for two-party cryptography with temporarily trusted third parties. In addition to Alice and Bob in this setting, there are additional third parties, whic…
Computing partition functions in the one clean qubit model
Anirban N. Chowdhury, Rolando D. Somma, Yigit Subasi
We present a method to approximate partition functions of quantum systems using mixed-state quantum computation. For positive semi-definite Hamiltonians, our method has expected ru…
Energy of fermionic ground states with low-entanglement single-reference expansions, and tensor-based strong-coupling extensions of the coupled-cluster method
