Computing Green's functions and improving ground state energy estimation on quantum computers with Liouvillian recursion
Jérôme Leblanc, Olivier Nahman-Lévesque, Julien Forget +3
We present a quantum-classical hybrid implementation of the Liouvillian recursion method to compute many-body Green's functions using a quantum computer. From an approximate ground…
Minimal-Dissipation Learning for Energy-Based Models
Jeff Hnybida, Simon Verret
We show that the bias of the approximate maximum-likelihood estimation (MLE) objective of a persistent chain energy-based model (EBM) is precisely equal to the thermodynamic excess…
Prediction of Large Magnetic Moment Materials With Graph Neural Networks and Random Forests
Sékou-Oumar Kaba, Benjamin Groleau-Paré, Marc-Antoine Gauthier +3
Magnetic materials are crucial components of many technologies that could drive the ecological transition, including electric motors, wind turbine generators and magnetic refrigera…
Seebeck coefficient in a cuprate superconductor: particle-hole asymmetry in the strange metal phase and Fermi surface transformation in the pseudogap phase
A. Gourgout, G. Grissonnanche, F. Laliberté +8
We report measurements of the Seebeck effect in both the plane () and along the axis () of the cuprate superconductor LaNdSrC…
Linear-in temperature resistivity from an isotropic Planckian scattering rate
G. Grissonnanche, Y. Fang, A. Legros +8
A variety of "strange metals" exhibit resistivity that decreases linearly with temperature as , in contrast with conventional metals where resistivity decreases as…
Fermi surface transformation at the pseudogap critical point of a cuprate superconductor
Yawen Fang, Gael Grissonnanche, Anaelle Legros +11
The nature of the pseudogap phase remains a major barrier to our understanding of cuprate high-temperature superconductivity. Whether or not this metallic phase is defined by any o…
Intrinsic Cluster-Shaped Density Waves in Cellular Dynamical Mean-Field Theory
S. Verret, J. Roy, A. Foley +3
It is well known that cellular dynamical mean-field theory (CDMFT) leads to the artificial breaking of translation invariance. In spite of this, it is one of the most successful me…
Coexistence of Superconductivity and Antiferromagnetism in the Hubbard model for cuprates
A. Foley, S. Verret, A. -M. S. Tremblay +1
Antiferromagnetism and -wave superconductivity are the most important competing ground-state phases of cuprate superconductors. Using cellular dynamical mean-field theory (CDMFT…
Thermodynamic signatures of quantum criticality in cuprates
B. Michon, C. Girod, S. Badoux +14
The three central phenomena of cuprate superconductors are linked by a common doping , where the enigmatic pseudogap phase ends, around which the superconducting phase f…
Hall effect in cuprates with incommensurate spin-density wave
M. Charlebois, S. Verret, A. Foley +3
The presence of incommensurate spiral spin-density waves (SDW) has been proposed to explain the (hole doping) to jump measured in the Hall number at a doping .…
Phenomenological theories of the low-temperature pseudogap: Hall number, specific heat and Seebeck coefficient
S. Verret, O. Simard, M. Charlebois +2
Since its experimental discovery, many phenomenological theories successfully reproduced the rapid rise from to found in the Hall number at the critical doping $p^*…
