Learning Feynman Diagrams with Tensor Trains
Yuriel Nunez-Fernandez, Matthieu Jeannin, Philipp T. Dumitrescu +4
We use tensor network techniques to obtain high order perturbative diagrammatic expansions for the quantum many-body problem at very high precision. The approach is based on a tens…
Tkwant: a software package for time-dependent quantum transport
Thomas Kloss, Joseph Weston, Benoit Gaury +3
Tkwant is a Python package for the simulation of quantum nanoelectronics devices to which external time-dependent perturbations are applied. Tkwant is an extension of the Kwant pac…
Role of the quasi-particles in an electric circuit with Josephson junctions
Benoit Rossignol, Thomas Kloss, Xavier Waintal
While Josephson junctions can be viewed as highly non-linear impedances for superconducting quantum technologies, they also possess internal dynamics that may strongly affect their…
Toward flying qubit spectroscopy
Benoit Rossignol, Thomas Kloss, Pacome Armagnat +1
While the coherent control of two level quantum systems ---qubits--- is now standard, their continuum electronic equivalents ---flying qubits--- are much less developed. A first st…
Unveiling the bosonic nature of an ultrashort few-electron pulse
Gregoire Roussely, Everton Arrighi, Giorgos Georgiou +10
Quantum dynamics is very sensitive to dimensionality. While two-dimensional electronic systems form Fermi liquids, one-dimensional systems -- Tomonaga-Luttinger liquids -- are desc…
Transient and Sharvin resistances of Luttinger liquids
Thomas Kloss, Joseph Weston, Xavier Waintal
Although the intrinsic conductance of an interacting one-dimensional system is renormalized by the electron-electron correlations, it has been known for some time that this renorma…
Effective SU(2) theory for the pseudogap state
X. Montiel, T. Kloss, C. Pépin
This paper exposes in a detailed manner the recent findings about the SU(2) scenario for the underdoped phase of the Cuprate superconductors. The SU(2) symmetry is formulated as a…
KPZ equation with short-range correlated noise: emergent symmetries and non-universal observables
Steven Mathey, Elisabeth Agoritsas, Thomas Kloss +2
We investigate the stationary-state fluctuations of a growing one-dimensional interface described by the KPZ dynamics with a noise featuring smooth spatial correlations of characte…
Angle Resolved Photo-Emission Spectroscopy signature of the Resonant Excitonic State
X. Montiel, T. Kloss, C. Pépin
We calculate the Angle Resolved PhotoEmission Spectroscopy (ARPES) signature of the Resonant Excitonic State (RES) that was proposed as the Pseudo-Gap state of cuprate superconduct…
Charge orders, magnetism and pairings in the cuprate superconductors
T. Kloss, X. Montiel, V. S. de Carvalho +2
We review the recent developments in the field of cuprate superconductors with the special focus on the recently observed charge order in the underdoped compounds. We introduce new…
Local particle-hole pair excitations by SU(2) symmetry fluctuations
X. Montiel, T. Kloss, C. Pépin
Understanding the pseudo-gap phase which opens in the under-doped regime of cuprate superconductors is one of the most enduring challenges of the physics of these compounds. A depl…
Strong competition between -loop-current order and -wave charge order along the diagonal direction in a two-dimensional hot spot model
Vanuildo S. de Carvalho, Thomas Kloss, Xavier Montiel +2
We study the fate of the so-called -loop-current order that breaks both time-reversal and parity symmetries in a two-dimensional hot spot model with antiferromagnetically m…
collective mode as A Raman resonance in cuprate superconductors
X. Montiel, T. Kloss, C. Pépin +3
We discuss the possible existence a spin singlet excitation with charge (-mode) originating the Raman resonance in cuprate superconductors. This -mode relates…
SU(2)-symmetry in a realistic spin-fermion model for cuprate superconductors
T. Kloss, X. Montiel, C. Pépin
We consider the Pseudo-Gap (PG) state of high- superconductors in form of a composite order parameter fluctuating between 2-charge ordering and superconducting (SC) pairi…

We address the timely issue of the presence of charge ordering at the hot-spots in the pseudo-gap phase of cuprate superconductors in the context of an emergent SU(2)-symmetry whic…

Thomas Kloss, Léonie Canet, Nicolás Wschebor
We investigate the strong-coupling regime of the stationary Kardar-Parisi-Zhang equation for interfaces growing on a substrate of dimension d=1, 2, and 3 using a nonperturbative re…
