Emergent low-energy thermodynamics and universal scaling in -RuCl
A. Khansili, B. J. Ramshaw, A. Bangura +6
Quantum spin liquids are exotic states of matter in which strongly interacting spins remain disordered down to zero temperature and host fractionalized excitations. This has motiva…
Magnetic-Field-Driven Dimensional Reduction in a Quantum Antiferromagnet
Subhankar Khatua, Marcin Raczkowski, Jeroen van den Brink +1
Low dimensionality enhances quantum fluctuations, triggering novel states of quantum matter to emerge. In real materials, low dimensionality usually arises from spatially strongly…
Thermalization Dynamics in the Two-Dimensional Hubbard Model with Neural-Network Quantum States
Alessandro Sinibaldi, Luciano Loris Viteritti, Riccardo Rende +2
Thermalization in strongly correlated fermionic systems remains a central open problem in quantum many-body physics. In this work, we investigate the real-time dynamics and the app…
Observation of an emergent energy scale close to dimensional reduction in a quasi-two-dimensional quantum magnet
Anneke Reinold, Laur Peedu, Kirill Amelin +19
By appropriately perturbing a critical transverse-field Ising chain away from its critical point, the system can develop a finite correlation length with a characteristic purely ma…
Probing metal-insulator criticality with cavity photons
João C. Inácio, Natanael C. Costa, Fakher F. Assaad
The Hubbard model on the honeycomb lattice is a pristine realisation of a semimetal-to-insulator Mott transition belonging to the O(3) Gross-Neveu universality class. We couple thi…
Strain-Tuned Incommensurate Kekulé Spiral Order in Twisted Bilayer Graphene: A Quantum Many-Body Study
Cheng Huang, Yves H. Kwan, Maksim Ulybyshev +3
The physics of twisted bilayer graphene away from the exactly solvable chiral limit and the quantum Monte Carlo sign-problem-free charge neutrality point is elusive due to the expo…
Numerical evidence of a critical point in the (2+1)D SO(5) nonlinear sigma model with Wess-Zumino-Witten term
Yuan Da Liao, Bin-Bin Chen, Junchen Rong +3
We develop an optimized continuous-field quantum Monte Carlo (QMC) algorithm to investigate the projected SO(5) nonlinear sigma model with a Wess-Zumino-Witten term, which describe…
Analytic continuation of Green's functions with a neural network
Fakher Assaad, Johanna Erdmenger, Anika Götz +3
An important problem in many-body physics is to reconstruct the spectral density from the imaginary-time domain Green's function. Typically, the imaginary-time Green's function is…
Two-site entanglement in the two-dimensional Hubbard model
Frederic Bippus, Anna Kauch, Gergő Roósz +3
The study of entanglement in strongly correlated electron systems typically requires knowledge of the reduced density matrix. Here, we apply the parquet dynamical vertex approximat…
Angle-Tuned Gross-Neveu Quantum Criticality in Twisted Bilayer Graphene: A Quantum Monte Carlo Study
Cheng Huang, Nikolaos Parthenios, Maksim Ulybyshev +4
The fascinating quantum many-body states in twisted bilayber graphene (TBG) at magic angle, due to the interplay of Coulomb interactions and the quantum metrics of flat bands, have…
Hydrodynamics of particle-hole symmetric systems: a quantum Monte Carlo study
Adrien Reingruber, Kitinan Pongsangangan, Fakher Assaad +1
The emergence of hydrodynamic behavior in electronic flow within clean, particle-hole-symmetric systems at half-filling is a non-trivial problem. Navier-Stokes (NS) equations descr…
Engineering many-body quantum Hamiltonians with non-ergodic properties using quantum Monte Carlo
Nyayabanta Swain, Ho-Kin Tang, Darryl Chuan Wei Foo +5
We present a computational framework to identify Hamiltonians of interacting quantum many-body systems that host non-ergodic excited states. We combine quantum Monte Carlo simulati…
Response to Comment on "The role of electron-electron interactions in two-dimensional Dirac fermions"
Ho-Kin Tang, J. N. Leaw, J. N. B. Rodrigues +4
Hesselmann {\it et al}.~question one of our conclusions, namely, the suppression of Fermi velocity at the Gross-Neveu critical point for the specific case of vanishing long-range i…
