Matrix-product operator dualities in integrable lattice models
Yuan Miao, Andras Molnar, Nick G. Jones
Matrix-product operators (MPOs) appear throughout the study of integrable lattice models, notably as the transfer matrices. They can also be used as transformations to construct du…
Controlled Zeno-Induced Localization of Free Fermions in a Quasiperiodic Chain
Pinaki Singha, Nilanjan Roy, Marcin Szyniszewski +1
We investigate measurement-induced localization in a continuously monitored one-dimensional Aubry--André--Harper model, focusing on the quantum Zeno regime in which the measurement…
Coarse-graining nonequilibrium diffusions with Markov chains
Ramón Nartallo-Kaluarachchi, Renaud Lambiotte, Alain Goriely
We investigate nonequilibrium steady-state dynamics in both continuous- and discrete-state stochastic processes. Our analysis focuses on planar diffusion dynamics and their coarse-…
Dynamics of Loschmidt echoes from operator growth in noisy quantum many-body systems
Takato Yoshimura, Lucas Sá
We study the dynamics of Loschmidt echoes in noisy quantum many-body systems without conservation laws. We first show that the operator Loschmidt echo in noisy unitary dynamics is…
Emergence of a Boundary-Sensitive Phase in Hyperbolic Ising Models
Xingzhi Wang, Zohar Nussinov, Gerardo Ortiz
Physical systems defined on hyperbolic lattices may exhibit phases of matter that only emerge due to negative curvature. We focus on the case of the Ising model under open boundary…
Finite temperature single-particle Green's function in the Lieb-Liniger model
Riccardo Senese, Fabian H. L. Essler
We develop a Monte Carlo sampling algorithm to numerically evaluate the Lehmann representation for the finite temperature single-particle Green's function in the repulsive Lieb-Lin…
