Domain wall problem in the quantum XXZ chain and semiclassical behavior close to the isotropic point

Autor: Grégoire Misguich, Nicolas Pavloff, Vincent Pasquier

Publikováno v: SciPost Physics, Vol 7, Iss 2, p 025 (2019)

We study the dynamics of a spin-1/2 XXZ chain which is initially prepared in a domain-wall state. We compare the results of time-dependent Density Matrix Renormalization Group simulations with those of an effective description in terms of a classi

A solvable model for graph state decoherence dynamics

Autor: Jérôme Houdayer, Haggai Landa, Grégoire Misguich

Publikováno v: SciPost Physics Core, Vol 7, Iss 1, p 009 (2024)

We present an exactly solvable toy model for the continuous dissipative dynamics of permutation-invariant graph states of $N$ qubits. Such states are locally equivalent to an $N$-qubit Greenberger-Horne-Zeilinger (GHZ) state, a fundamental resource i

Nonlocal correlations in noisy multiqubit systems simulated using matrix product operators

Autor: Haggai Landa, Grégoire Misguich

Publikováno v: SciPost Physics Core, Vol 6, Iss 2, p 037 (2023)

We introduce an open-source solver for the Lindblad master equation, based on matrix product states and matrix product operators. Using this solver we study the dynamics of tens of interacting qubits with different connectivities, focusing on a probl

Generalized hydrodynamics in complete box-ball system for $U_q(\widehat{sl}_n)$

Autor: Atsuo Kuniba, Grégoire Misguich, Vincent Pasquier

Publikováno v: SciPost Physics, Vol 10, Iss 4, p 095 (2021)

We introduce the complete box-ball system (cBBS), which is an integrable cellular automaton on 1D lattice associated with the quantum group $U_q(\widehat{sl}_n)$. Compared with the conventional $(n-1)$-color BBS, it enjoys a remarkable simplificat

Bubble phase at ν= 13 for spinless hollow-core interaction

Autor: Thierry Jolicoeur, Takahiro Mizusaki, Grégoire Misguich

Publikováno v: Physical Review B. 102

We investigate fractional quantum Hall states for model interactions restricted to a repulsive hard core. When the hard core excludes relative angular momentum $m=1$ between spinless electrons the ground state at Landau level filling factor $\ensurem

Generalized hydrodynamics in box-ball system

Autor: Vincent Pasquier, Atsuo Kuniba, Grégoire Misguich

Publikováno v: J.Phys.A
J.Phys.A, 2020, 53 (40), pp.404001. ⟨10.1088/1751-8121/abadb9⟩

Box-ball system (BBS) is a prominent example of integrable cellular automata in one dimension connected to quantum groups, Bethe ansatz, ultradiscretization, tropical geometry and so forth. In this paper we study the generalized Gibbs ensemble of BBS

Multistability of Driven-Dissipative Quantum Spins

Autor: Grégoire Misguich, H. Landa, Marco Schiró

Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2020, 124 (4), ⟨10.1103/PhysRevLett.124.043601⟩

We study the dynamics of lattice models of quantum spins one-half, driven by a coherent drive and subject to dissipation. Generically the mean-field limit of these models manifests multistable parameter regions of coexisting steady states with differ

Correlation-induced steady states and limit cycles in driven dissipative quantum systems

Autor: Grégoire Misguich, Marco Schiró, H. Landa

Publikováno v: Physical Review B
Physical Review B, American Physical Society, 2020, 102 (6), ⟨10.1103/PhysRevB.102.064301⟩

We study a driven-dissipative model of spins one-half (qubits) on a lattice with nearest-neighbor interactions. Focusing on the role of spatially extended spin-spin correlations in determining the phases of the system, we characterize the spatial str

International audience; Using time-dependent density matrix renormalization group calculations we study the transport properties (I-V curves and shot noise) of the interacting resonant level model (IRLM) in a large range of the interaction parameter
