One-dimensional quantum many body systems with long-range interactions

S Maity, U Bhattacharya, A Dutta - Journal of Physics A …, 2019 - iopscience.iop.org
The presence of algebraically decaying long-range interactions may alter the critical as well
as topological behaviour of a quantum many-body systems. However, when the interaction …

Breakdown of quasilocality in long-range quantum lattice models

J Eisert, M Van Den Worm, SR Manmana, M Kastner - Physical review letters, 2013 - APS
We study the nonequilibrium dynamics of correlations in quantum lattice models in the
presence of long-range interactions decaying asymptotically as a power law. For exponents …

Equivalence and nonequivalence of ensembles: Thermodynamic, macrostate, and measure levels

H Touchette - Journal of Statistical Physics, 2015 - Springer
We present general and rigorous results showing that the microcanonical and canonical
ensembles are equivalent at all three levels of description considered in statistical …

Ensemble inequivalence in long-range quantum systems

N Defenu, D Mukamel, S Ruffo - Physical Review Letters, 2024 - APS
Ensemble inequivalence, ie, the possibility of observing different thermodynamic properties
depending on the statistical ensemble which describes the system, is one of the hallmarks of …

Diverging equilibration times in long-range quantum spin models

M Kastner - Physical review letters, 2011 - APS
The approach to equilibrium is studied for long-range quantum Ising models where the
interaction strength decays like r-α at large distances r with an exponent α not exceeding the …

Spreading of correlations and entanglement in the long-range transverse Ising chain

JT Schneider, J Despres, SJ Thomson… - Physical Review …, 2021 - APS
Whether long-range interactions allow for a form of causality in nonrelativistic quantum
models remains an open question with far-reaching implications for the propagation of …

Relaxation timescales and decay of correlations in a long-range interacting quantum simulator

M Van den Worm, BC Sawyer, JJ Bollinger… - New Journal of …, 2013 - iopscience.iop.org
