We report multipronged progress on the stochastic averaging approach to numerical
analytic continuation of imaginary-time correlation functions computed by quantum Monte …

A quantum spin liquid (QSL) is an exotic state of matter in which electrons' spins are
quantum entangled over long distances, but do not show magnetic order in the zero …

NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

The ground-state parameters of the two-dimensional S= 1/2 antiferromagnetic Heisenberg
model are calculated using the stochastic series expansion quantum Monte Carlo method …

Strange or bad metallic transport, defined by incompatibility with the conventional
quasiparticle picture, is a theme common to many strongly correlated materials, including …

It has been conjectured that transport in integrable one-dimensional systems is necessarily
ballistic. The large diffusive response seen experimentally in nearly ideal realizations of the …

In integrable one-dimensional quantum systems an infinite set of local conserved quantities
exists which can prevent a current from decaying completely. For cases like the spin current …

The current theoretical and experimental situations are reviewed for low-dimensional
insulating systems with a low magnetic transition temperature TM and pronounced short …

A method for analytic continuation of imaginary-time correlation functions (here obtained in
quantum Monte Carlo simulations) to real-frequency spectral functions is proposed …

Quantum entanglement is a quantum-mechanical phenomenon where the quantum state of
a many-body system with many degrees of freedom cannot be described independently of …
