Non-thermal melting of Neel order in the Hubbard model
Karsten Balzer, F. Alexander Wolf, Ian P. McCulloch +2
We study the unitary time evolution of antiferromagnetic order in the Hubbard model after a quench starting from the perfect Néel state. In this setup, which is well suited for exp…
Coupled mode theory for acoustic resonators
Dmitrii N. Maksimov, Almas F. Sadreev, Alina A. Lyapina +1
We develop the effective non-Hermitian Hamiltonian approach for open systems with Neumann boundary conditions. The approach can be used for calculating the scattering matrix and th…
Dynamical correlation functions and the quantum Rabi model
F. Alexander Wolf, Fabio Vallone, Guillermo Romero +3
We study the quantum Rabi model within the framework of the analytical solution developed in Phys. Rev. Lett. 107,100401 (2011). In particular, through time-dependent correlation f…
Exact real-time dynamics of the quantum Rabi model
F. Alexander Wolf, Marcus Kollar, Daniel Braak
We use the analytical solution of the quantum Rabi model to obtain absolutely convergent series expressions of the exact eigenstates and their scalar products with Fock states. Thi…
Expansion of Bose-Hubbard Mott insulators in optical lattices
Mark Jreissaty, Juan Carrasquilla, F. Alexander Wolf +1
We study the expansion of bosonic Mott insulators in the presence of an optical lattice after switching off a confining potential. We use the Gutzwiller mean-field approximation an…
Generalized Gibbs ensemble prediction of prethermalization plateaus and their relation to nonthermal steady states in integrable systems
Marcus Kollar, F. Alexander Wolf, Martin Eckstein
A quantum many-body system which is prepared in the ground state of an integrable Hamiltonian does not directly thermalize after a sudden small parameter quench away from integrabi…
Collapse and revival oscillations as a probe for the tunneling amplitude in an ultra-cold Bose gas
F. Alexander Wolf, Itay Hen, Marcos Rigol
We present a theoretical study of the quantum corrections to the revival time due to finite tunneling in the collapse and revival of matter wave interference after a quantum quench…
New theoretical approaches for correlated systems in nonequilibrium
M. Eckstein, A. Hackl, S. Kehrein +4
We review recent developments in the theory of interacting quantum many-particle systems that are not in equilibrium. We focus mainly on the nonequilibrium generalizations of the f…
