Density-Matrix Renormalization Group for Continuous Quantum Systems
Shovan Dutta, Anton Buyskikh, Andrew J. Daley +1
We introduce a versatile and practical framework for applying matrix product state techniques to continuous quantum systems. We divide space into multiple segments and generate con…
Adiabatic preparation of entangled, magnetically ordered states with cold bosons in optical lattices
Araceli Venegas-Gomez, Johannes Schachenmayer, Anton S. Buyskikh +3
We analyze a scheme for preparation of magnetically ordered states of two-component bosonic atoms in optical lattices. We compute the dynamics during adiabatic and optimized time-d…
Dynamics of rotated spin states and magnetic ordering with two-component bosonic atoms in optical lattices
Araceli Venegas-Gomez, Anton S. Buyskikh, Johannes Schachenmayer +2
The microscopic control available over cold atoms in optical lattices has opened new opportunities to study the properties of quantum spin models. While a lot of attention is focus…
Enhanced Superexchange in a Tilted Mott Insulator
Ivana Dimitrova, Niklas Jepsen, Anton Buyskikh +4
In an optical lattice entropy and mass transport by first-order tunneling is much faster than spin transport via superexchange. Here we show that adding a constant force (tilt) sup…
Treelike interactions and fast scrambling with cold atoms
Gregory Bentsen, Tomohiro Hashizume, Anton S. Buyskikh +4
We propose an experimentally realizable quantum spin model that exhibits fast scrambling, based on non-local interactions which couple sites whose separation is a power of 2. By co…
Resonant two-site tunnelling dynamics of bosons in a tilted optical superlattice
Anton S. Buyskikh, Luca Tagliacozzo, Dirk Schuricht +3
We study the non-equilibrium dynamics of a 1D Bose-Hubbard model in a gradient potential and a superlattice, beginning from a deep Mott insulator regime with an average filling of…
Spin-models, dynamics and criticality with atoms in tilted optical superlattices
Anton S. Buyskikh, Luca Tagliacozzo, Dirk Schuricht +3
We show that atoms in tilted optical superlattices provide a platform for exploring coupled spin chains of forms that are not present in other systems. In particular, using a perio…
Efficient tomography of a quantum many-body system
B. P. Lanyon, C. Maier, M. Holzäpfel +10
Quantum state tomography (QST) is the gold standard technique for obtaining an estimate for the state of small quantum systems in the laboratory. Its application to systems with mo…
Entanglement growth and correlation spreading with variable-range interactions in spin and fermionic tunnelling models
Anton S. Buyskikh, Maurizio Fagotti, Johannes Schachenmayer +2
We investigate the dynamics following a global parameter quench for two 1D models with variable-range power-law interactions: a long-range transverse Ising model, which has recentl…
