Onset of scrambling as a dynamical transition in tunable-range quantum circuits
Sridevi Kuriyattil, Tomohiro Hashizume, Gregory Bentsen +1
In a fast scrambling many-body quantum system, information is spread and entanglement is built up on a timescale that grows logarithmically with the system size. This is of fundame…
Tunable Geometries in Sparse Clifford Circuits
Tomohiro Hashizume, Sridevi Kuriyattil, Andrew J. Daley +1
We investigate the emergence of different effective geometries in stochastic Clifford circuits with sparse coupling. By changing the probability distribution for choosing two-site…
Ground-state phase diagram of quantum link electrodynamics in -d
Tomohiro Hashizume, Jad C. Halimeh, Philipp Hauke +1
The exploration of phase diagrams of strongly interacting gauge theories coupled to matter in lower dimensions promises the identification of exotic phases and possible new univers…
Measurement-induced phase transitions in sparse nonlocal scramblers
Tomohiro Hashizume, Gregory Bentsen, Andrew J. Daley
Measurement-induced phase transitions arise due to a competition between the scrambling of quantum information in a many-body system and local measurements. In this work we investi…
Deterministic Fast Scrambling with Neutral Atom Arrays
Tomohiro Hashizume, Gregory Bentsen, Sebastian Weber +1
Fast scramblers are dynamical quantum systems that produce many-body entanglement on a timescale that grows logarithmically with the system size . We propose and investigate a f…
Numerical Probe of Dynamical Properties of a Two-Dimensional Triangular Ising Lattice with Long-Range Interaction
Tomohiro Hashizume
Motivated by the experimental realisation of the two-dimensional triangular spin lattice at the National Instate of Standards and Technology in 2012, we developed a new algorithm w…
Hybrid infinite time-evolving block decimation algorithm for long-range multi-dimensional quantum many-body systems
Tomohiro Hashizume, Jad C. Halimeh, Ian P. McCulloch
In recent years, the infinite time-evolution block decimation (iTEBD) method has been demonstrated to be one of the most efficient and powerful numerical schemes for time-evolution…
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…
Dynamical phase transitions in the two-dimensional transverse-field Ising model
Tomohiro Hashizume, Ian P. McCulloch, Jad C. Halimeh
We investigate two separate notions of dynamical phase transitions in the two-dimensional nearest-neighbor transverse-field Ising model on a square lattice using matrix product sta…
