Fate of the "vacuum point'' and of grey solitons in dispersive quantum shock waves in a one-dimensional Bose gas
S. A. Simmons, J. C. Pillay, K. V. Kheruntsyan
We continue the study of dispersive quantum shock waves in a one-dimensional Bose gas beyond the mean-field approximation. In a recent work by Simmons et al. [Phys. Rev. Let. 125,…
Quantum utility -- definition and assessment of a practical quantum advantage
Nils Herrmann, Daanish Arya, Marcus W. Doherty +4
Several benchmarks have been proposed to holistically measure quantum computing performance. While some have focused on the end user's perspective (e.g., in application-oriented be…
Phase-space stochastic quantum hydrodynamics for interacting Bose gases
S. A. Simmons, J. C. Pillay, K. V. Kheruntsyan
Hydrodynamic theories offer successful approaches that are capable of simulating the otherwise difficult-to-compute dynamics of quantum many-body systems. In this work we derive, w…
What is a quantum shock wave?
S. A. Simmons, F. A. Bayocboc, J. C. Pillay +3
Shock waves are examples of the far-from-equilibrium behaviour of matter; they are ubiquitous in nature, yet the underlying microscopic mechanisms behind their formation are not we…
Cumulants and Scaling Functions of Infinite Matrix Product States
Jason C. Pillay, Ian P. McCulloch
The order parameter cumulants of infinite matrix product ground states are evaluated across a quantum phase transition. A scheme using the Binder cumulant, finite-entanglement scal…
Topological phase transition and the effect of Hubbard interaction on the one-dimensional topological Kondo insulator
Jason C. Pillay, Ian P. McCulloch
The effect of a local Kondo coupling and Hubbard interaction on the topological phase of the one-dimensional topological Kondo insulator (TKI) is numerically investigated using the…
Measurement of a topological edge invariant in a microwave network
Wenchao Hu, Jason Cornelius Pillay, Kan Wu +3
We report on the measurement of topological invariants in an electromagnetic topological insulator analog formed by a microwave network, consisting of the winding numbers of scatte…
Generalized Sub-Schawlow-Townes Laser Linewidths Via Material Dispersion
Jason Cornelius Pillay, Natsume Yuki, A. Douglas Stone +1
A recent S matrix-based theory of the quantum-limited linewidth, which is applicable to general lasers, including spatially non-uniform laser cavities operating above threshold, is…
Neel to spin-Peierls transition in a quasi-1D Heisenberg model coupled to bond phonons
Jason Cornelius Pillay, Keola Wierschem, Pinaki Sengupta
The zero and finite temperature spin-Peierls transitions in a quasi-one-dimensional spin-1/2 Heisenberg model coupled to adiabatic bond phonons is investigated using the Stochastic…
