Finite-Element Matrix Product States for Continuum Models in One Dimension
Akshay Shankar, Karel Van Acoleyen, Jutho Haegeman
We present a matrix product state framework for simulating one-dimensional quantum many-body systems in the continuum using non-orthogonal single-particle basis sets. By mapping th…
Fast projections of two-dimensional light patterns using acousto-optical deflectors
Robbert Decruyenaere, Clara Tanghe, Senne Van Wellen +1
Precise and flexible control of structured light fields is essential for applications ranging from optical trapping and quantum simulation to microscopy and materials processing. A…
Direct energy dissipation measurements for a driven superfluid via the harmonic-potential theorem
Clara Tanghe, Senne Van Wellen, Kobe Vergaerde +1
We propose and experimentally demonstrate a method to directly measure energy dissipation for a linearly driven superfluid confined in a harmonic trap. The method relies on a pertu…
Real-time bubble nucleation and growth for false vacuum decay on the lattice
Daan Maertens, Jutho Haegeman, Karel Van Acoleyen
We revisit quantum false vacuum decay for the one-dimensional Ising model, focusing on the real-time nucleation and growth of true vacuum bubbles. Via matrix product state simulati…
