Composite-Boson Ansatz for Fractional Quantum Hall Manifolds of Lattice Bosons at Generic Fillings
Umut Can Turhan, A. Levent Subaşı, Rifat Onur Umucalılar
Hofstadter systems provide a lattice route to fractional quantum Hall physics, but their low-energy manifolds often lack simple wave-function descriptions. Here we present a compos…
Vortex and fractional quantum Hall phases in a rotating anisotropic Bose gas
Umut Tanyeri, Ahmed Kallushi, Rıfat Onur Umucalılar +1
Realizing fractional quantum Hall (FQH) states in ultracold atomic systems remains a major goal despite numerous experimental advances in the last few decades. Recent progress in t…
Quantum nonlinear optics on the edge of a few-particle fractional quantum Hall fluid in a small lattice
Alberto Nardin, Daniele De Bernardis, Rifat Onur Umucalilar +3
We study the quantum dynamics in response to time-dependent external potentials of the edge modes of a small fractional quantum Hall fluid composed of few particles on a lattice in…
Bulk density signatures of a lattice quasihole with very few particles
R. O. Umucalilar
Motivated by the recent experimental realization of a two-particle fractional quantum Hall state of ultracold atoms in a small optical lattice [Nature 619, 495 (2023)], we propose…
Structure of the nearly-degenerate manifold of lattice quasiholes on a torus
Zeki Zeybek, Rifat Onur Umucalilar
We study the nearly-degenerate quasihole manifold of the bosonic Hofstadter-Hubbard model on a torus, known to host the lattice analog of the Laughlin state at filling fraction $ν=…
Autonomous stabilization of photonic Laughlin states through angular momentum potentials
Rifat Onur Umucalilar, Jonathan Simon, Iacopo Carusotto
We propose a method to stabilize Laughlin states of a large number of strongly interacting photons by combining a frequency-selective incoherent pump with a step-like potential in…
