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…
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…
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…
Fulde-Ferrell states in unequally charged Fermi gases
A. Levent Subaşı, Nader Ghazanfari
Atoms with different internal states can exhibit different responses to an artificial magnetic field. An atomic gas mixture of two different components can therefore be interpreted…
Phase separation in a mixture of trapped charged Bose-Einstein condensates
S. Seyyare Aksu, A. Levent Subaşı, Nader Ghazanfari
We study the phase separation configurations and their rotational properties for a mixture of two interacting charged Bose-Einstein condensates subject to a magnetic field trapped…
Charge and statistics of lattice quasiholes from density measurements: a Tree Tensor Network study
Elia Macaluso, Tommaso Comparin, Rifat Onur Umucalılar +4
We numerically investigate the properties of the quasihole excitations above the bosonic fractional Chern insulator state at filling , in the specific case of the Harper-Ho…
Mixture of two unequally charged superfluids in a magnetic field
S. Seyyare Aksu, A. Levent Subaşı, Nader Ghazanfari
The artificial magnetic fields engineered for ultra cold gases depend on the internal structure of the neutral atoms. Therefore the components of a mixture composed of two atomic g…
Real-space probe for lattice quasiholes
R. O. Umucalilar
We propose a real-space probe that is based on density measurements to extract distinct signatures of quasihole-like states of bosons experiencing a synthetic magnetic field in a t…
Time-of-Flight Measurements as a Possible Method to Observe Anyonic Statistics
Rifat Onur Umucalilar, Elia Macaluso, Tommaso Comparin +1
We propose a standard time-of-flight experiment as a method for observing the anyonic statistics of quasiholes in a fractional quantum Hall state of ultracold atoms. The quasihole…
Generation and spectroscopic signatures of a fractional quantum Hall liquid of photons in an incoherently pumped optical cavity
R. O. Umucalilar, I. Carusotto
We theoretically investigate a driven-dissipative model of strongly interacting photons in a nonlinear optical cavity in the presence of a synthetic magnetic field. We show the pos…
BCS theory of time-reversal-symmetric Hofstadter-Hubbard model
R. O. Umucalilar, M. Iskin
The competition between the length scales associated with the periodicity of a lattice potential and the cyclotron radius of a uniform magnetic field is known to have dramatic effe…
Acoustic superradiance from an optical-superradiance-induced vortex in a Bose-Einstein condensate
Nader Ghazanfari, Ozgur E. Mustecaplioglu
We consider the simultaneous scattering of an angular momentum carrying Laguerre-Gaussian light beam and an acoustic wave from an atomic Bose-Einstein condensate, under condition o…
