Dimers, trimers, tetramers, and other multimers in a multiband Bose-Hubbard model
M. Iskin, A. Keleş
We study the bound states of identical bosons that are described by a multiband Bose-Hubbard model with generic hoppings and an attractive onsite interaction. Using a variation…
Spinor Boson Droplets Stabilized By Spin Fluctuations
T. A. Yogurt, A. Keles, M. O. Oktel
Self-trapped droplets stabilized by quantum fluctuations have been experimentally realized in dipolar gases and binary Boson mixtures. We propose spinor Bose gases as another candi…
Maximum Absolute Determinants of Upper Hessenberg Bohemian Matrices
Jonathan P. Keating, Ahmet Abdullah Keleş
A matrix is called Bohemian if its entries are sampled from a finite set of integers. We determine the maximum absolute determinant of upper Hessenberg Bohemian Matrices for which…
-wave superfluidity from repulsive interaction in Rydberg-dressed Fermi gas
Ahmet Keles, Erhai Zhao, Xiaopeng Li
Interacting Fermi gas provides an ideal model system to understand unconventional pairing and intertwined orders relevant to a large class of quantum materials. Rydberg-dressed Fer…
Scrambling dynamics and many-body chaos in a random dipolar spin model
Ahmet Keles, Erhai Zhao, W. Vincent Liu
Is there a quantum many-body system that scrambles information as fast as a black hole? The Sachev-Ye-Kitaev model can saturate the conjectured bound for chaos, but it requires ran…
Renormalization group analysis of dipolar Heisenberg model on square lattice
Ahmet Keles, Erhai Zhao
We present a detailed functional renormalization group analysis of spin-1/2 dipolar Heisenberg model on square lattice. This model is similar to the well known - model an…
