Wigner crystal phases in confined carbon nanotubes
Lorinc Sarkany, Edina Szirmai, Catalin Pascu Moca +2
We present a detailed theoretical analysis of the Wigner crystal states in confined semiconducting carbon nanotubes. We show by robust scaling arguments as well as by detailed semi…
Orbital-FFLO state in a chain of high spin ultracold atoms
E. Szirmai
Recent experiments with Yb-173 and Sr-87 isotopes provide new possibilities to study high spin two-orbital systems. Within these experiments part of the atoms are excited to a high…
Interplay between exotic superfluidity and magnetism in a chain of four-component ultracold atoms
E. Szirmai, G. Barcza, J. Sólyom +1
We investigate the spin-polarized chain of ultracold fermionic atoms with spin-3/2 described by the fermionic Hubbard model with SU(4) symmetric attractive interaction. The competi…
Competing valence bond and symmetry breaking Mott states of spin-3/2 fermions on a honeycomb lattice
D. Jakab, E. Szirmai, M. Lewenstein +1
We investigate magnetic properties of strongly interacting four component spin-3/2 ultracold fermionic atoms in the Mott insulator limit with one particle per site in an optical la…

We study the effect of the coupling between the electronic ground state of high spin alkaline-earth fermionic atoms and their metastable optically excited state, when the system is…

P. Sinkovicz, A. Zamora, E. Szirmai +2
We study spin liquid phases of spin-5/2 alkaline earth atoms on a honeycomb lattice at finite temperatures. Our analysis is based on a Gutzwiller projection variational approach re…
Emergence of Quintet Superfluidity in the Chain of Partially Polarized Spin-3/2 Ultracold Atom
G. Barcza, E. Szirmai, Ö. Legeza +1
The system of ultracold atoms with hyperfine spin might be unstable against the formation of quintet pairs if the interaction is attractive in the quintet channel. We have…

We propose an experimentally feasible setup with ultracold alkaline earth atoms to simulate the dynamics of U(1) lattice gauge theories in 2+1 dimensions with a Chern-Simons term.…
Exotic magnetic orders for high spin ultracold fermions
E. Szirmai, M. Lewenstein
We study Hubbard models for ultracold bosonic or fermionic atoms loaded into an optical lattice. The atoms carry a high spin , and interact on site via strong repulsive Van…
