Charge order on a triangular lattice with Mott physics and arbitrary charge density
Aleksey Alekseev, Agnieszka Cichy, Konrad Jerzy Kapcia
Triangular-lattice systems attract a lot of attention due to various frustration-induced and strongly correlated effects. Here, we focus on the charge-ordering phenomenon by means…
Phase structure of the one-dimensional lattice gauge theory with second nearest-neighbor interactions
Yeimer Zambrano, Aleksey Alekseev, Konrad J. Kapcia +2
We investigate the ground-state phase diagram of a one-dimensional lattice gauge theory (LGT) model with hard-core bosons at half-filling, extending previous studies…
Particle-Hole Asymmetry and Pinball Liquid in a Triangular-Lattice Extended Hubbard Model within Mean-Field Approximation
Aleksey Alekseev, Agnieszka Cichy, Konrad Jerzy Kapcia
Recently, triangular lattice models have received a lot of attention since they can describe a number of strongly-correlated materials that exhibit superconductivity and various ma…
Spin-polarized superconducting phase in semiconducting system with next-nearest-neighbor hopping on the honeycomb lattice
Agnieszka Cichy, Konrad J. Kapcia, Andrzej Ptok
The particles in the honeycomb lattice with on-site -wave pairing exhibit many interesting behaviors, which can be described in the framework of the Hubbard model. Among others,…
Many-body correlations in one-dimensional optical lattices with alkaline-earth(-like) atoms
Valeriia Bilokon, Elvira Bilokon, Mari Carmen Bañuls +2
We explore the rich nature of correlations in the ground state of ultracold atoms trapped in state-dependent optical lattices. In particular, we consider interacting fermionic ytte…
Connection between the semiconductor--superconductor transition and the spin-polarized superconducting phase in the honeycomb lattice
Agnieszka Cichy, Konrad Jerzy Kapcia, Andrzej Ptok
The band structure of noninteracting fermions in the honeycomb lattice exhibits the Dirac cones at the corners of the Brillouin zone. As a consequence, fermions in this lattice man…
