Dipolar mixtures in checker-board optical bilayers
Rukmani Bai, Luis Santos
Ultra-cold dipolar mixtures in component-dependent optical potentials constitute an interesting platform for the study of the interplay between intra- and inter-component anisotrop…
Topological phase transition in anti-symmetric Lotka-Volterra doublet chain
Rukmani Bai, Sourin Chatterjee, Ujjwal Shekhar +3
We present the emergence of topological phase transition in the minimal model of two dimensional rock-paper-scissors cycle in the form of a doublet chain. The evolutionary dynamics…
Homogeneous Magnetic Flux in Rydberg Lattices
Joseph Eix, Rukmani Bai, Thierry Lahaye +3
We present a method for generating homogeneous and tunable magnetic flux for bosonic particles in a lattice using Rydberg atoms. Our setup relies on Rydberg excitations hopping thr…
Miscibility-Immiscibility transition of strongly interacting bosonic mixtures in optical lattices
Rukmani Bai, Soumik Bandyopadhyay
Interaction plays key role in the mixing properties of a multi-component system. The miscibility-immiscibility transition (MIT) in a weakly interacting mixture of Bose gases is pre…
Switching modulation of spin transport in ferromagnetic tetragonal silicene
Liehong Liao, Ying Ding, Fei Wan +6
We study the band structure and transport properties of ferromagnetic tetragonal silicene nanoribbons by using the non-equilibrium Green's function method. The band structure and s…
Field free switching through bulk spin-orbit torque in L10-FePt films deposited on vicinal substrates
Yongming Luo, Yanshan Zhuang, Zhongshu Feng +9
L10-FePt distinguishes itself for its ultrahigh perpendicular magnetic anisotropy (PMA), which enables memory cells with sufficient thermal stability to scale down to 3 nm. The rec…

Sebastian Weber, Rukmani Bai, Nastasia Makki +6
We present a setup with Rydberg atoms for the realization of a bosonic fractional Chern insulator in artificial matter. The suggested setup relies on Rydberg atoms arranged in a ho…
Quantum phases of dipolar bosons in multilayer optical lattice
Soumik Bandyopadhyay, Hrushikesh Sable, Deepak Gaur +3
We consider a minimal model to investigate the quantum phases of hardcore, polarized dipolar atoms confined in multilayer optical lattices. The model is a variant of the extended B…

Vincent Lienhard, Pascal Scholl, Sebastian Weber +8
We experimentally realize a Peierls phase in the hopping amplitude of excitations carried by Rydberg atoms, and observe the resulting characteristic chiral motion in a minimal setu…
