Lamb-Dicke Dynamics of Interacting Rydberg Atoms Coupled to the Motion of an Optical Tweezer Array
Aslam Parvej, Ludwig Mathey
Neutral Rydberg atoms trapped in optical tweezer arrays provide a platform for quantum simulation and computation. In this work, we investigate the Lamb-Dicke dynamics of coupled R…
Optimal recoil-free state preparation in an optical atom tweezer
Lia Kley, Nicolas Heimann, Aslam Parvej +2
Quantum computing in atom tweezers requires high-fidelity implementations of quantum operations. Here, we demonstrate the optimal implementation of the transition $|0\rangle \right…
Gapless and Massive 1D Singlet Dispersion Channel in Infinite Spin-1/2 Ladders ---Infinite Quasi-1D Entanglement Perturbation Theory for Excitation
Lihua Wang, Aslam Parvej, D. ChangMo Yang +1
We solve for the elementary excitation in infinite quasi-1D quantum lattices by extending the recently developed infinite quasi-1D entanglement perturbation theory. The wave functi…
Multipolar phase in frustrated spin-1/2 and 1 chains
Aslam Parvej, Manoranjan Kumar
The spin chain model with nearest neighbor and next nearest neighbor anti-ferromagnetic interaction is one of the most popular frustrated magnetic models. Thi…
Density matrix renormalization group (DMRG) for cyclic and centrosymmetric linear chains
Manoranjan Kumar, Dayasindhu Dey, Aslam Parvej +2
The density matrix renormalization group (DMRG) method generates the low-energy states of linear systems of sites with a few degrees of freedom at each site by starting with a…
Numerical study of incommensurate and decoupled phases of spin-1/2 chains with isotropic exchange J1, J2 between first and second neighbors
Zoltán G. Soos, Aslam Parvej, Manoranjan Kumar
The spin-1/2 chain with isotropic exchange J1, J2 > 0 between first and second neighbors is frustrated for either sign of J1 and has a singlet ground state (GS) for J1/J2 …
Efficient Density Matrix Renormalization Group algorithm to study Y-Junctions with integer and half-integer spin
Manoranjan Kumar, Aslam Parvej, Simil Thomas +2
An efficient density matrix renormalization group (DMRG) algorithm is presented and applied to Y-junctions, systems with three arms of sites that meet at a central site. The ac…
Level crossing, spin structure factor and quantum phases of the frustrated spin-1/2 chain with first and second neighbor exchange
Manoranjan Kumar, Aslam Parvej, Zoltán G. Soos
The spin-1/2 chain with isotropic Heisenberg exchange , between first and second neighbors is frustrated for either sign of J1. Its quantum phase diagram has critica…
Magnetic Field Induced Exotic Phases in Isotropic Frustrated Spin-1/2 chain
Aslam Parvej, Manoranjan Kumar
The frustrated isotropic model with ferromagnetic and anti-ferromagnetic interactions in presence of an axial magnetic field shows many exotic phases, such as…
Spin structure factor and quantum phases of frustrated spin-1/2 chains
Manoranjan Kumar, Aslam Parvej, Z. G. Soos
The static structure factor S(q) of frustrated spin-1/2 chains with isotropic exchange and a singlet ground state (GS) diverges at wave vector q_m when the GS has quasi-long-range…
