Controlling and measuring the temperature in different devices and platforms that operate in
the quantum regime is, without any doubt, essential for any potential application. In this …

Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

We report on the deterministic preparation of antiferromagnetic Heisenberg spin chains
consisting of up to four fermionic atoms in a one-dimensional trap. These chains are …

We show that strongly interacting multicomponent gases in one dimension realize an
effective spin chain, offering an alternative simple scenario for the study of one-dimensional …

A major challenge in modern physics is to accurately describe strongly interacting quantum
many-body systems. One-dimensional systems provide fundamental insights because they …

We present a general form of the effective spin-chain model for strongly interacting atomic
gases with an arbitrary spin in one-dimensional (1D) traps. In particular, for high-spin …

We study a one-dimensional two-component Fermi gas in a harmonic trapping potential
using finite-temperature lattice quantum Monte Carlo methods. We are able to compute …

We prove that as a one-dimensional Fermi gas is brought across the resonance
adiabatically from large repulsion to large attraction, the singlet ground state will give way to …

We present the complete phase diagram for one-dimensional binary mixtures of bosonic
ultracold atomic gases in a harmonic trap. We obtain exact results with direct numerical …

We study the dynamics of two strongly interacting bosons with an additional impurity atom
trapped in a harmonic potential. Using exact numerical diagonalization we are able to fully …
