Precision thermodynamics of the strongly interacting Fermi gas in two dimensions
S. Ramachandran, S. Jensen, Y. Alhassid
The two-species cold atomic Fermi gas with attractive short-range interactions in two spatial dimensions undergoes a Bardeen-Cooper-Schrieffer (BCS) to a Bose-Einstein Condensate (…
Precision Thermodynamics of the Fermi polaron at strong coupling
S. Ramachandran, S. Jensen, Y. Alhassid
The Fermi polaron problem, which describes a mobile impurity that interacts with a spin-polarized Fermi sea, is a paradigmatic system in quantum many-body physics and has been chal…
Pseudogap regime of the unitary Fermi gas with lattice auxiliary-field quantum Monte Carlo in the continuum limit
S. Jensen, C. N. Gilbreth, Y. Alhassid
The unitary Fermi gas (UFG) is a strongly correlated system of two-species (spin-1/2) fermions with a short-range attractive interaction modeled by a contact interaction and has at…
Training models using forces computed by stochastic electronic structure methods
David M. Ceperley, Scott Jensen, Yubo Yang +3
Quantum Monte Carlo (QMC) can play a very important role in generating accurate data needed for constructing potential energy surfaces. We argue that QMC has advantages in terms of…
Stable solid molecular hydrogen above 900K from a machine-learned potential trained with diffusion Quantum Monte Carlo
Hongwei Niu, Yubo Yang, Scott Jensen +3
We survey the phase diagram of high-pressure molecular hydrogen with path integral molecular dynamics using a machine-learned interatomic potential trained with Quantum Monte Carlo…
Local imaging of diamagnetism in proximity coupled niobium nano-island arrays on gold thin films
Logan Bishop-Van Horn, Irene P. Zhang, Emily N. Waite +9
In this work we study the effect of engineered disorder on the local magnetic response of proximity coupled superconducting island arrays by comparing scanning Superconducting Quan…
Nontrivial maturation metastate-average state in a one-dimensional long-range Ising spin glass: above and below the upper critical range
S. Jensen, N. Read, A. P. Young
Understanding the low-temperature pure state structure of spin glasses remains an open problem in the field of statistical mechanics of disordered systems. Here we study Monte Carl…
Reducing the complexity of finite-temperature auxiliary-field quantum Monte Carlo
C. N. Gilbreth, S. Jensen, Y. Alhassid
The auxiliary-field quantum Monte Carlo (AFMC) method is a powerful and widely used technique for ground-state and finite-temperature simulations of quantum many-body systems. We i…
The contact in the unitary Fermi gas across the superfluid phase transition
S. Jensen, C. N. Gilbreth, Y. Alhassid
A quantity known as the contact plays a fundamental role in quantum many-body systems with short-range interactions. The determination of the temperature dependence of the contact…
The pseudogap regime in the unitary Fermi gas
S. Jensen, C. N. Gilbreth, Y. Alhassid
We discuss the pseudogap regime in the cold atomic unitary Fermi gas, with a particular emphasis on the auxiliary-field quantum Monte Carlo (AFMC) approach. We discuss possible sig…
Pairing correlations across the superfluid phase transition in the unitary Fermi gas
S. Jensen, C. N. Gilbreth, Y. Alhassid
In the two-component Fermi gas with a contact interaction, a pseudogap regime can exist at temperatures between the superfluid critical temperature and a temperature $T^* > T…
