Integrable two-channel p_x+ip_y-wave superfluid model
S. Lerma H., S. M. A. Rombouts, J. Dukelsky +1
We present a new two-channel integrable model describing a system of spinless fermions interacting through a p-wave Feshbach resonance. Unlike the BCS-BEC crossover of the s-wave c…
The competition between superconductivity and ferromagnetism in small metallic grains: thermodynamic properties
K. Van Houcke, Y. Alhassid, S. Schmidt +1
We study the thermodynamic properties of a small superconducting metallic grain using a quantum Monte Carlo method. The grain is described by the universal Hamiltonian, containing…
Quantum phase diagram of the integrable p_x+ip_y fermionic superfluid
Stefan M. A. Rombouts, Jorge Dukelsky, Gerardo Ortiz
We determine the zero temperature quantum phase diagram of a p_x+ip_y pairing model based on the exactly solvable hyperbolic Richardson-Gaudin model. We present analytical and larg…
Unconventional pairing phases in the two-dimensional attractive Hubbard model with population imbalance
Stefan M. A. Rombouts
The ground state phase diagram of the two-dimensional attractive Hubbard model with population imbalance is explored using a mean field ansatz. A linear programming algorithm is us…
Microscopic calculation of symmetry projected nuclear level densities
K. Van Houcke, S. M. A. Rombouts, K. Heyde +1
We present a quantum Monte Carlo method with exact projection on parity and angular momentum that is free of sign-problems for seniority-conserving nuclear interactions. This techn…
Survival of parity effects in superconducting grains at finite temperature
K. Van Houcke, S. M. A. Rombouts, L. Pollet
We study the thermodynamics of a small, isolated superconducting grain using a recently developed quantum Monte Carlo method. This method allows us to simulate grains at any finite…
