Correlation energy of the spin-polarized uniform electron gas at high density

Pierre-François Loos, Peter M. W. Gill

The correlation energy per electron in the high-density uniform electron gas can be written as $\Ec(r_s,ζ) = \lam_0(ζ) \ln r_s + \eps_0(ζ) + \lam_1(ζ) \,r_s \ln r_s + O(r_s)$, wher…

Ground-state properties of interacting two-component Bose gases in a hard-wall trap

Yajiang Hao, Yunbo Zhang, Xi-Wen Guan +1

We investigate ground-state properties of interacting two-component Bose gases in a hard-wall trap using both the Bethe ansatz and exact numerical diagonalization method. For equal…

Phase Transitions and Pairing Signature in Strongly Attractive Fermi Atomic Gases

X W Guan, M T Batchelor, C Lee +1

We investigate pairing and quantum phase transitions in the one-dimensional two-component Fermi atomic gas in an external field. The phase diagram, critical fields, magnetization a…

Charge Order in the Falicov-Kimball Model

P. M. R. Brydon, M. Gulacsi

We examine the spinless one-dimensional Falicov-Kimball model (FKM) below half-filling, addressing both the binary alloy and valence transition interpretations of the model. Using…

Quantum versus classical behavior in the boundary susceptibility of the ferromagnetic Heisenberg chain

J. Sirker, M. Bortz

We calculate the temperature dependence of the boundary susceptibility for the quantum ferromagnetic Heisenberg chain by a modified spin-wave theory (MSWT). We find that $χ_B…
