Shape coexistence in nuclei appears to be unique in the realm of finite many-body quantum
systems. It differs from the various geometrical arrangements that sometimes occur in a …

The electronic phase diagrams of many highly correlated systems, and, in particular, the
cuprate high temperature superconductors, are complex, with many different phases …

We discuss (2+ 1)-dimensional topological superconductors with N f left-and right-moving
Majorana edge modes and a Z 2× Z 2 symmetry. In the absence of interactions, these …

Antiferromagnetism and superconductivity are both fundamental and common states of
matter. In many strongly correlated systems, including the high-T c cuprates, the heavy …

Quantum Monte Carlo (QMC) simulations involving fermions have a notorious sign problem.
Some well-known exceptions to the auxiliary field QMC algorithm rely on the factorizibility of …

Determining the electronic ground state of a one-dimensional system is crucial to
understanding the underlying physics of electronic behavior. Here, we demonstrate the …

Novel competing orders are found in spin-3/2 cold atomic systems in one-dimensional
optical traps and lattices. In particular, the quartetting phase, a four-fermion counterpart of …

Neutron-rich Sr 96, 98 isotopes have been investigated by safe Coulomb excitation of
radioactive beams at the REX-ISOLDE facility. Reduced transition probabilities and …

Polaron drift in an external electric field and the dynamics following insertion of an electron
have been simulated in a one-dimensional conjugated polymer chain. The simulations were …

We have performed inelastic neutron scattering on the near ideal spin-ladder compound La
4 Sr 10 Cu 24 O 41 as a starting point for investigating doped ladders and their tendency …
