The development of high-speed strobe-flash photography in the 1960s by the late MIT professor Harold “Doc” Edgerton allowed us to visualize events too fast for the eye — a bullet piercing an apple, or...
In 1934, physicist Eugene Wigner made a theoretical prediction based on quantum mechanics that for decades years went unseen.
‘Spooky’ Sightings in Crystal Point to Extremely Rare Quantum Spin Liquid
Spooky Sightings Crystal Point Quantum Spin Liquid
2016/12/13
Inside a new exotic crystal, physicist Martin Mourigal has observed strong indications of “spooky” action, and lots of it. The results of his experiments, if corroborated over time, would mean th...

The use of optical lattices plays a versatile role in advancing knowledge of correlated quantum
matter. The recent orbital lattice experimentsof Wirth et al [1{3] open up a new thrust towards
discov...
Dynamic Stimulation of Quantum Coherence in Lattice Bosons
Dynamic Stimulation Quantum Coherence in Lattice Bosons

Thermal fluctuations tend to destroy long-range phase correlations. Consequently, bosons in a lattice will undergo a transition from a phase-coherent superfluid as the temperature rises. Contrary to c...

In his Comment [see preceding Comment, Phys. Rev. A 82, 037601 (2010)] on the paper by Roux [Phys.Rev. A 79, 021608(R) (2009)], Rigol argued that the energy distribution after a quench is not related ...
Valence-bond crystal in the extended Kagomé spin-1/2 quantum Heisenberg antiferromagnet: A variational Monte Carlo approach
Valence-bond crystal extended Kagomé spin-1/2 quantum variational Monte Carlo approach

The highly-frustrated spin-1=2 quantum Heisenberg model with both nearest (J1) and next-
nearest (J2) neighbor exchange interactions is revisited by using an extended variational space
of projected ...

Two-dimensional crystals of trapped ions are a promising system with which to implement quantum
simulations of challenging problems such as spin frustration. Here, we present a design for a
