Union of two physics tools sheds light on quantum chaos

IQIM graduate student Nicole Yunger Halpern explores quantum chaos in her new publication Jarzynski-like equality for the out-of-time-ordered correlator What do black holes have in common with DNA? Black holes are chaotic quantum systems, which scramble information rapidly. DNA obeys fluctuation relations, equations that govern the energy needed to perform tasks like the uncoiling a [...]

Atom–atom interactions around the band edge of a photonic crystal waveguide

A new paper by the Kimble group reports initial observation of cooperative atom–atom interactions around the band edge of a photonic crystal waveguide. "In recent years, there has been considerable effort to bring ultracold atoms into the realm of nanophotonics. Nanoscopic dielectric devices offer unprecedented opportunities to engineer novel capabilities for the control of atom–photon [...]

Derivations of the thermal state of a quantum system that has noncommuting charges

Recently reignited interest in quantum thermodynamics has prompted information-theoretic approaches to fundamental questions, including the roles of entanglement, measurement, and noncommutation. A central concept in statistical mechanics is the thermal state. The thermal state of a system that exchanges heat with a bath, or heat and particles, or other commuting observables, is well-known. But quantum [...]
