Kapitza Stabilization of Quantum Critical Order
Dushko Kuzmanovski et al.
Phys. Rev. X 14, 021016 (2024)Using the electric field of a laser pulse to rapidly shake the atoms in a material can stabilize a ferroelectric state, a proposal that extends the concept of “Kapitza engineering” to quantum critical points.

Quantum Jamming Brings Quantum Mechanics to Macroscopic Scales
Maurizio Fagotti
Phys. Rev. X 14, 021015 (2024)A quantum spin-1/2 chain model with kinetic constraints that trigger jamming of its quasiparticles reveals a potential way to explore quantum properties in some systems on a macroscopic scale.

Nonreciprocal Pattern Formation of Conserved Fields
Fridtjof Brauns and M. Cristina Marchetti
Phys. Rev. X 14, 021014 (2024)A minimal model describes the emergence of traveling and oscillating states, unifying a broad range of multicomponent systems where effective interactions violate Newton’s third law.

Chiral Pseudospin Liquids in Moiré Heterostructures
Clemens Kuhlenkamp, Wilhelm Kadow, Ataç Imamoğlu, and Michael Knap
Phys. Rev. X 14, 021013 (2024)Spin liquids are intrinsically difficult to prepare, observe, and characterize, but carefully designed multilayer structures in 2D materials may overcome these obstacles.
