Quantum Mpemba Effect in Dissipative Spin Chains at Criticality
The Quantum Mpemba Effect (QME) is the quantum counterpart of the classical Mpemba effect--a counterintuitive phenomenon in which a system initially at a higher temperature relax to thermal eauilibrium faster than one at a lower temperature. In this work, we investigate the QME in one-dimensional quantum spin chains coupled to a Markovian environment. By analyzing the full relaxation dynamics governed by the Lindblad master equation, we reveal the emergence of a strong quantum Mpemba effect at …

Quantum Mpemba effect in parity-time symmetric systems
The quantum Mpemba effect (QMPE), an anomalous relaxation phenomenon, has been demonstrated in both closed and open Hermitian quantum systems. While prior studies have linked the QMPE to Liouvillian exceptional points--non-Hermitian features emerged at the Liouvillian level, it remains largely elusive whether the QMPE can occur in intrinsic non-Hermitian systems, where non-Hermiticity is inherent at the Hamiltonian level. Here, we unequivocally demonstrate the occurrence of QMPE in experimental…

Why Doesn’t the Vision Pro Have More Immersive Video? Apple Is Slow-Rolling It
Apple has slow-walked the release of immersive video, creating a conundrum for the Vision Pro. Also: The company’s AI and smart home road maps are revealed; Meta prepares to sell its display glasses for under $1,000; and blood-oxygen tracking returns to Apple devices in the US.

The quantum Mpemba effect in long-range spin systems
One of the manifestations of the quantum Mpemba effect (QME) is that a tilted ferromagnet exhibits faster restoration of the spin-rotational symmetry after a quantum quench when starting from a larger tilt angle. This phenomenon has recently been observed experimentally in an ion trap that simulates a long-range spin chain. However, the underlying mechanism of the QME in the presence of long-range interactions remains unclear. Using the time-dependent spin-wave theory, we investigate the dynami…

Observation and Modulation of the Quantum Mpemba Effect on a Superconducting Quantum Processor
In non-equilibrium quantum many-body systems, the quantum Mpemba effect (QME) emerges as a counterintuitive phenomenon: systems exhibiting greater initial symmetry breaking restore symmetry faster than those with less. While theoretical exploration of QME has surged, experimental studies on its multidimensional modulation remain limited. Here, we report the observation and control of QME using a superconducting processor featuring a unique fully connected, tunable-coupling architecture that ena…
