Thermodynamic cost of recurrent erasure
Model
Our system is subjected to a sequence of erasing protocols in time. Each erasing cycle (see Fig. 1) involves a single resetting event composed of two switching processes: 1) An instantaneous jump from the resetting (or stiff) potential V(x)…

Origin and stability of generalized Wigner crystallinity in triangular moiré systems
Classical phase diagram and competing charge-ordered states
To develop an intuition for the GWC problem, we first construct the classical ground state phase-competition diagram (t = 0 and U → ∞) for n = 1/3 of the Hamiltonian in Eq. (

Pushing the resolution limit of coherent diffractive imaging
Computational framework for RFD-based CDIs
The proposed computational framework for RFD-based CDIs is shown in Fig. 1b–d. In such lensless geometries, the measured signal is typically a diffractogram (or a sequence of such). The measured…

Mechanistic origins of temperature scaling in the early embryonic cell cycle
Temperature scaling in the Xenopus laevis embryo
We measured the temperature dependence of the timing of several early cell cycle events in the developing Xenopus laevis embryo (Fig. 1A, B), similar to the work of Crapse and colleagues32….

Observation of nonlinear edge states in an interacting atomic trimer array
Implementation of topological trimer array
For ultracold atoms in a trimer array with three sites (a, b, c) per unit cell as depicted in Fig. 1a, the system can be described by an extended 1D SSH model47, where j is the index of unit cell, and the…

Dynamical Aharonov-Bohm cages and tight meson confinement in a $${{\mathbb{Z}}}_{2}$$ -loop gauge theory
Self assembly of Aharonov-Bohm cages at h = 0
For h = 0, the electric field term drops out of the Hamiltonian (2) and the remaining hopping and flux terms locally commute. As a result, \({({S}_{{i}_{\ell }}^{z})}^{2}\) is locally conserved,…

Hybrid quantum-classical-quantum convolutional neural networks
While QCCNNs alleviate some of the limitations of fully quantum convolutional neural networks by combining quantum feature extraction with classical layers, their performance remains restricted by the expressiveness of shallow variational…
