Using a novel ultrafast imaging technique, researchers observed the space- and time-resolved propagation of neutral collective spin-valley modes, including a fast Goldstone mode and a slow amplitude mode, in twisted WSe2 moiré superlattices, providing the first direct experimental evidence of intervalley coherent states in condensed matter systems.
This paper establishes lower bounds on tunneling rates for generic double-well systems under strong magnetic fields and deep potentials, complementing previous findings that demonstrated vanishing tunneling in specially constructed cases.
This study combines scanning tunneling microscopy and ab initio calculations to reveal that the Pt(111) surface catalyzes the thermal conversion of n-octane into benzene rings via intramolecular cyclization and into polycyclic species through a zipper-like intermolecular homocoupling mechanism at temperatures above 600 K.
By measuring the work functions of Li and Li metal nanoparticles, researchers discovered a significant isotope effect and non-trivial temperature dependence that challenge simple models and highlight lithium's nature as a quantum material where electronic and ionic degrees of freedom strongly interact.
This paper demonstrates that a completely disordered diamond-dot photonic lattice can exhibit complete delocalization and perfect transmission due to a geometrical transparency window, while also showing that extreme localization can be induced by a effective magnetic flux, thereby providing a versatile platform for controlling energy transmission in disordered systems.
This paper introduces a nonperturbative variational framework based on a state-dependent polaron transformation and second-order corrections that accurately models ground states across weak, intermediate, and ultrastrong coupling regimes for both light-matter and electron-phonon systems, achieving high precision in benchmark tests like the Dicke and Holstein models.
This theoretical study proposes a phononic ring system utilizing non-equilibrium Green's function formalism to successfully realize all seven standard thermal logic gates at the nanoscale by encoding output in phonon transmission probability through tunable junction configurations.
This paper reports the first experimental demonstration of millimeter-wide, nanoscale-thick silicon nitride photonic crystal lightsails that achieve 99% reflectivity and record-breaking radiation-pressure displacements under high-power laser intensities, establishing a viable testbed for directed-energy propulsion systems.
This paper investigates the transient suppression of on-dot electron pairing and its impact on subgap charge transport in a superconductor-quantum dot-normal metal junction when both dots are singly occupied by identical spins, providing temporal scales for these nonequilibrium triplet configurations that are relevant to superconducting qubit operations.
This paper demonstrates the phase locking of a Si nuclear spin ensemble in a silicon quantum dot using only internal electronic spin-orbit coupling as a phase reference, thereby enabling coherent control and measurement of nuclear spin dynamics without external microwave fields.
