This paper proposes a switchable heavy-hole/light-hole spin qubit in a bilayer Ge heterostructure that combines the fast single-qubit rotations of light-hole states with the superior coherence times of heavy-hole states, achieving Rabi frequencies around 100 MHz and coherence times exceeding 100 s.
This paper presents simple, exact formulas for constructing Hamiltonians and divergence-free effective models for Josephson-junction-based superconducting qudits coupled to arbitrary passive linear environments, thereby extending blackbox quantization to multiport, dissipative, and nonreciprocal settings while eliminating spurious Lamb-shift divergences.
This study demonstrates that electrical currents can be used to selectively and directionally manipulate oxygen stoichiometry in specific branches of a multiterminal YBaCuO device, enabling post-fabrication local tuning of superconducting properties through controlled oxygen vacancy migration.
This paper demonstrates that in chiral active matter, nonequilibrium noise can induce topological bands with nonzero Chern numbers in the displacement fluctuation spectrum, creating boundary-localized modes distinct from deterministic mechanical edge states despite trivial underlying mechanics.
This paper identifies that naturally occurring quantum emitters in gallium nitride are confined near the substrate interface, limiting their optical coupling, and demonstrates that inserting a thin low-temperature GaN interlayer enables the precise, sub-60 nm depth control of bright, room-temperature quantum emitters, thereby overcoming integration barriers for efficient cavity-enhanced quantum emission.
This paper derives exact analytical expressions for the spectrum, eigenstates, and full quantum geometric tensor of the quarter-flux Harper-Hofstadter model by exploiting its sublattice symmetry, thereby demonstrating that its lowest band constitutes a nearly ideal Chern band suitable for fractional Chern insulator physics.
This paper predicts a new viscochiral transport regime in valley-polarized bilayer graphene where spatial gradients of Hall viscosity selectively amplify or suppress hydrodynamic vortices, enabling chiral flow control independent of device geometry.
This paper theoretically demonstrates that rhombohedral graphene hosts two distinct classes of multicomponent magnetic domain walls, whose specific texture is governed by the competition between intervalley Hund's coupling and spin-orbit coupling, and reveals that the dynamics of these walls can couple to superconducting transport to generate a voltage.
This paper investigates the linear and nonlinear magneto-optical transport in tilted type-I multi-Weyl semimetals using a semiclassical Boltzmann framework, deriving analytical expressions that reveal how orbital magnetic moment corrections generally suppress Berry curvature-induced conductivity while offering distinct experimental signatures of the materials' anisotropic dispersion and higher monopole charges.
This theoretical study proposes and analyzes novel van der Waals heterostructures combining Xenes with TMDCs, phosphorene, or TMTCs separated by hBN layers, demonstrating that their Rydberg indirect excitonic properties can be effectively tuned via external electric and magnetic fields, dielectric screening, and Floquet engineering to facilitate advanced optoelectronic and quantum device design.
