This paper establishes a unified theoretical framework linking orbital and heat magnetizations to experimentally accessible excitation spectra via generalized sum rules and chiral thermoelectric probes, enabling the direct measurement of these ground-state properties through dichroic measurements in quantum-engineered platforms.
This paper reports the first experimental demonstration of electrically driven plasmon-polaritonic bistability in graphene/hexagonal-boron-nitride/graphene tunneling transistors, achieved through momentum-conserving resonant tunneling of Dirac electrons and tunable via load resistance and electrostatic gating.
This paper develops a continuum model and validates it with lattice simulations to describe the shrinking dynamics of antiskyrmions in bulk DMI systems, revealing how elliptic shapes, helicity, and rotation angles evolve through coupled equations that predict specific collapse behaviors and quadrupole-like oscillations.
This paper demonstrates a compact, self-impedance matched gyrator based on edge magnetoplasmons in a GaAs 2D gas that achieves nearly lossless, unidirectional microwave transmission from 0.2 to 2 GHz without external matching networks, offering a footprint 100 times smaller and significantly lower loss than existing commercial and plasmonic devices.
This paper demonstrates that topological frustration in graphene monolayer nanomeshes induces fully flat electronic bands at the Fermi level, leading to unique hybrid spin-wave excitations that could enable low-power, ultrafast organic spintronics operating near room temperature.
This paper presents an exact quantum solution for rotating Weyl fermions in a finite cylinder, revealing that the bulk chiral vortical effect is a magnetization current while uncovering a new, temperature-independent boundary-induced vortical pumping mechanism that transports axial charge via chiral modes dependent on the number of Weyl nodes.
This paper demonstrates that hyperspectral photoluminescence imaging effectively maps microscopic strain gradients and disorder in hBN-encapsulated monolayer MoSe and WSe by quantitatively analyzing spatial variations in excitonic features, thereby revealing optoelectronic heterogeneities that conventional optical methods often miss.
This paper establishes that the singular behavior of quantum Fisher information near topological band-touching defects follows a universal power-law scaling determined solely by the defect's codimension, thereby unifying diverse topological phase transitions into a single geometric framework independent of spatial dimensionality or specific band structures.
This paper presents a focused-ion-beam-assisted electrostatic transfer method for precisely attaching prefabricated sub-micron magnetic particles to microcantilevers, enabling the creation of custom magnetic tips with minimal fabrication damage and broad applicability for scanning probe microscopy.
This paper extends the time-evolving matrix product operator (TEMPO) method within the process tensor framework to solve bosonic quantum impurity problems with off-diagonal system-bath coupling, providing a unified and generic approach that reveals the limitations of secular approximations in sub-ohmic baths and suggests future applications in fermionic generalizations and dynamical mean field theory.
