This study characterizes the magnetic properties of an individual *Magnetospirillum gryphiswaldense* bacterium by combining ultrasensitive torque magnetometry, transmission electron microscopy, and micromagnetic simulations to reveal the magnetic configurations, remanent moment, and effective anisotropy of its internal magnetosome chain.
This paper reports the first direct observation of double-dome superconductivity in magic-angle twisted trilayer graphene, where the suppression of superconductivity near a specific filling factor reveals a distinct phase transition and supports the existence of an unconventional superconducting order parameter linked to an incommensurate Kekulé spiral state.
This paper demonstrates that broken intrinsic symmetry in a synthetic ferrimagnet induces a strong coupling between acoustic and optical magnon modes, resulting in a large avoided level-crossing gap of 3.9 GHz that is tunable via interlayer exchange interaction and exceeds typical coupling strengths in other magnonic hybrid systems.
This paper demonstrates a highly coherent singlet-triplet hole spin qubit in germanium that achieves high-fidelity universal control and a tenfold increase in coherence time via resonant driving at low magnetic fields and low exchange interaction, effectively overcoming the trade-off between gate speed and charge noise sensitivity.
This paper reformulates the Chern character in topological K-theory using Fermi points of Fredholm operators to generalize spectral flow and provide elementary proofs for the evenness of the edge index and the bulk-edge correspondence in four-dimensional time-reversal symmetric topological insulators (class AI).
This paper demonstrates that coupling chiral fermions to local, dispersionless phonons induces a topological splitting of the phonon spectrum into flat and linearly dispersing bands with hedgehog-like Berry curvature, revealing a phonon parity anomaly that enables phonon currents to directly probe electronic chirality and topological structures.
Using angle-resolved photoemission spectroscopy, researchers successfully created, detected, and controlled quasi-steady dark excitons in doped SnSe2, revealing a novel anisotropic excitonic gap phase that extends the study of dark excitons from ultrafast timescales to quasi-equilibrium conditions.
This paper derives an expression for local Hall conductivity in disordered systems to demonstrate that non-magnetic disorder and the fragmentation of disordered patches can expand the parameter regimes for both Chern insulating states and topological Anderson insulators, thereby motivating new local experimental techniques to visualize these effects.
This paper extends the concept of altermagnetism to quasicrystals by using a hyperspatial projection framework to demonstrate that interaction-induced Néel order on decorated Ammann-Beenker and Penrose lattices gives rise to unconventional -wave and -wave altermagnetic phases with momentum-dependent spin splitting compatible with noncrystallographic rotational symmetries.
This study reports the observation of electrostatic gate-controlled Altshuler-Aronov-Spivak quantum interference oscillations in a high-mobility two-dimensional electron gas at the (LaSr)(AlTa)O/SrTiO interface, attributed to closed-loop paths along SrTiO domain walls and demonstrating a long phase coherence length that highlights the potential of complex oxide interfaces for quantum technologies.
