This paper presents a phenomenological resistively-shunted junction model demonstrating that bias-dependent peaks in differential resistance can suppress odd-numbered Shapiro steps in conventional Josephson junctions, offering an alternative explanation for this phenomenon often attributed to Majorana zero modes.
This study utilizes density functional theory with various exchange-correlation functionals to investigate the thermal and mechanical properties of alkali halides and hydrides, revealing that the choice of functional significantly influences predictions of lattice thermal conductivity and the conditions for observing phonon hydrodynamics, while also identifying new materials exhibiting this phenomenon.
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.
Using the numerical renormalization group method, this study demonstrates that correlated hopping induces asymmetric spin-dependent transport and significantly alters the thermoelectric efficiency of a quantum dot coupled to ferromagnetic leads by modifying Kondo resonance and conductance peak asymmetry.
This paper proposes a mechanism for electrical uni-directional molecular motors driven by electron current through helical orbitals, introduces a formal definition of helicality to link electronic angular momentum with rotational direction, and predicts that approximate sub-lattice symmetry causes the motor's sense of rotation to remain independent of the current direction.
