This paper reports the observation of two-component exciton Bose-Einstein condensates in MoSe2/hBN/WSe2 electron-hole bilayers, demonstrating distinct spin-valley polarized phases and quantum phase transitions up to approximately 1.8 K through magneto-optical spectroscopy.
This study demonstrates that reducing the pulse duration in YBCO bridges from milliseconds to nanoseconds significantly increases the onset current for oxygen electromigration by lowering local temperatures, thereby shifting the process toward an athermal regime with important implications for memristor operation and thermomagnetic stability.
This paper derives a generalized Thiele equation incorporating spin-transfer torque on curved surfaces, revealing a coupling between current and curvature that induces an additional Hall effect and modifies the Walker limit for skyrmion dynamics in nanotubes.
This paper proves that while non-reciprocal electromagnetic systems in global thermal equilibrium can sustain a non-zero, divergence-free mean Poynting vector (persistent energy current), this phenomenon cannot be detected through out-of-equilibrium heat transfer measurements.
This paper maps out the analytically tractable landscape of multifold exceptional structures in three and four dimensions under generalized similarities, revealing that spectral symmetries induced by these similarities can reduce the dimensionality of exceptional point manifolds beyond naive constraint counting, thereby unifying diverse physical scenarios from optics to open quantum systems.
This paper presents a general method for computing the classification groups of topological insulators and superconductors under arbitrary point group symmetries, demonstrating that these classifications are fully determined by the number of momentum and real-space variables flipped by individual and paired symmetry generators.
This study reveals that twisted bilayer MoTe hosts an intervalley superconducting phase emerging from a non-Abelian fractional spin Hall insulator, driven by the condensation of charge- non-Abelian anyons and supported by both exact diagonalization and field-theoretic analyses.
This paper theoretically investigates the optical response of strained monolayer CrSBr, specifically analyzing how various strain configurations modify its excitonic peaks and the diagonal components of the linear conductivity tensor.
This paper demonstrates that driven-dissipative nonlinear magnetic multilayers can spontaneously form a chiral spin superfluid condensate that acts as a nonreciprocal diode and, through spatial drive modulation, generates sonic horizons to produce Hawking-like magnon emission, thereby establishing a tabletop platform for studying non-Hermitian universality and analogue gravity.
This paper presents an exact analytical solution for time-evolving resonant states in an open double quantum-dot system with spin and Coulomb interactions, deriving a non-Hermitian effective Hamiltonian that identifies four types of two-body resonant states and enables the precise calculation of survival and transition probabilities for localized electrons.
