Thermodynamic Green functions in theory of superconductivity [PDF]
A general theory of superconductivity is formulated within the thermodynamic Green function method for various types of pairing mediated by phonons, spin fluctuations, and strong Coulomb correlations in the Hubbard and t-J models.

A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Feynman diagram techniques in condensed matter physics [PDF]
"A concise introduction to Feynman diagram techniques, this book shows how they can be applied to the analysis of complex many-particle systems, and offers a review of the essential elements of quantum mechanics, solid state physics and statistical ...

We identify strong anisotropy in the upper critical field and magnetoresistance in the kagome superconductor LaRu3Si2, revealing pronounced electronic anisotropy. Uniaxial stress enhances magnetoresistance and Tc, with a positive correlation suggesting an electronic pairing mechanism.

Photo‐ and Thermally‐Induced Huge Layer Decoupling in Twisted Bilayer WSe2
A newly developed automated dark‐field tomography visualizes twist‐angle‐dependent structural relaxation and quantifies 3D structures in twisted bilayer WSe2. This approach reveals the evolution of local stacking configurations, thermally induced sub‐ångström interlayer decoupling, and light‐driven interlayer expansion on picosecond timescales ...

Aspects of Holographic Superconductivity [PDF]
In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both

Superconductivity: Heike's heritage [PDF]
A century ago, Heike Kamerlingh Onnes discovered superconductivity. And yet, despite the conventional superconductors being understood, the list of unconventional superconductors is growing — for which unconventional theories may be ...

Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Topological insulators: Dirac equation in condensed matter [PDF]
This new edition presents a unified description of these insulators from one to three dimensions based on the modified Dirac equation. It derives a series of solutions of the bound states near the boundary, and describes the current status of these ...

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.
