Altermagnetism-driven FFLO superconductivity in finite-filling 2D lattices

AAPPS Bulletin
We systematically investigate the emergence of finite-momentum Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconductivity in a square lattice Hubbard model with finite filling, driven by either $$d_{xy}$$ -wave or $$d_{x^{2}-y^{2}}$$ -wave altermagnetic ...

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

String Theory – Nomological Unification and the Epicycles of the Quantum Field Theory Paradigm [PDF]

, 2011
String Theory is the result of the conjunction of three conceptually independent elements: (i) the metaphysical idea of a nomological unity of the forces, (ii) the model-theoretical paradigm of Quantum Field Theory, and (iii) the conflict resulting from ...

Quantum theory of reactive scattering in phase space [PDF]

, 2010
We review recent results on quantum reactive scattering from a phase space perspective. The approach uses classical and quantum versions of normal form theory and the perspective of dynamical systems theory.

Quantum Lifshitz points in an altermagnetic superconductor

AAPPS Bulletin
We predict the existence of two tri-critical quantum Lifshitz points in recently discovered d-wave altermagnetic metals subjected to an external magnetic field.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Clocks, correlations and interactions in timeless quantum theory [PDF]

The notion of time as an external parameter regulating the dynamics of physical systems is unsatisfactory from an explanatory point of view. It also clashes with the background-independent character of general relativity.

Non-relativistic Quantum Mechanics [PDF]

, 2006
This essay is a discussion of the philosophical and foundational issues that arise in non-relativistic quantum theory. After introducing the formalism of the theory, I consider: characterizations of the quantum formalism, empirical content, uncertainty ...

Exact calculation of spectral properties of a particle interacting with a one-dimensional Fermi gas in optical lattices

AAPPS Bulletin
By using the exact Bethe wavefunctions of the one-dimensional Hubbard model with N spin-up fermions and one spin-down impurity, we derive an analytic expression of the impurity form factor, in the form of a determinant of a $$(N+1)$$ ( N + 1 ) by $$(N+1)$

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

Advanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.
