Topological BPS charges in 10- and 11-dimensional supergravity [PDF]

open access: yes, 2010
In this thesis we construct closed expressions that correspond to the topological charges of the various BPS branes of the IIA, IIB and $D=11$ supergravity theories. These expressions are related to the structure of the SUSY algebras in curved spacetimes.

Unified Analytical Framework for Understanding the Operational Stability of Blue Phosphorescent OLEDs: Quantitative Insights Into Exciton Recycling and Bimolecular Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.

Aspects of hydrodynamics in AdS/CMT [PDF]

open access: yes, 2013
Condensed matter theory is the study of systems at finite density. In this thesis we will attempt to argue that gauge-gravity dualities can give deep and meaningful insights into the behaviour of strongly coupled condensed matter systems. The first three

Dye‐Initiated Chirped Cholesteric Polymer Networks Exhibiting Broadband Dissipative Chiral Photonic Bands

open access: yesAdvanced Functional Materials, EarlyView.
A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.

Gauge Mediated Supersymmetry Breaking in Five Dimensions

open access: yes, 2011
PhDIn this thesis we focus on the construction of models in which a supersymmetry breaking hidden sector is located on one fixed point of an extra dimensional interval and the effects are gauge mediated across this interval to the other fixed point ...

Z(_N)-symmetric field theories and the thermodynamic Bethe ansatz [PDF]

open access: yes, 1996
This thesis is concerned with perturbed conformal field theory, the thermodynamic Bethe ansatz technique and applications to statistical mechanics. In particular, the phase space of two dimensional Z(_N)-symmetric statistical models is examined using ...

Vorticity‐Driven µ‐Platelet Rotation and Selective Packing for Vertical Thermal–Electrical Interconnects

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.

A note on non-Lorentzian duality symmetries

open access: yesJournal of High Energy Physics
We work out non-Lorentzian dual actions for electromagnetism and linearised gravity, both in the Carrollian and Galilean cases. This is done in the same way as for Lorentzian theories, by first constructing a parent action that reduces to a pair of dual ...

Chronogroup via Quantum Field Theory F: Algebraic-Topological Unification in Gauge Theory and Holographic Duality

open access: yes
 Abstract This paper proposes an algebra-topology unified framework based on Chronogroup to address non-perturbative challenges in gauge theory and quantum gravity. By constructing the time-varying group law (∗t) and spectral temporal cohomology (Hk t(G,E)), we prove: 1.

Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage

open access: yesAdvanced Functional Materials, EarlyView.
Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...
