Spectral tuning of Bloch Surface Wave resonances by light-controlled optical anisotropy
Nanophotonics, 2023 Fostered by the recent advancements in photonic technologies, the need for all-optical dynamic control on complex photonic elements is emerging as more and more relevant, especially in integrated photonics and metasurface-based flat-optics.

Evolution of the pairing pseudogap in the spectral function with interplane anisotropy [PDF]
Physical Review B, 1998 We study the pairing pseudogap in the spectral function as a function of interplane coupling. The analytical expressions for the self-energy in the critical regime are obtained for any degree of anisotropy.

The synergy between CMB spectral distortions and anisotropies [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Spectral distortions and anisotropies of the CMB provide independent and complementary probes to study energy injection processes in the early universe. Here we discuss the synergy between these observables, and show the promising future of spectral distortion missions to constrain both exotic and non-exotic energy injections. We show that conventional

Spectral distortion anisotropy from inflation for primordial black holes
Physical Review D, 2022 Single field inflationary models that seek to greatly enhance small scale power in order to form primordial black holes predict both a squeezed bispectrum that is enhanced by this small scale power and a potentially detectable enhancement of CMB spectral distortions.

Unlocking the synergy between CMB spectral distortions and anisotropies [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Abstract Measurements of the cosmic microwave background (CMB) spectral distortions (SDs) will open a new window on the very early universe, providing new information complementary to that gathered from CMB temperature and polarization anisotropies.
