Since the seminal work of Anderson, localization has been recognized as a standard mechanism allowing quantum many-body systems to escape ergodicity. This idea has acquired even more prominence in the last decade as it has been argued that localizati... Read More about Exact spectral statistics in strongly localized circuits.

Schottky diodes based on Be-doped p-type AlGaAs were grown by molecular beam epitaxy (MBE) and their current-voltage (I-V) and capacitance-voltage (C-V) characteristics measured. The Schottky and Ohmic contacts are Ti/Au and Au/Ni/Au, respectively. T...

Giant Photoelasticity of Polaritons for Detection of Coherent Phonons in a Superlattice with Quantum Sensitivity. Physical Review Letters, 128(15), Article 157401. https://doi.org/10.1103/physrevlett.128.157401

The functionality of phonon-based quantum devices largely depends on the efficiency of the interaction of phonons with other excitations. For phonon frequencies above 20 GHz, generation and detection of the phonon quanta can be monitored through phot...

All-optical spin locking in alkali-metal-vapor magnetometers (2022)
Journal Article

The nonlinear Zeeman effect can induce splittings and asymmetries of magnetic-resonance lines in the geophysical magnetic-field range. We demonstrate an all-optical scheme, based on spin locking, to suppress the nonlinear Zeeman effect. This scheme a... Read More about All-optical spin locking in alkali-metal-vapor magnetometers.

Photometric Signature of Ultraharmonic Resonances in Barred Galaxies (2022)
Journal Article

Bars may induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of "dark gaps,"or regions of a galaxy where the difference between the surface brightness along the bar major axis and that...

IR/UV mixing from local similarity maps of scalar non-Hermitian field theories (2022)

We propose to "gauge"the group of similarity transformations that acts on a space of non-Hermitian scalar theories. We introduce the "similarity gauge field,"which acts as a gauge connection on the space of non-Hermitian theories characterized by (an...

Chameleon gravity is an example of a model that gives rise to interesting phenomenology on cosmological scales while simultaneously possessing a screening mechanism, allowing it to avoid solar system constraints. Such models result in non-linear fiel... Read More about Chameleon screening depends on the shape and structure of NFW halos.
