Extrinsic quantum geometry in the quadrupolar bulk photovoltaic effect
Steven Gassner, Swati Chaudhary, Martin Claassen
The bulk photovoltaic effect has become a valuable probe of the quantum geometry of Bloch bands. While it is restricted to inversion-broken systems within the dipole approximation,…
Flux attachment theory of fractional excitonic insulators
Steven Gassner, Ady Stern, C. L. Kane
The search for fractional quantized Hall phases in the absence of a magnetic field has primarily targeted flat-band systems that mimic the features of a Landau level. In an alterna…
Floquet-Bloch Theory for Nonperturbative Response to a Static Drive
Christophe De Beule, Steven Gassner, Spenser Talkington +1
We develop the Floquet-Bloch theory of noninteracting fermions on a periodic lattice in the presence of a constant electric field. As long as the field lies along a reciprocal latt…
Light-induced switching between singlet and triplet superconducting states
Steven Gassner, Clara S. Weber, Martin Claassen
While the search for topological triplet-pairing superconductivity has remained a challenge, recent developments in optically stabilizing metastable superconducting states suggest…
Regularized lattice theory for spatially dispersive nonlinear optical conductivities
Steven Gassner, Eugene J. Mele
Nonlinear optical responses are becoming increasingly relevant for characterizing the symmetries and quantum geometry of electronic phases in materials. Here, we develop an expande…
Information Geometric Aspects of Probability Paths with Minimum Entropy Production for Quantum State Evolution
Steven Gassner, Carlo Cafaro, Sean A. Ali +1
We present an information geometric analysis of both entropic speeds and entropy production rates arising from geodesic evolution on manifolds parametrized by pure quantum states.…
Information Geometric Perspective on Off-Resonance Effects in Driven Two-Level Quantum Systems
Carlo Cafaro, Steven Gassner, Paul M. Alsing
We present an information geometric analysis of off-resonance effects on classes of exactly solvable generalized semi-classical Rabi systems. Specifically, we consider population t…
Transition Probabilities in Generalized Quantum Search Hamiltonian Evolutions
Steven Gassner, Carlo Cafaro, Salvatore Capozziello
A relevant problem in quantum computing concerns how fast a source state can be driven into a target state according to Schrödinger's quantum mechanical evolution specified by a su…
Information Geometric Complexity of Entropic Motion on Curved Statistical Manifolds under Different Metrizations of Probability Spaces
Steven Gassner, Carlo Cafaro
We investigate the effect of different metrizations of probability spaces on the information geometric complexity of entropic motion on curved statistical manifolds. Specifically,…
An information geometric perspective on the complexity of macroscopic predictions arising from incomplete information
Sean Alan Ali, Carlo Cafaro, Steven Gassner +1
Motivated by the presence of deep connections among dynamical equations, experimental data, physical systems, and statistical modeling, we report on a series of findings uncovered…
