Katia Gallo

Katia Gallo's research interests include nanotechnology and integrated nonlinear photonic devices with a focus on optical fibre telecom and quantum optics applications, as well as more fundamental studies on the interplay of optical, electric and mechanical properties in ferroelectric materials at the nanoscale. Our activity spans theory, technology and experiments on nonlinear interactions in structured ferroelectrics, photonic crystals and integrated all-optical devices for frequency conversion, modulation and switching in classical and quantum regimes.

Val Zwiller

Val Zwiller's research combines quantum optics and nanoscience. New schemes and devices to generate, manipulate and detect quantum states of light are developed based on semiconducting, metallic and superconducting nanostructures. Light detection with superconducting nanowires gives access to unprecedented time resolutions, detection efficiencies and noise levels. Light generation with nanostructures allows for entangled states to be produced with high efficiency and fidelity while hybrid systems enable us to store and interface quantum states. Our group studies optical quantum materials from both a fundamental and a technological perspective.

His group research is focused on novel superconducting states, ultracold atomic gases, critical phenomena, multicomponent gauge theories, physical realizations of qubits, topological excitation and solitons. Egor Babaev is the recipient of US NSF CAREER Award, Outstanding Young Research award from Swedish Research Council, Outstanding Referee Award from the American Physical Society, Senior Research fellowship from the Royal Swedish Academy of Sciences, Tage Erlander prize from Royal Swedish Academy of Sciences and Goran Gustafsson prize from the Royal Swedish Academy of Sciences.

Oscar Tjernberg

Oscar’s interest is in diverse topics such as Superconductivity, topological insulators, heavy Fermion systems, metal-insulator systems, low dimensional systems etc. His main current focus is on high temperature superconductivity in cuprates and pnictides, topological insulators and the development of relevant experimental techniques such as laser based ARPES (The BALTAZAR facility) and spin-filter detectors for electron spin detection.

Alexander Balatsky

Alexander Balatsky’s research is focused on novel properties of correlated materials. One of the more exciting recent developments: discovery of graphene and topological insulators prompted him to introduce Dirac Materials as a class of materials whose properties are controlled by Dirac nodes in the excitation spectrum.
