A PhD project is available in the Nonlinear Optics group at the Institute of Applied Science – University of Bern.
Our research uses ultrashort intense lasers and terahertz pulses to probe and control the properties of complex solids. We focus on the nonequilibrium dynamics of quantum materials-including systems that exhibit macroscopic quantum phenomena (e.g., high-temperature superconductivity). By driving materials far from equilibrium and tracking their response on femtosecond timescales, we access structural, spin, and electronic dynamics and uncover the underlying out-of-equilibrium physics.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
This position addresses a foundational physics challenge at the intersection of condensed matter and quantum technology, focusing on the transient manipulation of quantum material states far from thermodynamic equilibrium. By leveraging femtosecond resolution and terahertz (THz) radiation—a critical, low-energy regime—this research provides the essential time-domain intelligence required to engineer new functionalities in quantum devices, such as the potential non-thermal control over high-temperature superconductivity (high-Tc). The strategic importance lies in shifting materials science from static observation to dynamic control, thereby informing the development of next-generation, high-performance quantum hardware components and novel electronic architectures.
This specialized domain sits squarely within the foundational research layer of the quantum technology stack, specifically targeting material innovation necessary for the commercialization of quantum computing, sensing, and advanced electronics. A primary industry bottleneck is the limited understanding and control over decoherence mechanisms and emergent quantum phenomena in solid-state systems. Current technology readiness levels (TRL) for novel quantum materials (e.g., excitonic insulators, non-equilibrium superconductors) remain low due to the challenge of isolating and manipulating the competing degrees of freedom (charge, spin, lattice) on their intrinsic ultrafast timescales. The workforce gap is acute in experimentalists proficient in both ultra-high vacuum techniques and complex time-resolved spectroscopy, particularly those utilizing high-intensity THz sources which are essential for driving non-linear material responses. The resulting data, which maps transient band structures and macroscopic phenomena, acts as crucial feedback for computational materials design pipelines, directly influencing vendor efforts in cryogenic component stability and qubit substrate selection. Success in this area de-risks future investment in solid-state quantum platforms by demonstrating engineered control over collective quantum states at femtosecond speeds.
The technical architecture underpinning this research relies on mastering complex, multi-modal ultrafast spectroscopy setups. Core capability domains include the precise generation and synchronization of intense ultrashort laser pulses and coherent terahertz radiation, demanding expertise in nonlinear optics and beamline stabilization to maintain experimental fidelity. The engineering outcome is the ability to perform time-resolved measurements that isolate specific quantum dynamics (e.g., transient changes in conductivity or spin ordering), requiring advanced data analysis techniques like global and phase-sensitive fitting of spectroscopic traces. Proficiency in large-scale facility protocols, such as synchrotrons or Free-Electron Lasers (FELs), enables the extension of probing energies into the X-ray regime, crucial for observing structural and momentum-resolved electronic transitions. This mastery of instrumentation and data interpretation ensures the generation of high-throughput, high-stability data sets required for predictive modeling of driven quantum matter. * Establishes fundamental control protocols for emergent quantum states (e.g., transient superconductivity) via non-thermal manipulation.
