Flux-Floquet instability in fluctuating superconductors
Marios H. Michael, Duilio De Santis, Eugene A. Demler +1
In the past decade, photo-induced superconducting-like behaviors have been reported in a number of materials driven by intense pump fields. Of particular interest is the high-Tc cu…
Probing the Berezinskii-Kosterlitz-Thouless vortex unbinding transition in two-dimensional superconductors using local noise magnetometry
Jonathan B. Curtis, Nikola Maksimovic, Nicholas R. Poniatowski +4
The melting of quasi-long-range superconductivity in two spatial dimensions occurs through the proliferation and unbinding of vortex-antivortex pairs -- a phenomenon known as the B…
Terahertz amplification and lasing in pump-probe experiments with hyperbolic polaritons in h-BN
Khachatur G. Nazaryan, Ivan Ridkokasha, Marios H. Michael +1
We discuss terahertz pump-probe experiments in hBN from the perspective of Floquet optical materials and photonic time crystals. Anisotropic nature of this material results in a la…
Itinerant magnetism and magnetic polarons in the triangular lattice Hubbard model
Ivan Morera, Eugene Demler
We use density matrix renormalization group to investigate the phase diagram of the Fermi Hubbard model on a triangular lattice with densities above half-filling, . W…
Dynamic magnetic phase transition induced by parametric magnon pumping
Jun-Yi Shan, Jonathan B. Curtis, Mingyao Guo +7
Uncovering pathways to optically drive magnetic order-disorder transitions on ultrashort timescales can lead to the realization of novel out-of-equilibrium quantum phenomena. A lon…
Principles of 2D terahertz spectroscopy of collective excitations: the case of Josephson plasmons in layered superconductors
Alex Gómez Salvador, Pavel E. Dolgirev, Marios H. Michael +5
Two-dimensional terahertz spectroscopy (2DTS), a terahertz analogue of nuclear magnetic resonance, is a new technique poised to address many open questions in complex condensed mat…
Squeezed Josephson plasmons in driven YBaCuO
N. Taherian, M. Först, A. Liu +10
The physics of driven collective modes in quantum materials underpin a number of striking non-equilibrium functional responses, which include enhanced magnetism, ferroelectricity a…
