Planckian metals have the potential to power high-temperature superconductors, quantum computers and a host of other next-generation technologies. However, these “strange” metals – in which electrical...
We investigate the design of taper structures for coupling to slow-light modes of various photonic-crystal waveguides while taking into account parameter uncertainties inherent in practical fabricatio...
The strong coupling treatment of the Fr¨ohlich-type polaronic system, based on a canonical transformation and a standard Landau-Pekar type variational wave function, is applied to the polaronic syst...
cEvidence is presented for the nite wave vector crossing of the two lowest one-dimensional spin-split subbands in quantum point contacts fabricated from two-dimensional hole gases with strong spin-or...
Magnetoelectric coupling terms are derived in piezoelectric/magnetostrictive (multiferroic) thin film heterostructures using Landau-Ginzburg free energy expansions in terms of strain and by con-sideri...
We present transport measurements of a tunable silicon metal-oxide-semiconductor double quantum dot device with lateral geometry. Experimentally extracted gate-to-dot capacitances show that the device...
We discuss the possibility of extending the RG flows to complex coupling spaces. We argue that the Fisher’s zeros are located at the boundary of the complex basin of attraction of IR fixed points.
We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong coupling with many flavours Nf of Wilson fermions in the fundamental representation, including the relev...
We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work, we introduce equ...
We investigate, via numerical simulations, the phase ordering kinetics of a two-dimensional soft-spin O(2) Ginzburg-Landau model when a reversible mode coupling is included via the conserved conjuga...
We present a superconducting qubit for the circuit quantum electrodynamics architecture that has a tunable coupling strength g. We show that this coupling strength can be tuned from zero to values tha...
