Wess-Zumino terms in 0+1 SU(N) superspin systems
J. S. Morales, M. N. Kiselev
These notes present a self-contained introduction to Wess-Zumino (WZ) terms in quantum systems with symmetry, emphasizing the interplay between geometry, topology, and cond…
Noise signatures of a charged Sachdev-Ye-Kitaev dot in mesoscopic transport
Andrei I. Pavlov, Mikhail N. Kiselev
We investigate quantum noise in a mesoscopic quantum dot serving as a realization of the charged Sachdev-Ye-Kitaev (SYK) model weakly coupled to a fermionic lead via a tunnel conta…
Seven Etudes on dynamical Keldysh Model
D. V. Efremov, M. N. Kiselev
We present a comprehensive pedagogical discussion of a family of models describing the propagation of a single particle in a multicomponent non-Markovian Gaussian random field. We…
Universal relations between thermoelectrics and noise in mesoscopic transport across a tunnel junction
Andrei I. Pavlov, Mikhail N. Kiselev
We develop a unified theory of weakly probed differential observables for currents and noise in transport experiments. Our findings uncover a set of universal transport relations b…
