“…How would the introduction of the gain and loss channel affect the fluctuation properties of the pumped heat? Another question to be answered regards the influence of interaction between multiple degrees of freedom, like in the hybridized systems [75], thermal radiation systems [63], and multi-component systems [50]. Also, the geometric heat pump effect in the strong system-bath coupling regime [43] is an interesting topic.…”

“…As we concentrate on the geometric heat pump, we merely mention some of them, with no attempt at a thorough covering. The stochastic-resonance-like heat pump [20], the passive phonon pump [17], the heat pump approaching Carnot efficiency [19], and radiative heat pump effect [63], as prominent examples, have been proposed and analyzed. It is foreseeable that the geometric concepts would instill further insights into these theoretical modeling [64] and the future experimental design of heat engines.…”

The second law of thermodynamics dictates that heat simultaneously flows from the hot to cold bath on average. To go beyond this picture, a range of works in the past decade show that, other than the average dynamical heat flux determined by instantaneous thermal bias, a non-trivial flux contribution of intrinsic geometric origin is generally present in temporally driven systems. This additional heat flux provides a free lunch for the pumped heat and could even drive heat against the bias. We review here the emergence and development of this so called "geometric heat pump", originating from the topological geometric phase effect, and cover various quantum and classical transport systems with different internal dynamics. The generalization from the adiabatic to the non-adiabatic regime and the application of control theory are also discussed. Then, we briefly discuss the symmetry restriction on the heat pump effect, such as duality, supersymmetry and timereversal symmetry. Finally, we examine open problems concerning the geometric heat pump process and elucidate their prospective significance in devising thermal machines with high performance.

“…It also shares some common features with the super-radiance and superconducting transitions [Cho et al, 2005], the synchronization of clocks described by C. Huygens, the tuning of piano strings [Weinreich, 1977] and the collective phase transitions described for non-linear systems [Strogatz, 2012]. Indeed, a number of classical oscillatory systems have also shown exceptional points in the spectrum and their associated dynamical phase transition [Anderson, 1954, Celardo and Kaplan, 2009, Rotter and Bird, 2015, Domínguez-Rocha et al, 2020 and they have been exploited in a wide range of innovative applications that include, the sub-wave length field control [Bustos-Marún et al, 2014], energy harvesting and energy management [Li et al, 2019, Fernández-Alcázar et al, 2020, Fernández-Alcázar et al, 2021, among many others. All those cases contain, often hidden behind FGR-like approximations, the thermodynamic limit required by Anderson.…”

Through an appropriate election of the molecular orbital basis, we show analytically that the molecular dissociation occurring in a Heyrovsky reaction can be interpreted as a Quantum Dynamical Phase Transition, i.e., an analytical discontinuity in the molecular energy spectrum induced by the catalyst. The metallic substrate plays the role of an environment that produces an energy uncertainty on the adatom. This broadening induces a critical behavior not possible in a quantum closed system. We use suitable approximations on symmetry, together with both Lanczos and canonical transformations, to give analytical estimates for the critical parameters of molecular dissociation. This occurs when the bonding to the surface is √ 2 times the molecular bonding. This value is slightly weakened for less symmetric situations. However simple, this conclusion involves a high order perturbative solution of the molecule-catalyst system. This model is further simplified to discuss how an environment-induced critical phenomenon can be evaluated through an idealized perturbative tunneling microscopy set-up. In this case, the energy uncertainties in one or both atoms are either Lorentzian or Gaussian. The former results from the Fermi Golden Rule, i.e., a Markovian approximation. The Gaussian uncertainty, associated with non-Markovian decoherent processes, requires the introduction of a particular model of a spin bath.

“…[30][31][32][33] Only recently, photonic designs that enforce directional radiation transfer via temporal modulations are being explored. [34][35][36][37] In this paper we consider an adiabatic thermal radiation pump which consists of a siliconbased square resonator exchanging, in the near-field, radiation with two thermal reservoirs which are at the same temperature. Two circular domains of the resonator are adiabatically driven by an out-of-phase periodic modulation.…”

We numerically implement the concept of thermal radiation pumps in realistic photonic circuits and demonstrate their efficiency to control the radiation current, emitted between two reservoirs with equal temperature. The proposed pumping scheme involves a cyclic adiabatic modulation of two parameters that control the spectral characteristics of the photonic circuit. We show that the resulting pumping cycle exhibits maximum radiation current when a cyclic modulation of the system is properly engineered to be in the proximity of a resonance degeneracy in the parameter space of the photonic circuit. A developed Floquet scattering framework, which in the adiabatic 1
