Molecular nanomagnets (MNMs), molecules containing interacting spins, have been a
playground for quantum mechanics. They are characterized by many accessible low-energy …

Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

Magnetism is one of the largest, most fundamental, and technologically most relevant fields
of condensed-matter physics. Traditionally, two basic magnetic phases have been …

The Landauer principle states that at least k BT ln 2 of energy is required to erase a 1-bit
memory, with k BT the thermal energy of the system. We study the effects of inertia on this …

We consider how the energy cost of bit reset scales with the time duration of the protocol. Bit
reset necessarily takes place in finite time, where there is an extra penalty on top of the …

Magnetic molecules, modelled as finite-size spin systems, are test-beds for quantum
phenomena and could constitute key elements in future spintronics devices,,–, long-lasting …

The dissipation generated during a quasistatic thermodynamic process can be
characterised by introducing a metric on the space of Gibbs states, in such a way that …

We present an overview of recent advances in the study of energy dynamics and
mechanisms for energy conversion in qubit systems with special focus on realizations in …

Landauer's principle formulated in 1961 states that logical irreversibility implies physical
irreversibility and demonstrated that information is physical. Here we formulate a new …

Information is physical but information is also processed in finite time. Where computing
protocols are concerned, finite-time processing in the quantum regime can dynamically …
