2021-11-08 | Faking Gauge Coupling Unification in String Theory | Gauge coupling unification misleads infrared observers if new gauge bosons do
not simultaneously come into the spectrum. Though easy to engineer in gauge
theory, the situation in string theory is nuanced, due to moduli dependence. We
study the possibility of faking gauge coupling unification in the context of

2021-11-12 | Excite atom-photon bound state inside the coupled-resonator waveguide coupled with a giant atom | It is of fundamental interest in controlling the light-matter interaction for
a long time in the field of quantum information processing. However, usual
excitation with the propagating photon can hardly excite a localized state of

interaction (DMI) between an in-plane magnetized Co layer and a perpendicularly

modeled through the coupled mode theory to determine the behaviour of
eigenstates and eigenvalu... | 2112.03681v1 |
2021-12-07 | Coupling function from bath density of states | Modelling of an open quantum system requires knowledge of parameters that

2021-12-13 | Quantum indirect synchronization | It is well known that a system with two or more levels exists a limit cycle
and can be synchronized with an external drive when the system and the drive
are directly coupled. One might wonder if a system can synchronize with the
external drive when they are not coupled directly. In this paper, we examine
this case by c... | 2112.06722v1 |

study the coupled m... | 2112.12832v1 |
2021-12-25 | A description of interpolation spaces for quasi-Banach couples by real $K$-method | The main aim of this paper is to develop a general approach, which allows to
extend the basics of Brudnyi-Kruglyak interpolation theory to the realm of
quasi-Banach lattices. We prove that all $K$-monotone quasi-Banach lattices
with respect to a $L$-convex quasi-Banach lattice couple have in fact a
stronger property of... | 2112.13248v1 |

2021-12-31 | Non-local triple quantum dot thermometer based on Coulomb-coupled systems | Recent proposals towards non-local thermoelectric voltage-based thermometry,
in the conventional dual quantum dot set-up, demand an asymmetric step-like
system-to-reservoir coupling around the ground states for optimal operation
(Physica E, 114, 113635, 2019). In addition to such demand for unrealistic
